rssi on sbus like xm

[mrakca]

Hi,
short nooby question, what is needed to implement an artificial channel on sbus representing current rssi?
Like the XM is already doing, I guess the microcontroller somehow measures the rssi pad of the CC25XX chip and builds it into the sbus stream.
if the microcontroller communicates with the radio chip over spi, is it possible to read the rssi too?
I hope that this feature is possible just with just a small modification on x4r-ii

best regards!

It is already implemented. See SBUS channel 9 ;)
