Hi
My setup is as following:
APM 2.0
XBee-PRO 900 extended range module w/ RPSMA connector (Laptop Side) XBP09-DM Firmware 1061
DIYDrone XtreamBee USB Adapter (Laptop Side)
XBee-PRO 900 extended range module w/ wire antenna (APM 2.0 side) XBP09-DM Firmware 1061
DIYDrone XtreamBee Board (APM 2.0 Side).
- I’m able to successfully test Airlink between the two XBEEs using X-CTU and loopback.
- I’m able to receive test text over the air link when I use serial testing sketch on APM2.0 board, connecting the XBEE to the side UART0
- I soldered the UART0/2 MUX jumpers on the bottom of APM 2.0 to select UART0
My 1st Issue is I’m not able to see any signal on the back UART0 connector even when I load the serial test sketch which is giving perfect output on the side UART0. Is this a known bug in APM 2.0 board ?
My 2nd Issue is that I’m not able to establish telemetry over the airlink, I tried 57K & 115K baud rates, I tried HKGCS & APM Planner but no luck (Even when using the long side UART0 port)
Please help me.

Chris,
UART0 is as shown, no need to change the wiki if the issue is not common.
Muthanna,
I'm not sure I'm following. Where is the UART0 that you're referring to? The images in the wiki refer to the standard setup, which is what I use.
Maybe some boards shipped from the factory with a missing/broken microtrace for the UART selection? If so, we'll correct that. But I'm not understanding why the manual recommendations should change, since that's what thousands of people already use.
Chris,
APM2.0 photo you just posted has Ver 2.4.1 on it, mine is Ver 2.4 (I bought it from 3DR almost one month ago); is there any difference related to our issue ??
