"I placed a Diode in series with the APM and the XBee power lines. CTRL-T is working now but with a lot of packet loss: After some time the data stops flowing through. Led light in XBee on on APM side."

"Control/T does not work for me unfortunately I tried various setups today: *Use UART0 hard wired *Disabled XBee CTS on APM side *Changed my Adafruit XBee Adapter kit [v1.1] on the PC end by the XBIB-U-DEV *Swapped the Adafruit XBee Adapter kit…"

"Did you finally where able to solve this issue? I'm having the same issue with Arduplane, APL2 and the XBEE 868MHz radio's. I can't get the telemetry working wirelessly."

"Great, after reversing all controls in the configuration screen of the APM planner 1.1.95 mav 1.0 it works great! Thanks for your help! Hessel"

"Thanks for the settings file and the cfg for XPlane 10. I will try this tonight. I had some issues getting my new PC up and running the past few days."

"I installed the APL planner on a clean PC (updated to the latest version) and loaded the HIL firmware. Then I connected the autopilot and saved the parameter file with the default settings. I will let you know the results after i tried this setup…"

"You can try loading the firmware again. It seems to reset the parameters."

"Great stuff. I wanted to start with the simulation but I can't manage to get the APM 2.0 with ArduPlane? V2.40 HIL firmware controlling the plane in X-Plane. I'm using the xplane_PT60.param file in the APM planner. I can fly the plane…"

"Did you use version 2.5_01 ?"

"What was the power setting of the XBee's ?"

"Apparently the wind was blowing from the NW"

"Great work, I'll give it a go !!"

"What are the limitations of the V1 shield I have v.s. the new V2 shield ?"

"How are the following SBAS parameters of the U-Blox5 GPS reciever configured before shipping ? Mode - SBAS Subsystem Mode - Allow test mode usage Services/Usage - Ranging"

"It looks like the UBlox5 can also do I2C through the DCC port (one way only)."
