So in the /etc/default/arducopter file you can set the telemetry options but I was hoping to find some more information because I am looking at forwarding Mavlink data from the GCS through a USB port on the Navio2 to a second raspberry pi.
In the options menus you have your TELEM# options like so:
We set our radio to 115k baud rate and it seemed like the way to do this was to set our second telem as an “-A”
TELEM2="-A /dev/ttyAMA0" since I wanted to use the UART port on the Navio2 to connect our telemetry radio with. However now I want to have telemetry data received by the radio on TELEM2 to be sent to a USB port to be forwarded to a second raspberry pi.
This leads to my system not connecting to my GCS. So I have a question as to which Telemetry is what Serial# in the parameters list?
Is it based on the lettering? like:
“-A” is for Serial0,
“-D” Serial 3
“-E” Serial 4
In that case how would i set a Baud rate besides my default one for that option as it says that “-A” is 115k baud rate while “-C” is 57k
On another note, how would I then get this mavlink data forwarded out the USB port.
I noticed in Mission Planner I have a Serial_PASS1 and Serial_PASS2 option so if I set one serial port as the input from my radio module and the second as my USB port would that forward the telemetry data out that USB port?
