Newly selected serial protocol is only output after power reset

[mha1]

Current Behavior

Using the LUA script changing from CRSF to SBUS will output SBUS protocol on the receiver's TX pin instantaneously. However changing back to CRSF in the same session continues to output SBUS protocol, not CRSF. After power cycling the receiver CRSF protocol is output.

Steps to Reproduce

Example using RM ER6 on 3.3.2 with module also on 3.3.2:

• put logic analyzer on the ER6's JST TX pin.
• power radio, power receiver and wait for connect
• observe CRSF serial data on JST TX pin
• open LUA script on radio, go to the receiver page
• change to any other serial protocol, e.g. SBUS
• observe brief link loss and reconnect
• observe SBUS serial data on JST TX pin
• change serial protocol to CRSF
• observe brief link loss and reconnect
• observe still SBUS serial data on JST TX pin
• power receiver off, then on again, wait for reconnect
• observe now correct CRSF serial data on JST TX pin

Your Environment

• TX hardware: Radiomaster TX16s/internal ELRS, Flysky NV14/external BetaFPV micro module
• RX hardware: Radiomaster ER6
• EdgeTX Version: 2.9.3
• ExpressLRS version (TX & RX MUST MATCH): 3.3.2 ISM (also in current Master)
• Packet Rate: 100Hz (but doesn't matter
• Telemetry Ratio: 1:8 (but doesn't matter)
• user_defines: standard
