 - if using erskyTX and OpenTX: full telemetry information available
 - if telemetry is incomplete (missing RX RSSI for example), it means that you have to upgrade your RX firmware to version 1.6 or later. You can do it from an original Flysky TX or using a STLink like explained in [this tutorial](https://www.rcgroups.com/forums/showthread.php?2677694-How-to-upgrade-Flysky-Turnigy-iA6B-RX-to-firmware-1-6-with-a-ST-Link).

 Option is used to change the servo refresh rate. A value of 0 gives 50Hz (min), 70 gives 400Hz (max). Specific refresh rate value can be calculated like this option=(refresh_rate-50)/5.

-### Notes
- The "b" SPI files each contain one SPI byte per row. Multiple rows sharing the same `Packet ID` belong to one CSN-low SPI transaction.
- Files 03b–24b were all captured in **normal (post-bind) flight mode**. The TX had previously
-  completed a successful bind.
- File 01b and 02b are functionally **identical** captures (confirmed by direct payload comparison)
-  except for a tiny time offset (~7 µs between corresponding packets). This confirms the TX
-  transmits identically whether or not an RX is present; see Section 5.

-## 3. SPI Initialization Sequence
-
-The sequence below is from `02b` (PIDs 0–24), occurring over the first ~5 ms after the SPI
-bus becomes active (~150–335 ms after TX power-on due to startup delays).
-
-### 3.1 SV7241A Private Bank Registers
-
-The SV7241A (like BK2425) has bank-switched extended registers at addresses 0x18–0x1B.
-Register 0x1F selects the bank. These registers hold RF/analog calibration constants specific
-to the chip and **do not exist on nRF24L01+** — they are ignored when implementing with MPM.
-
-| PID | Register | Data Written | Purpose |
-|-----|----------|-------------|---------|
-| 0 | 0x1F | `00` | Select bank 0 |
-| 1 | 0x1B | `10 E1 D3 3D` | Bank 0 – RF calibration reg 1 |
-| 2 | 0x19 | `06 AA A2 DB` | Bank 0 – RF calibration reg 2 |
-| 3 | 0x1F | `01` | Select bank 1 |
-| 4 | 0x19 | `77 48 9A E8` | Bank 1 – internal reg |
-| 5 | 0x1B | `76 87 CA 01` | Bank 1 – internal reg |
-| 6 | 0x1F | `02` | Select bank 2 |
-| 7 | 0x1B | `A0 00 18 A0` | Bank 2 – internal reg |
-| 8 | 0x1F | `04` | Select bank 4 |
-| 9 | 0x18 | `01 00 F0 00` | Bank 4 – internal reg |
-| 10 | 0x1F | `05` | Select bank 5 |
-| 11 | 0x18 | `84 03 2A 03` | Bank 5 – internal reg |
-| 12 | 0x19 | `90 BF 00 00` | Bank 5 – internal reg |
-| 13 | 0x1A | `A0 0F 00 00` | Bank 5 – internal reg |

