Recomended SR values for telemetry throught RFDesign RFD868x radios (TXMOD V1)


I´m using a RFDesign RFD868x link for telemetry an d rc control.
Land side radio is integrated in a RFDesign TXMOD V1 device with SPort hack made.

In addition to MAVLink (V2) telemetry, this link is also used for SBUS RC control.
All seems to work quite well but i would like to know wich SR Values are recomended for this type of telemetry link.

Now my SERIAL / SR setup looks like this:



Radios BaudRate are set to 115200 and Air Rate to 200.

And this is my FC data:


Thanks in advance.
