@ -33,6 +33,11 @@ If your module is always/sometime binding at power up without pressing the butto
- Arduino Pro Mini with an external status LED: to work around this issue connect a 10K resistor between D13 and 3.3V.
- 4in1 module V1 (check 4in1 pictures): to solve this issue, replacing the BIND led resistor (on the board back) of 1.2K by a 4.7K.
FrSky & SFHSS bind issues are ususally due to Option=fine frequency tuning not set properly. This value is different for each Module. To determine this value:
- find a value where the RX accepts to bind. A good start is to use one of these values -40, 0 and 40.
- find the values min/max where the RX loses connection. In serial mode you can change the value and see the effect live.
- set the value to half way between min and max.
