RSM devices support
To support remote speaker microphone (RSM) devices, T.Flex PTT media button behavior must be switched to RSM-compatible mode:
- Enable Use HW intents in T.Flex settings.
- Tap Select HW intents.
- Tap PTT by media button.
- Select Use RSM (mode 1) timings.
Google Assistant or audio players running in the background may cause T.Flex not to respond correctly to the PTT button on the connected RSM device.