-| SV7241A | RF_DR (0=1Mbps, 1=2Mbps) | **2 Mbps**, max power |
-| nRF24L01+ | RF_DR_LOW (0=normal, 1=250kbps) | **250 kbps**, max power |
-
-→ On nRF24L01+, writing 0x26 would set **250 kbps** (not 2 Mbps). For MPM emulation the
-correct approach (same as FQ777) is `NRF24L01_SetBitrate(NRF24L01_BR_250K)` combined with
-`ssv_pack_dpl()` to produce a compatible air packet.
-
-**Startup timing:**
-
-The TX power-on to first SPI transaction takes ~150 ms (CE is held high from
-t = –72 ms until t = 0, then the ~150 ms wait elapses before SPI activity at t ≈ +181 ms in the
-02b file). The entire init register sequence completes in ~6 ms.
-
---
-
-## 4. Bind Sequence – Deep Analysis (02a + 02b)
-
-### 4.1 Overview
-
-After the ~150 ms startup wait, the TX sends exactly **400 bind packets** before switching to
-normal data mode.
-
-| Property | Value |
-|----------|-------|
-| Total bind packets | **400** |
-| Bind address | `E7 E7 E7 E7 67` (fixed broadcast) |
-| First bind packet channel | `0x00` (universal channel) |
-| Remaining 399 bind packet channels | Cycling: `0x49 → 0x34 → 0x26 → 0x07 → 0x49 → …` |
-| Bind packet payload | `20 14 07 03 TX_ID₀ TX_ID₁ TX_ID₂ CKSUM` |
-| Bind packet content | Identical across all 400 transmissions |
-
-The first bind packet is sent on RF channel **0x00**, ensuring a newly powered-on RX (sitting
-on its default channel) can hear the bind announcement regardless of any prior state. Subsequent
-bind packets cycle through the four data-hopping channels.
-
-### 4.2 Bind Packet Structure
-
-```
-Byte  0  1    2    3    4        5        6        7
-     [20 14   07   03   TX_ID₀  TX_ID₁  TX_ID₂  CKSUM]
-```
-
-| Byte | Value (this TX) | Description |
-|------|----------------|-------------|
-| B0 | `0x20` | Bind identifier byte (constant — marks this as a bind packet) |
-| B1 | `0x14` | Protocol variant constant (XBM-37 specific; FQ777 uses `0x15`) |
-| B2 | `0x07` | Protocol variant constant (XBM-37 specific; FQ777 uses `0x05`) |
-| B3 | `0x03` | Protocol variant constant (XBM-37 specific; FQ777 uses `0x06`) |
-| B4 | `0x91` | TX_ID byte 0 — unique per TX unit |
-| B5 | `0x05` | TX_ID byte 1 — unique per TX unit |
-| B6 | `0x05` | TX_ID byte 2 — unique per TX unit |
-| B7 | `0x9B` | Checksum = (TX_ID₀ + TX_ID₁ + TX_ID₂) & 0xFF = (0x91+0x05+0x05) & 0xFF |
-
-**Checksum formula for bind packet:** `B7 = (B4 + B5 + B6) & 0xFF`
-(This differs from the data packet checksum which sums B0–B6.)
-
-### 4.3 TX ID
-
-TX ID is **3 bytes** embedded in B4–B6 of the bind packet. This TX unit has:
-
-```
-TX_ID = [0x91, 0x05, 0x05]
-```
-
-After bind, the TX_ADDR is set to: `[TX_ID₀  TX_ID₁  TX_ID₂  0xE7  0x67]`
-= `[91  05  05  E7  67]`
-
-The RX extracts TX_ID from the bind packet and uses it to construct the matching address for
-normal data reception.
-
-### 4.4 Bind Channel Sequence (from 02b SPI decoded)
-
-```
-Packet #1:   ch=0x00  [20 14 07 03 91 05 05 9B]  ← universal announce
-Packet #2:   ch=0x49  [20 14 07 03 91 05 05 9B]
-Packet #3:   ch=0x34  [20 14 07 03 91 05 05 9B]
-Packet #4:   ch=0x26  [20 14 07 03 91 05 05 9B]
-Packet #5:   ch=0x07  [20 14 07 03 91 05 05 9B]
-Packet #6:   ch=0x49  [20 14 07 03 91 05 05 9B]
-...continues cycling 0x49→0x34→0x26→0x07...
-Packet #400: ch=0x26  [20 14 07 03 91 05 05 9B]  ← last bind
-```
-
-Channel usage across all 400 bind packets:
-
-| Channel | Count | Notes |
-|---------|-------|-------|
-| 0x00 | 1 | First packet only |
