# Protocols details
Here are detailed descriptions of every supported protocols (sorted by RF modules) as well as the available options for each protocol.
If you want to see examples of model configurations see the [Models](docs/Models.md) page.
The Deviation project (on which this project was based) have a useful list of models and protocols [here](http://www.deviationtx.com/wiki/supported_models).
## Useful notes and definitions
- **Channel Order** - The channel order assumed in all the documentation is AETR. You can change this in the compilation settings or by using a precompiled firmware. The module will take whatever input channel order you have choosen and will rearrange them to match the output channel order required by the selected protocol.
- **Channel ranges** - A radio output of -100%..0%..+100% will match on the selected protocol -100%,0%,+100%. No convertion needs to be done.
- **Extended limits supported** - A channel range of -125%..+125% will be transmitted. Otherwise it will be truncated to -100%..+100%.
- **Italic numbers** are referring to protocol/sub_protocol numbers that you should use if the radio (serial mode only) is not displaying (yet) the protocol you want to access.
- **Autobind protocol** - The transmitter will automatically initiate a bind sequence on power up or model/protocol selection. This is for models where the receiver expects to rebind every time it is powered up. In these protocols you do not need to press the bind button at power up to bind, it will be done automatically. In case a protocol is not autobind but you want to enable it, change the "Autobind" or "Bind on channel" on OpenTX setting to Y for the specific model/entry.
## Bind on channel feature
* Bind on channel can be globally enabled/disabled in _config.h using ENABLE_BIND_CH. Any channel between 5 and 16 can be used by configuring BIND_CH in _config.h. Default is 16.
* Bind on channel can be locally enabled/disabled by setting "Bind on channel" or "Autobind" per model for serial or per dial switch number for ppm.
* Once activated, any bind will only happen if all these elements are happening at the same time:
- Bind on channel = Y
- Throttle = LOW (<-95%)
- Bind channel (16 by default) is going from -100% to +100%
- **It's recommended to combine the bind switch with Throttle cut or throttle at -100% to drive the bind channel. This will prevent to launch a bind while flying** and enable you to use the bind switch for something else.
## Protocol selection in PPM mode
The protocol selection is based on 2 parameters:
* selection switch: this is the rotary switch on the module numbered from 0 to 15
- switch position 0 is to select the Serial mode for er9x/erskyTX/OpenTX radio
- switch position 15 is to select the bank
- switch position 1..14 will select the protocol 1..14 in the bank *X*
* banks are used to increase the amount of accessible protocols by the switch. There are up to 5 banks giving acces to up to 70 protocol entries (5 * 14). To modify or verify which bank is currenlty active do the following:
- turn on the module with the switch on position 15
- the number of LED flash indicates the bank number (1 to 5 flash)
- to go to the next bank, short press the bind button, this action is confirmed by the LED staying on for 1.5 sec
Here is the full protocol selection procedure:
1. turn the selection switch to 15
2. power up the module
3. the module displays the current bank by flashing the LED x number of times, x being between 1 and up to 5
4. a short press on the bind button turns the LED on for 1 sec indicating that the system has changed the bank
5. repeat operation 3 and 4 until you have reached the bank you want
6. power off
7. change the rotary switch to the desired position (1..14)
8. power on
9. enjoy
Notes:
* **The protocol selection must be done before the module is turned on**
* The protocol mapping based on bank + rotary switch position can be seen/modified at the end of the file [_Config.h](/Multiprotocol/_Config.h)**
## Serial mode
Serial mode is selected by placing the rotary switch to position 0 before power on of the radio.
You've upgraded the module but the radio does not display the name of the protocol you are loking for:
* erskyTX:
- Place the file [Multi.txt](https://raw.githubusercontent.com/pascallanger/DIY-Multiprotocol-TX-Module/master/Multiprotocol/Multi.txt) (which is part of the MPM source files) on the root of your SD card.
- If the entry still does not appear or is broken, [upgrade](https://openrcforums.com/forum/viewtopic.php?f=7&t=4676) to version R222d2 or newer.
* OpenTX:
- Upgrade to the latest version of OpenTX.
- If still not listed, use the Custom entry along with the protocol and sub_protocol values indicated by the italic numbers under each protocol. You'll find a summary of the protocols and numbers to use in table below.

