basic problem i am having is that my Telemetry setup wont communicate with my APM.
- (2) Xbee Pro 900
- https://www.sparkfun.com/products/9097 (on aircraft)
- Sparkfun adapter for computer
- Sparkfun adapter for Aircraft
- APM 2.5 board
- Mission Planner 1.2.67
- init ArduCopter V2.9.1b
My first problem was that the Xbee would not even communicate with themselves before ever connecting to the APM. Turns out that if you have the "Xbee explorer adapter" from sparkfun you have to edit your Xbee firmware to correct pullup resister parameters (this is a whole other issue). Once i fixed that i was able to have my Xbees range tested and all worked out correct. I connected my APM to the PC via usb and made sure that my firmware and updates are ok and all went fine. The problem is that when i connect my Xbees to the APM @ 57K at the correct port (USB is not connected so not to conflict with telemetry) it wont connect. My Adapter board on the PC side has LEDs (TX/RX) that don't light up indicating to me that there is nothing coming from the mission planner software to even try and connect. Have I missed something that needs to be configured on the Mission planner side that i have not realized? I am at a complete loss.
