How to switch the protocol

Note: Switching internal protocol is only available for the Frsky version radio transmitter. ExpressLRS version can only switch to the external TX module.

To change protocols and TX module, here are the steps:

Power the radio transmitter off;
Press and hold the BIND button while powering the radio transmitter back on;
Then the flash color and times of the LED before buzzer alarms will change, according to the tables above.

The Frsky version could support 4 different internal protocols, including Frsky D16 FCC, Frsky D16 LBT, Frsky D8, and Futaba S-FHSS. The protocol is indicated by the flashing times of the LED when power on, before the buzzer alarms.

Frsky Version
LED Status	Protocol Version
Red Flash once	Internal Frsky D16 FCC (ACCST 1.X Version)
Red Flash twice	Internal Frsky D16 LBT (ACCST 1.X Version)
Red Flash Three Times	Internal Frsky D8
Red Flash Four Times	Internal Futaba S-FHSS
Purple Flash Three Times Quickly	Internal TX Module Off and Run External TX Module

ExpressLRS Version
LED Status	Protocol Version
Red Flash once	Internal ELRS
Purple Flash Three Times Quickly	Internal TX Module Off and Run External TX Module

Note: LiteRadio 3 Frsky version only works with D16 ACCST 1.X Frsky protocol. So if you use a Frsky receiver with D16 ACCST 2.X version or ACCESS version, the binding will fail.
