Is there support for this serial protocol? I see SRXL, but my understanding is that SRXL2 is different.
Im running out of options for my friends Spektrum xmtr to interface to the flite cntlrs.
There are no more sources for S.bus format, which is what I usually use.

A quick scan of the source code shows SRXL, but not SRXL2.

In case this helps, you mention the transmitter in regard to this.  I see that SRXL2 is indeed a receiver output protocol, but if you are mainly interested in using the transmitter, perhaps you can use a different receiver that outputs something that LP can use.

If I might suggest, it looks like Ardupilot supports SRXL2.  Ardupilot seems more actively developed than LibrePilot  :( .

Ardupilot says: "All Spektrum receivers released since August 2019 only support the SRXL2 protocol."
I would add that any receiver that you can plug a set of standard (analog or digital) servos into supports PWM (the standard, one servo per wire protocol), which LP does support as long as your receiver has a set of servo (PWM) outputs, and your flight controller has a set of PWM inputs.
