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
- by defaut using FrSky Hub protocol (for example er9x): A1=RX voltage (set the ratio to 12.7 and adjust with offset), A2=battery voltage FS-CVT01 (set the ratio to 12.7 and adjust with offset) 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).

Telemetry supported:
- A1 = battery voltage including "recovered" battery voltage from corrupted telemetry packets
- A2 = battery voltage from only good packets
- You must adjust the battery voltage offset with a voltmeter since there are some large differences between the models
- A2 = battery voltage from only good telemetry packets
- For both A1 and A2, you must set the ratio to 12.7 and then adjust the offset to match the battery voltage using a voltmeter since there are some large differences between the models
- RX_RSSI = TQly = percentage of received telemetry packets (good and corrupted) received from the model which has nothing to do with how well the RX is receiving the TX
Option for this protocol corresponds to the CC2500 fine frequency tuning. This value is different for each Module and **must** be accurate otherwise the link will not be stable.

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
Basic telemetry is available if RX supports it: TX_RSSI, A1 (set the ratio to 12.7) and A2 (set the ratio to 12.7)
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.

Option=0 -> normal Bayang protocol
Option=1 -> enable telemetry with [Silverxxx firmware](https://github.com/silver13/H101-acro/tree/master). Value returned to the TX using FrSkyD Hub are RX RSSI, TX RSSI, A1=uncompensated battery voltage, A2=compensated battery voltage

Option=2 -> enable analog aux channels with [NFE Silverware firmware](https://github.com/NotFastEnuf/NFE_Silverware). Two otherwise static bytes in the protocol overridden to add two 'analog' (non-binary) auxiliary channels.
