Connection Error in APM Mission Planner with wireless telem
Earlier today I had the Mission Planner communicating perfectly with the APM (1.4). But now when ever I try to connect the usual window comes up and says "Getting Params.. (sysid 1 compid 1)". Then that stays for roughly 30seconds then I get "Connect Failed"
What is really interesting is that when I use HK GCS it connects no problem.
I do have the baud at 57k and I have run the X-CTU on both XBees and everything seemed good there. What else should I try?

1. does it connect via usb? this will indicate a firmware issue or not.
2. HK's gcs does not require you to have a paramater list, this is why it will connect. My thought is that your rx line is working, ie receiving data, but your tx line is not, as when the planner requests the data the data isn't getting there.

1) It does work via USB. btw I am using the 2.4GHz module and baud of 57600
2) When I try to connect I get the message I mentioned then there is a details section which reads
---
Timeout on read - gerParamList 0 5
Your serial link isn't fast enough

How do I check whether both Xbees are transmitting and receiving?
I am also a little confussed on what is meant by requiring a parameter list. When I connect via USB I can go to configuration and read/write params.

check your cableing, your rx line on your apm is not getting a signal.

I have exactly the same problem with a bluetooth module, I get the led lighning, but can´t get data back.
and after 30 seconds it crashed.
Over USB it works perfekt.

So I won't claim that the following is a solution, it is merely the last thing I tried before it started working. It may be unrelated.
AMP>>Config>>Planner
Then I turned all the data transfer rates (attitude, position, etc...) down to 1Hz and tried to connect. Connection worked. Then simply turned the rates back up to desired. Seems to be working.

Tried your solution, but i have to do it everytime i have power up the system.
Also this is only a issue when i have arduplane v2.33 loaded, have tried with arducopter without any problems. so i think its a fault in the arduplane code.....

Djalma, your issue apears to be cabeling. as the mp sends packet to the apm, but isnt receiving them.
