0 USB and the telemetry port Posted by Julie Macfarlane on January 12, 2011 at 6:47am Can an Xbee be connected to the system at the same time as trying to use the serial port for CLI use? You need to be a member of diydrones to add comments! Join diydrones Email me when people reply – Follow

Ok. The USB is serial1 and the Xbee is Serial3.
I have the Serial3.OUT of the APM to the Sparkfun IN and visa versa correct?
Serial data goes out from APM over one or the other I believe.
You can definitely leave XBee connected while also connected to USB.
I upload code over USB, and configure over XBee.
Make sure you have it at 115200 with carriage returns turned on
Ok what I see, with or with out the Xbee attached is:
1) switch to the pins side, LEDs a/b/c walk.
no response from the Arudino serial monitor
2) With the switch forward LED A green and stable
I get a single string of text (garbage) with no menu.
