Hi all,

We have just finished building our hexcopter on Wednesday. We are using the NAZA M V2. On Thursday, we took it out to do some motor testing - we did not take off. We conducted a motor test through the NAZA assistant software and set our U channel 3-way switch to manual, ATTI and GPS. All good and the LED showed the changes respectively when we flipped the switch back and forth.

Today we decided to see if we could get our CSC working - which we finally did after tweaking our end points and subtrims - and found by pure chance that there was no GPS option under the U channel in the NAZA assistant software. Sure enough, when we flip the switch back and forth we only get the yellow LED of ATTI mode.

Help! One day it was there, the next its not. We have checked the Plugs, everything plugged in, unplugged, power cycled, plugged in again. Still nothing.

Any ideas guys? It seems that just as we get one thing working, something else decides to go up in smoke.

Cheers George

Hi,
It seems that the A2 can not recognize the GPS module, could you please try below steps to see if you can fix it? If it doesn't work, please return it for repair.

1) short-circuit the F1/F2 ports via a 3-PIN cable (see below picture).
2) Connect to main controller to the assistant software as usual. Click “upgrade” and the system will download new firmware automatically.
3) After the download has been completed, please pull out the 3-PIN cable and then click “upgrade” again. Otherwise, upgrade will fail.
4)Upgrade successfully and import the configuration which you have exported before
