Serial protocol for TX-Modul (instead of ppm)

Post by wilopaan »

Hi all,

I am looing for information about the serial protocol that is used to communicate with the TX-module, e.g the PascalLanger Multiprotocoll-TX-Module

1) Is there any documentation about the protocol beside from the sources?
2) Does the TX-Module switch atomatically from ppm to serial mode (if it detects the data on the tx pin?)

Thanks for any hints!

It's SBUS with 2 extra bytes for config and protocol selection. Don't think there's doc besides the code.

No it doesn't switch, you need to select 0 on the rotary selector when there is one for serial, the other positions are different protocols with PPM in. If a module has no rotary selector then it only supports serial in.

The protocol is fully described in comments in "multiprotocol.h".