Extended limits and failsafe supported
Telemetry enabled protocol:
- by defaut using FrSky Hub protocol (for example er9x): RX(A1), battery voltage FS-CVT01(A2) and RX&TX RSSI
- 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.
**RX_Num is used to give a number a given RX. You must use a different RX_Num per RX. A maximum of 64 AFHDS2A RXs are supported.**
AFHDS2A_LQI_CH is a feature which is disabled by defaut in the _config.h file. When enabled, it makes LQI (Link Quality Indicator) available on one of the RX ouput channel (5-14).

Models: FrSky v1.xxx receivers X4R, X6R and X8R. Protocol also known as D16 v1 FCC/LBT.
Extended limits and failsafe supported
Telemetry enabled for A1 (RxBatt), A2, RSSI, TX_RSSI, TX_LQI and Hub. Lowest the TX_LQI value is best the quality link is, it's a good indicator of how well the module is tuned.
Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.
Check the [Frequency Tuning page](/docs/Frequency_Tuning.md) to determine it.

### Sub_protocol Cloned_8 - *5*
Use the identifier learnt from another FrSky radio when binding with the FrSkyRX/CloneTX mode.
8 channels.
## FRSKYX2 - *64*
Same as [FrskyX](Protocols_Details.md#FRSKYX---15) but for D16 v2.1.0 FCC/LBT.
## FRSKY_RX - *55*
### Sub_protocol RX - *0*
The FrSky receiver protocol enables master/slave trainning, separate access from 2 different radios to the same model,...
Auto detection of the protocol used by a TX transmitting FrSkyD/D8, FrSkyX/D16 v1.xxx FCC/LBT or FrSkyX/D16 v2.1.0 FCC/LBT at bind time.
Available in OpenTX 2.3.3, Trainer Mode Master/Multi
Extended limits supported
For **FrSkyX, RX num must match on the master and slave**. This enables a multi student configuration for example.
Option for this protocol corresponds to fine frequency tuning.
If the value is equal to 0, the RX will auto tune otherwise it will use the indicated value.
This value is different for each Module and **must** be accurate otherwise the link will not be stable.
Check the [Frequency Tuning page](/docs/Frequency_Tuning.md) to determine it.
Low power: enable/disable the LNA stage on the RF component to use depending on the distance with the TX.
### Sub_protocol CloneTX - *1*
This subprotocol makes a clone of a TX identifier transmitting FrSkyD/D8, FrSkyX/D16 v1.xxx FCC/LBT and FrSkyX/D16 v2.1.0 FCC/LBT.
There are 3 slots available, 1 slot for D8 cloning, 1 slot for FrSkyX (D16v1) cloning and 1 slot for FrSkyX2 (D16v2.1.0) cloning.
The same TX or different TXs can be used for each slot but a maximum of 1 per slot.
If you launch the FrSky_RX/CloneTX protocol and do a bind with a TX transmitting with the D8 protocol, it will be saved in the slot D8. Same for D16v1 and D16v2.1 .
Then the system will alow you to enable cloning as you wish for each model using the FrSkyD/X/X2 "Cloned" subprotocol. This way you can have models working with the original MPM indentifier and models which are shared by both the cloned TX and MPM.
Clone mode operation:
- Select the FrSky_RX protocol, subprotocol CloneTX
- Select on the TX to be cloned the protocol you want to clone the identifier from: FrSkyD/D8 or FrSkyX/D16 v1.xxx FCC/LBT or FrSkyX/D16 v2.1.0 FCC/LBT
- Place both the TX and MPM in bind mode
- Wait for the bind to complete
- To use the cloned TX identifier, open a new model select the protocol you just cloned/binded and select the subprotocol "Cloned"
Notes:
- OpenTX 2.3.8 N184 (nightly) or later is needed to have access to the "D8Cloned" and "D16Cloned" subprotocols, D16v2.1 "Cloned" is available under FrSkyX2/Cloned.
- For FrSkyD, only the RX number used during bind is cloned -> you can't use RX num anymore
- For FrSkyX and FrSkyX2, RX number has to be adjusted on each model to match the original TX model
## HITEC - *39*