-| 0x49 (73 MHz) | 100 | Regular cycle |
-| 0x34 (52 MHz) | 100 | Regular cycle |
-| 0x26 (38 MHz) | 100 | Regular cycle (includes last bind packet) |
-| 0x07 (7 MHz) | 99 | Regular cycle |
-
-### 4.5 Bind-to-Normal Transition
-
-After the 400th bind packet the TX:
-
-1. Completes the 400th transmission (CE pulse ~1,172 µs, then CE low).
-2. Waits **~16.6 ms** (no SPI activity; firmware processing time).
-3. Writes the new TX_ADDR: `W_TX_ADDR [91 05 05 E7 67]` (SPI pid=1625 at t=1.175882 s).
-4. Immediately clears STATUS and starts normal data mode.
-5. First normal packet: ch=**0x07** (continuation of the hop sequence from where bind ended).
-
-```
-Last bind (400th):  t=1.159258 s, ch=0x26
-TX_ADDR change:     t=1.175882 s  (+16.6 ms gap)
-First data packet:  t=1.176619 s, ch=0x07  [E1 70 70 70 20 20 00 71]
-```
-
-### 4.6 IRQ / STATUS Analysis (from 02a Digital Capture)
-
-The IRQ line (active-low) is asserted by the SV7241A for every successfully transmitted packet
-(TX_DS interrupt):
-
-| Observation | Value |
-|-------------|-------|
-| Total IRQ assertions | 1,340 (matching 1,340 normal CE pulses) |
-| IRQ pulse duration (typical) | ~600 µs |
-| IRQ source | TX_DS only (TX complete) |
-| RX_DR interrupts | **Zero** — no data ever received |
-
-The SPI confirms there are **no `R_RX_PAYLOAD` (0x61) commands** in either 01b or 02b.
-Combined with `EN_RXADDR = 0x00` (all RX pipes disabled), it is impossible for the TX to
-receive data from the RX. This is confirmed by the STATUS register never showing bit6
-(RX_DR) = 1.
-
-One extended IRQ assertion of **15.9 ms** occurs at t=1.160476 s (immediately after the 400th
-bind packet). This is not an RX event — it is simply the TX_DS interrupt remaining uncleared
-while the firmware processes the bind-completion event and updates TX_ADDR. The IRQ is
-cleared when `W_STATUS [70]` is written at t=1.176254 s (pid=1626).
-
-### 4.7 CE Pulse Timing (from 02a)
-
-| Measurement | Value |
-|-------------|-------|
-| Normal CE pulse duration | min 1,165 µs, max 1,178 µs, **avg 1,172 µs** |
-| CE inter-pulse gap (end to start) | **~896 µs** |
-| Total cycle (CE high + gap) | **~2,068 µs** |
-| Pulse-to-pulse interval (high to high) | min 2.063 ms, max 20.686 ms, **avg 2.084 ms** |
-
-The 20.686 ms outlier corresponds to the bind-to-normal transition pause (~16.6 ms).
-
---
-
-## 5. Bind vs No-RX Comparison (01b vs 02b)
-
-**Finding: The TX transmits identically whether or not an RX is present.**
-
-| Metric | 01b (No RX) | 02b (With RX) |
-|--------|------------|----------------|
-| Total TX payloads | 1,352 | 1,345 |
-| Bind packets | 400 | 400 |
-| Bind packet content | `20 14 07 03 91 05 05 9B` | `20 14 07 03 91 05 05 9B` (identical) |
-| TX_ADDR change time | t=1.175899 s | t=1.175882 s |
-| TX_ADDR after bind | `[91 05 05 E7 67]` | `[91 05 05 E7 67]` (identical) |
-| Normal data payload (idle) | `E1 70 70 70 20 20 00 71` | `E1 70 70 70 20 20 00 71` (identical) |
-| Time offset between captures | — | ~7 µs per packet |
-
-The TX performs an automatic timed bind sequence (400 packets) and then switches to data mode
-unconditionally, regardless of RX acknowledgment. The TX **never knows** whether the RX
-accepted the bind. Bind is one-sided: the RX passively listens for the bind packet on ch=0x00
-(or the cycling channels), extracts the TX_ID and hop channels, and then follows the TX's
-normal data transmissions.

