Is there Integration support for EdgeTX when running Express LRS? I see the Integration support for FrSky F.port and S.Port but not for ELRS.

well, elrs is the protocol between transmitter and receiver.

until recently elrs receiver used exclusively CRSF from receiver to flight controller (or sprit in this case)

Thomas said here: viewtopic.php?p=37415#p37415

that he is working on CRSF for the spirit.

and here is the result:
https://manual.spirit-system.com/index. ... sFire_CRSF

so transmittig to the unit should be working.
since opentx and edgetx are related, the support for telemetry and scripts is probably a hit and miss..
sorry did not test myself so can not say for sure.. (after fiddling around i stayed with jeti for spirit and edgetx for my quads..)