### Sub_protocol MINIMA - *2*
MINIMA, MICRO and RED receivers. Also used by ARES planes.
## HoTT - *57*
Models: Graupner HoTT receivers (tested on GR-12, GR-12L, GR-16 and Vector).
Extended limits, failsafe and LBT supported.
Full telemetry and full text config mode are available starting from OpenTX 2.3.8N226.
**RX_Num is used to give a number to a given RX. You must use a different RX_Num per RX. A maximum of 64 HoTT RXs are supported.**
**Failsafe MUST be configured once with the desired channel values (hold or position) while the RX is up (wait 10+sec for the RX to learn the config) and then failsafe MUST be set to RX/Receiver otherwise the servos will jitter!!!**
The RX and sensors/FC features configuration are done through the OpenTX script "Graupner HoTT.lua".
Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.

## OMP - *77*
Model: OMPHOBBY M2 Heli, T720 RC Glider
Telemetry supported with A1=battery voltage (you need to adjust the offset with a voltmeter since there are some large differences between the models), RX_RSSI = TQly = percentage of received telemetry packets which has nothing to do with well the RX is receiving the TX but instead how well the TX=multi module is receiving the RX.
Option for this protocol corresponds to fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.
Check the [Frequency Tuning page](/docs/Frequency_Tuning.md) to determine it.
This protocol is using both the CC2500 and NRF24L01 to control the model and read the telemetry.

RX output will match the Devo standard EATR independently of the input configuration AETR, RETA... unless on OpenTX 2.3.3+ you use the "Disable channel mapping" feature on the GUI.
Basic telemetry is available if RX supports it: TX_RSSI, A1 and A2
Bind procedure using serial:
- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
- Turn on the TX, set protocol = Devo with option=0, turn off the TX (TX is now in autobind mode).
- Turn on RX (RX LED fast blink).
- Turn on TX (RX LED solid, TX LED fast blink).
- Wait for bind on the TX to complete (TX LED solid).
- Make sure to set a uniq RX_Num value for model match.
- Change option to 1 to use the global ID.
- Do not touch option/RX_Num anymore.
Bind procedure using PPM:
- With the TX off, put the binding plug in and power on the RX (RX LED slow blink), then power it down and remove the binding plug. Receiver should now be in autobind mode.
- Turn on RX (RX LED fast blink).
- Turn the dial to the model number running protocol DEVO on the module.
- Press the bind button and turn on the TX. TX is now in autobind mode.
- Release bind button after 1 second: RX LED solid, TX LED fast blink.
- Wait for bind on the TX to complete (TX LED solid).
- Press the bind button for 1 second. TX/RX is now in fixed ID mode.
- To verify that the TX is in fixed mode: power cycle the TX, the module LED should be solid ON (no blink).
- Note: Autobind/fixed ID mode is linked to the RX_Num number. Which means that you can have multiple dial numbers set to the same protocol DEVO with different RX_Num and have different bind modes at the same time. It enables PPM users to get model match under DEVO.

This roughly corresponds to the number of channels supported, but many of the newer 6-channel receivers actually support the WK2801 protocol. It is recommended to try the WK2801 protocol 1st when working with older Walkera models before attempting the WK2601 or WK2401 mode, as the WK2801 is a superior protocol. The WK2801 protocol supports up to 8 channels.

