Hi, Chy,

Same thing with mine.. 

My quad flies great, everything works as expected... 

I've connected serial3 from APM to FTDI-USB to PC, and it works fine. 

In qgroundcontrol i do get an connection , but lots of garbled data.

I've tried 57k6 and 115k2 , no difference.

My Xbees are the PRO S2B rev. B, the one connected to pc is configured as Coordinator AT, and the APM XBee as End device AT.

This was the only setup i could get a connection with...

best regards, Kiki

Last night i wanted to do some tests, but one of my XBees died... 

can't read or reprogram the XBee with x-ctu, lights do light up, link is established, but no data transfer.

I think the crc errors where already a hardware problem in 1 one my xbees, and now it completely died..

but no problem, cause i ordered 2 XBee Pro 868'es. (range up to 40KM!)

i'll let jou know if they work as expected or not..

Maybe my Xbee's are too died, isn't it ?

I'll order some XBee S1 I think, because S2 are too complicated for what I want to do ...

Is it possible to use them with a serie 1 firmware ?

We could test if the problem is an hardware problem or just a firmware.

So its definetly a HW problem...

My Xbees are now working in both ways, but I get something like that :

"

U8

"

So I think there's a problem.

What should I see ?

I received my new XBee Series 1, I have the same problem : When I try to connect with APM Mission Planner I have this :

"INFO ArdupilotMega.MAVLink - lost 31 pkts 284
INFO ArdupilotMega.MAVLink - MAVLINK: S wait time out btr 0 len 0
INFO ArdupilotMega.MAVLink - MAVLink readpacket read error: Timeout
INFO ArdupilotMega.MAVLink - Mavlink Bad Packet (crc fail) len 0 crc 65535 pkno
0"

And it says "Connect Failed" but I have some heartbeat because it says before : "getting params [...]"

I'm going to be crazy and It have to work for next monday ! Can some people help me ?

I have just created my own quad and am using an apm 2 and a spektrum dx8, AR7000 and TM1000 telemetry module. I couldn't get an xbee connection at all.

This was strange as I regularly fly an aircraft with arduplane and xbee's pro s2's and a futaba tx with spektrum module, a spektrum AR7000 receiver in the aircraft and that works fine.

Finally in desperation, I removed the receiver & telemetry module and tried that, success, it connected but was still losing some packets. There seems to be an interference issue with 2.4ghz, haven't worked it out yet if it is my router, phones or what.

Turned out to be a faulty receiver, works fine with a new one.

Hi Chydra,

 

What's news ?

Best regards

Hi bypbop,

I tried some other tests, and I now have a reception from the drone to the Ground Control, but I can't send something to it, so I can't connect with APMission Planner but i can see the virtual horizon and the parameters (read only) with QGroundControl.

Best Regards
