Interesting problem with OpenLRSNG

[sgofferj]

Hi,

I got myself a Hobby King OpenLRS kit and flashed OpenLRSNG 3.0. Then I configured OpenTX to output 12CH PPM. OpenLRSNG is also configured for 12CH. On the receiver, I have channel 1-8 output in a PPM stream on pin 6 and pin 2-4 output channel 9-12 as PWM. The PWM channels work smoothly. However, when I feed the PPM signal into my APM, I have the following issue:
If Ch5, 6 or 7 is > 50%, then suddenly all channels are one number off. That means, transmitter channel 5 arrives at the APM as PPM channel 6. Transmitter channel 6 appears on the APM as PPM channel 7, and so forth.

Does anyone have any idea what might be the reason for that problem?

what PPM frame lenght did you set when setting the number of channels to 12??

OpenTX chose automatically 30.5ms, 300µs, -
I didn't change that.

sgofferj, you may be experiencing a problem that was found in 3.0. it should be fixed in 3.1.

It is fixed. I updated today and tested and it works. I found a bug in OpenTX, however, but I open a new thread for that.