Notes:
- The "AUTO" sub protocol is recommended to automatically select the best settings for your DSM RX. If the RX doesn't bind or work properly after bind, don't hesitate to test different combinations of sub protocol and number of channels until you have something working.
- Servo refresh rate is 22ms unless you select 11ms available in OpenTX 2.3.10+
- RX output will match the Spektrum standard TAER independently of the input configuration AETR, RETA... unless on OpenTX 2.3.3+ you use the "Disable channel mapping" feature on the GUI.
- RX output will match the Spektrum standard throw (1500µs +/- 400µs -> 1100..1900µs) for a 100% input. This is true for both Serial and PPM input. For PPM, make sure the end points PPM_MIN_100 and PPM_MAX_100 in _config.h are matching your TX ouput. The maximum ouput is 1000..2000µs based on an input of 125%.
- If you want to override the above and get maximum throw either uncomment in _config.h the line #define DSM_MAX_THROW or on OpenTX 2.3.3+ use the "Enable max throw" feature on the GUI (0=No,1=Yes). In this mode to achieve standard throw use a channel weight of 84%.
- TH_KILL is a feature which is enabled on channel 14 by default (can be disabled/changed) in the _config.h file. Some models (X-Vert, Blade 230S...) require a special position to instant stop the motor(s). If the channel 14 is above -50% the throttle is untouched but if it is between -50% and -100%, the throttle output will be forced between -100% and -150%. For example, a value of -80% applied on channel 14 will instantly kill the motors on the X-Vert.
- To allow SAFE to be ON with a switch assignment you must remove the bind plug after powering up the RX but before turning on the TX to bind. If you select Autodetect to bind, The MPM will choose DSMX 11ms and Channels 1-7 ( Change to 1-9 if you wish to assign switch above channel 7 ). Then in order to use the manuals diagram of both sticks "Down-Inside" to set a SAFE Select Switch Designation, you must have Throttle and Elevator channels set to Normal direction but the Aileron and Rudder set to Reverse direction. If setting up a new model with all channels set to Normal you can hold both sticks "Down- OUTSIDE" to assign the switch with 5x flips. Tested on a Mode2 radio.
Option=number of channels from 3 to 12. Option|0x80 enables Max Throw. Option|0x40 enables a servo refresh rate of 11ms.

## Cabell - *34*
Homegrown protocol with variable number of channels (4-16) and telemetry (RSSI, V1, V2).
It is a FHSS protocol developed by Dennis Cabell (KE8FZX) using the NRF24L01+ 2.4 GHz transceiver. 45 channels are used frequency hop from 2.403 through 2.447 GHz. The reason for using 45 channels is to keep operation within the overlap area between the 2.4 GHz ISM band (governed in the USA by FCC part 15) and the HAM portion of the band (governed in the USA by FCC part 97). This allows part 15 compliant use of the protocol, while allowing licensed amateur radio operators to operate under the less restrictive part 97 rules if desired.
Additional details about configuring and using the protocol are available at the RX project at: https://github.com/soligen2010/RC_RX_CABELL_V3_FHSS

- To run this protocol you need both CC2500 and NRF24L01 to be enabled for code reasons, only the CC2500 is really used.

If the model does not respond well to inputs or hard to bind, you can try to switch the emulation from the default NRF24L01 RF component to the CC2500 by using an option value (freq tuning) different from 0. Option in this case is used for fine frequency tuning like any CC2500 protocols so check the [Frequency Tuning page](/docs/Frequency_Tuning.md).

## V911S - *46*
This protocol is known to be problematic because it's using the xn297L emulation with a transmission speed of 250kbps therefore it doesn't work very well with every modules, this is an hardware issue with the accuracy of the components.
If the model does not respond well to inputs or hard to bind, you can try to switch the emulation from the default NRF24L01 RF component to the CC2500 by using an option value (freq tuning) different from 0. Option in this case is used for fine frequency tuning like any CC2500 protocols so check the [Frequency Tuning page](/docs/Frequency_Tuning.md).

# OpenLRS module
## OpenLRS - *27*
This is a reservation for OpenLRSng which is using Multi's serial protocol for their modules: https://openlrsng.org/. On the Multi side there is no protocol affected on 27 so it's just ignored.