-Byte  0        1      2       3        4       5       6       7
-     [Throttle Rudder Aileron Elevator Flags1  Flags2  Flags3  CKSUM]
-```
-
-**Checksum (B7):** `B7 = (B0 + B1 + B2 + B3 + B4 + B5 + B6) & 0xFF`
-
-All 8-byte checksum values have been verified against this formula across all capture files.
-
-### 6.2 Stick Channels (B0–B3)
-
-| Byte | Channel | Min | Center | Max | Notes |
-|------|---------|-----|--------|-----|-------|
-| B0 | Throttle | `0xE1` | `0x70` | `0x00` | Non-return throttle |
-| B1 | Rudder (Yaw) | `0x00` | `0x70` | `0xE1` | |
-| B2 | Aileron (Roll) | `0xE1` | `0x70` | `0x00` | |
-| B3 | Elevator (Pitch) | `0xE1` | `0x70` | `0x00` | |
-
-All analog channels use the same range: **0x00 – 0xE1** (0 – 225 decimal) with center at
-**0x70** (112 decimal).
- Throttle, Aileron, and Elevator use reversed state (0xE1...0x70...0x00).
-
-### 6.3 Flags Byte 1 (B4)
-
-| Value | Meaning | Description |
-|-------|---------|-------------|
-| `0x20` | **Trim Elevator Center** | Resets at TX start |
-| `0x21 up to 0x40` | Trim elevator **forward** | 32 Clicks to max |
-| `0x1F downto 0x01` | Trim elevator **back** | 31 Clicks to max |
-
-### 6.4 Flags Byte 2 (B5)
-
-| Value | Meaning | Description |
-|-----|------|-------------|
-| `0x20` | **Trim Aileron Center** | Resets at TX start |
-| `0x21 up to 0x40` | Trim aileron **left** | 32 Clicks to max |
-| `0x1F down to 0x01` | Trim aileron **right** | 31 Clicks to max |
-| `0x80` | OK button | OK pressed (`0x20` → `0xA0`) |
-
-`B5 bit7` is an OR mask on top of trim value (`B5_with_OK = B5_trim | 0x80`), e.g.
-center `0x20 -> 0xA0`, right-max `0x01 -> 0x81`.
-
-### 6.5 Flags Byte 3 (B6)
-
-| Bits | Mask | Name | Description |
-|------|------|------|-------------|
-| [1:0] | `0x03` | Rate mode | `0x00`=rate 1 (slow), `0x01`=rate 2, `0x02`=rate 3 (fast) |
-| 2 | `0x04` | LED off | `0`=LED lights ON, `1`=LED lights OFF |
-| 3 | `0x08` | RTH | `1`=return-to-home active |
-| 4 | `0x10` | Headless | `1`=headless mode active |
-| 5 | `0x20` | Video | `1`=video recording active |
-| 6 | `0x40` | Picture | `1`=photo capture triggered |
-| 7 | `0x80` | Flip | `1`=3D flip command |
-
-Normal state: `B6 = 0x00` (rate 1, LED on, no special modes)
-
-### 6.6 Return-to-Home (RTH)
-
-Updated analysis of **file 12b** (RTH OFF in first half, ON in second half):
-
- RTH-OFF payload is steady at `7E 70 70 70 20 20 00 0E`.
- After the OFF→ON transition, the payload changes to `7E 70 70 70 20 20 08 16`.
- The persistent functional change in this capture is `B6: 0x00 -> 0x08`
-  (bit3 asserted when RTH is ON).
-
-In this export, RTH is represented in the steady 8-byte payload by `B6 bit3`.
-
-### 6.7 Example Payloads

