I did a search on Google and imo Futaba is not sending RSSI. There are several blogs how to take the RSSI signal form the receiver CPU. I like to hear if there are others using Futaba SBUS and don't see RSSI.
Yes, I am using the Spectrum port.
Well the radio is set to 14 channels (Multi in Futaba), but I can only see 8 in the Groundstation, so 14 channels are sending.
Yes the receiver is on , groundstation RSSI '0'
If I turn of the radio the RTH kicks in, so I am not affright for the zero rssi.
I made the converter myself: http://autoquad.org/wp-content/uploads/ ... verter.png
But I am not powering the receiver by 3v3, I use a spare channel on the receiver to feed it with 5V. I do this because 3v3 is on the limit of the receive and if there is a power dip I am loosing it.
Oke, will log it and look back.
Let me know if I need to do something else.
