Here the regulations for Switzerland which are pretty much tracking EU requirements: https://www.ofcomnet.ch/api/RIR/1008/09 More frequencies: https://www.ofcomnet.ch/api/RIR/1008 2.4GHz data transmission: https://www.ofcomnet.ch/api/RIR/1010/01 Or the more restrictive version: https://www.ofcomnet.ch/api/RIR/1008/11 Seems like on 869MHz...

Cept regulations are here: For generic short range devices: https://efis.cept.org/adhoc_grabber.jsp?annex=4 And for wideband data transmission: https://efis.cept.org/adhoc_grabber.jsp?annex=6 Actually pretty identical to the swiss documents above, as those are a national implementation...

@valfa14 I was looking into jeti but ended up with a TX16S instead. Would have loved spending my money with a European brand, but it was not within my budget...

The AT86RF231 is a: High Performance RF-CMOS 2.4 GHz Radio Transceiver Targeted for IEEE 802.15.4™, ZigBee®, 6LoWPAN, RF4CE, SP100, WirelessHART™ and ISM Applications As per the product page: https://www.microchip.com/wwwproducts/en/AT86RF231 It...

@kilrah that's for sure true for fasst(est), but I think t-fhss is a cc2500 protocol and thus feasible if someone can produce the SPI traces??

Unfortunately I couldn't find any t-fhss gear on second hand market, especially not in any sensible budget. Else I would have got a set to play with the logic analyser,...

Hmmm strange way of assigning the channels to the outputs... It actually needs support by the TX: https://www.rcgroups.com/forums/showpost.php?p=44091981&postcount=227 I guess someone with a working flysky setup would have to capture...

As it seems purely ibus related it might more be an issue to best be tackled by edgeTX/openTX maybe even a LUA script?

Do you have the equipment? Then you could spy at ibus while binding the cev04. It seems ibus is a noninverted 115k2baud serial bus: https://www.arduino.cc/reference/en/libraries/ibusbm/

Thanks for your reply. I cloned your repo to here: https://github.com/diego0815/DIY-Multiprotocol-TX-Module/tree/SX1280/Multiprotocol with the purpose to try playing with the SX1280 to emulate other RF components, not sure if it's feasible...