-| Payload | Meaning |
-|---------|---------|
-| `E1 70 70 70 20 20 00 71` | Throttle low `0xE1`, all sticks center `0x70`, LED on, no special modes `0x00` |

-## 7. Per-Channel Control Analysis (03b – 24b)
-
-All control captures were taken in post-bind normal mode. Hopping channels confirmed active:
-`0x07, 0x49, 0x34, 0x26` (cyclic). Average packet interval: **~2.07 ms** across all files.
-
-### 03b – Aileron (Roll)
-
- **Affected byte:** B2  
- Range observed: `0xE1` (full left) → `0x70` (center) → `0x00` (full right)  
-
-### 04b – Elevator (Pitch)
-
- **Affected byte:** B3  
- Range observed: `0x00` (full back) → `0x70` (center) → `0xE1` (full forward)
-
-### 05b – Throttle
-
- **Affected byte:** B0  
- Range observed: `0xE1` (low minimum) ↔ `0x70` (center) ↔ `0x00` (full maximum)  
- Non-return throttle (stick does not spring back to center)
-
-### 06b – Rudder (Yaw)
-
- **Affected byte:** B1  
- Range observed: `0x00` (full left) → `0x70` (center) → `0xE1` (full right)  
- Note: B0 (throttle) also varies in this capture because left stick controls both
-  throttle (up/down) and rudder (left/right) Mode 2 transmitter
-
-### 07b – Rate Mode Switch
-
- **Affected byte:** B6 bits[1:0]  
- `B6 = 0x00`: Rate 1 (slowest/beginner)  
- `B6 = 0x01`: Rate 2 (intermediate)  
- `B6 = 0x02`: Rate 3 (fastest/expert)
-
-### 08b – Flip Switch
-
- **Affected byte:** B6 bit7  
- `B6 = 0x00`: No flip; `B6 = 0x80`: 3D flip command active  
- While flip is held: throttle (B0) increments slightly (`0x82` → `0x83`)
-
-### 09b – Video Switch
-
- **Affected byte:** B6 bit5  
- `B6 = 0x00`: Video off; `B6 = 0x20`: Video recording active  
- Toggle on/off: transitions between these two states
-
-### 10b – Picture Switch (3×)
-
- **Affected byte:** B6 bit6  
- `B6 = 0x00`: Idle; `B6 = 0x40`: Photo capture triggered (momentary)
-
-### 11b – Headless Switch
-
- **Affected byte:** B6 bit4  
- `B6 = 0x00`: Headless off; `B6 = 0x10`: Headless mode active
-
-### 12b – Return to Home Switch
-
- **Capture split tested:** first half RTH OFF, second half RTH ON.
- **RTH OFF payload:** `7E 70 70 70 20 20 00 0E`
- **RTH ON payload:** `7E 70 70 70 20 20 08 16`
- **Primary byte change:** `B6: 0x00 -> 0x08`
-  - `B6 bit3` is asserted when RTH is active in this capture
- **Minor secondary variation while ON:** `B0` occasionally increments `0x7E -> 0x7F`,
-  producing checksum `0x16 -> 0x17`
- All other payload bytes remain unchanged across the OFF→ON transition in this file.
-
-### 13b – LED Lights Switch
-
- **Affected byte:** B6 bit2  
- `B6 = 0x00`: LED lights **ON** (default)

- Note: Inverted logic — bit2=1 means OFF
-
-### 14b – OK Switch
-
- **Affected byte:** B5 bit7  
- `B5 = 0x20`: OK button not pressed  
- `B5 = 0xA0`: OK button pressed (0x20 | 0x80)
-
-### 20b – Elevator Trim Center → Forward Max (32 clicks)
-
- **Affected byte:** B4 (elevator trim)
- Observed progression: `0x20 -> ... -> 0x40`
- Endpoint in this capture: `B4 = 0x40` (forward max)
- `B5` remains `0x20`; `B6` remains `0x00`
-
-### 21b – Elevator Trim Center → Back Max (31 clicks)
-
- **Affected byte:** B4 (elevator trim)
- Observed progression: `0x20 -> ... -> 0x01`

- `B4` remains `0x20`; `B6` remains `0x00`
-
-### 24b – Trim Endpoints + OK Button (2 presses)
-
- Fixed trim baseline in this capture:
-  - `B4 = 0x40` (elevator forward max)
-  - `B5 trim = 0x01` (aileron right max)
- **OK effect:** `B5 bit7` toggles over trim baseline:
-  - not pressed: `B5 = 0x01`
-  - pressed: `B5 = 0x81` (`0x01 | 0x80`)
- `B6` remains `0x00` throughout.

