Frsky Telemetry with BB Blue about ardupilotblue HOT 11 CLOSED

@ninjatrent Hi, FrsSky Telemetry will not work out of the box. You have to invert RX and TX and put them together

from ardupilotblue.

My apologies for I don't understand. Can this be done by connecting RX to RX and TX to TX on BBB and the RX and TX wires connected?

from ardupilotblue.

Did you get it working? did you figure out the connections?

from ardupilotblue.

No sir. I was unable to find a solution to this issue.

Hi @mirkix , here is what I did

1. Mapped Uart 5 in beagle bone to Serial 5 in Ardupilot
2. Configured Serial 5 to 10 'Passthrough'
3. Inverted Tx and Rx from within Ardupilit
4. Connected the Tx wire to the Signal Pin in the S-Port in R9 Stab receiver
5. Connected Tx and Rx together (short circuit)

Then in the transmitter I started 'Discover New Sensors' but no data came.
Do I miss anything?

Any progress on this?

@dziedzic99 Did you manage to find any additional info on how this can be done?

from ardupilotblue.

@RedgarTech Response time from BBB is simply too long and it times out. Probably due to the OS standing in-between. Having some more experience since a year ago when I tackled this matter I highly recommend switching to ELRS and moving away from Frsky.

@dziedzic99 here's the thing, I found someone here

[https://discuss.ardupilot.org/t/connecting-rx6r-or-r-xsr-to-beaglebone-blue/91963] (Frsky Receiver Ardupilot Discussion)

who found a way for it to work. I am attempting to get it working now actually.

Also, did you eventually get Frsky working?

Hi,

I have sucess on this, but with black. I detected some issues with receivers, Beagle ports demand at least 3.0 volts do be detected as high, so the Inverted circuit I'm using is generating 3.3 volts and is working fine.
This for PRU too - I have several R161 receivers and this is generating sbus signal with 2.65 volts and this is not detected by the beagles, I had to use a shift level circuit to increase to 3.3 volts to get this working too.
