No CRSF Extended Limits in 12 FULL Midex configuration

[sdellava]

Current Behavior

The tx is set to 12 Full Mixed at 333 KHz. The rx (BETA FPV 5 CH PWM) is configured with the two channels at 333 Khz.

According the manual, I should have a PWM from 885us to 2115us, but this is what I have on the PWM output.

So the range is a "normal" 900-2000uS.

Steps to Reproduce

1. Configure the 12 Full mixed mode at 333 KHz

2. connect an oscilloscope to the PWM output

Your Environment

• TX hardware: BETA FPV 1W external module
• RX hardware: BETA FPV 5CH PWM
• Handset model:
• OpenTX version (including nightly number): EDGETX 2.9.1
• ExpressLRS version (TX & RX MUST MATCH): 3.3.3
• Packet Rate: 333 Hz
• Telemetry Ratio: 1:128 (telemetry dsabled)
• user_defines:

Extended Limits are working fine for me. Just enable EdgeTX "Extended limits" and set channel min/max to -120/120.

@Mkorho thanks for the explaination. That's sound interesting, but I really can't find how to "enable EdgeTX Extended limits" in my model setup. And actually I can't find any detailed documentations.

Even googling I can find only some reference in the Multi-Module documentation that is not relevant in my case.

Can you drive me in the right directions? Thanks

@Mkorho thank you very much. It was well hided :).

I suppose that once I've enabled this flag, I need to extend to -150/150 all the channels that really need a 10 bits encoding, so for sure the AUX0, 1, 2, and 3. Am I right?

No, ExpressLRS only supports -120/120 extended limits.