-## 8. RF Timing Summary
-
-### 8.1 Per-Packet SPI Cycle (02b decoded)
-
-Each packet transmission consists of 4 SPI transactions:
-
-```
-1. W_STATUS [27] = 0x70    → Clear TX_DS / MAX_RT / RX_DR interrupt flags
-2. FLUSH_TX [E1]           → Empty TX FIFO
-3. W_RF_CH  [25] = <ch>    → Set hop channel
-4. W_TX_PAYLOAD [A0] = 8B  → Write 8-byte payload to TX FIFO
-                             [CE pulse ~1,172 µs to transmit]
-                             [~896 µs gap before next cycle]
-```
-
-### 8.2 Bind Phase Timing
-
-| Event | Timestamp (02b) |
-|-------|----------------|
-| Init register writes complete | t = 0.186 s |
-| Startup wait completes | t = 0.335 s (~150 ms) |
-| First bind packet (ch=0x00) | t = 0.335838 s |
-| 400th (last) bind packet (ch=0x26) | t = 1.159258 s |
-| TX_ADDR change to data address | t = 1.175882 s (+16.6 ms) |
-| First normal data packet | t = 1.176619 s |
-
-Total bind phase duration: **~0.824 s** (150 ms wait + ~674 ms for 400 packets at 2.07 ms each)
-
-### 8.3 Normal Data Phase Timing
-
-| Event | Interval |
-|-------|---------|
-| Packet 1 → 2 (startup) | 0.918 ms |
-| Packet 2 → 3 (startup) | 0.916 ms |
-| Packet 3 → 4 (startup) | 1.491 ms |
-| Steady state (4+) | **~2.070 ms** per packet |
-
-The first 3 packets after bind-to-data transition have shorter intervals, then settle into the
-steady 2.07 ms period.
-
-### 8.4 STATUS Byte Values Observed
-
-| STATUS | Meaning | When seen |
-|--------|---------|-----------|
-| `0x0E` | TX FIFO not full, RX FIFO empty, all interrupts clear | Normal/idle |
-| `0x2E` | TX_DS = 1 (TX complete interrupt), TX FIFO not full | After each TX packet |
-
-RX_DR (bit6) is **never set** in any STATUS byte — confirming no data is ever received.

-### 9.5 Address Management

-```c
-// TX init:

-rx_tx_addr[3] = 0xE7;
-rx_tx_addr[4] = 0x67;
-// rx_tx_addr[0] and [1] are random/unique to the TX
-// rx_tx_addr[2] now varies by changing receiver number (0-63) for model match
-
-// Bind address (used during bind):
-NRF24L01_WriteRegisterMulti(NRF24L01_10_TX_ADDR, XBM37_bind_addr, 5);
-
-// After 400th bind packet, switch to data address:
-NRF24L01_WriteRegisterMulti(NRF24L01_10_TX_ADDR, rx_tx_addr, 5);
-```
-
-### 9.6 RF Init
-
-```c
-void XBM37_RF_init() {
-    NRF24L01_Initialize();
-    NRF24L01_WriteRegisterMulti(NRF24L01_10_TX_ADDR, XBM37_bind_addr, 5);
-    NRF24L01_WriteReg(NRF24L01_01_EN_AA, 0x00);      // no auto-ACK

-    NRF24L01_WriteReg(NRF24L01_1C_DYNPD, 0x01);      // DPL pipe 0

-### 9.7 Air Encoding
-
-Because both the XBM-37 TX and RX use SV7241A (a BK2425 derivative), the air packet format is
-the SV7241A Enhanced ShockBurst encoding. When implementing with nRF24L01+, the same
-`ssv_pack_dpl()` function used in the FQ777 protocol must be applied to convert the raw 8-byte
-payload into the 12-byte packed representation that nRF24L01+ transmits at 250 kbps to produce
-a compatible on-air signal.
