OK, cycling battery out/battery in a few times perhaps made the 22M regret its stubborness to accept the firmware upgrade. No more endless clicking when the Z f is switched off.Yay. However, the M still refuses to connect to any of my BLE GPS units. It "sees" them and I get the message 'tap to pair'...

The really odd thing is that the battery-draining behaviour had disappeared after my first upgrade to the latest firmware. It only returned after I had done a factory reset, *then* updated firmware again?? I have no idea what is going on here.

Nearly 2 months have elapsed and the 22'M still does not work. I became frustrated with all the troubles and followed the instructions to reset the M to factory defaults. Then updated firmware to the latest version. Now, we are back at the beginning of this sad story -- again. Despite the updated f...

After more attempts to get stuff working, either on the Z f or the Z fc, nothing works any longer. All functionality has broken down. The app intermittently "discovers" the 22'M, once in a while it allows me an attempt to connect either the Qstarz or the GL-770M, but they never connect after I have ...

This getting weirder and weirder? On the Z f, I can occasionally get 22'M to cooperate with the GL-770M. The GPS disconnects ever so often, then gets connected again, and GPS data is recorded. On the Z f, the indicator LED alters between red and turqoise all the time? I haven't tested yet whether I ...

Unfortuntely, any improvement is very hard to verify, as the 22'M keeps disconnecting all the time. Camera Z fc. I have updated the firmware to A3.1.2 etc.

Oh well. One step forwards, perhaps one or two backwards? The firmware of M'22 has been properly updated to the latest version : A 3.1.1, B/C 3.10. The battery drain when the camera is switched off seems to be gone. Tested overnight with my Zf. That's positive news. On the other hand, it is apparent...

Updated my Unleashed app to 3.02. No deal. The drive light of my Z fc blinks merrily as before, as soon as the camera is switched off. It stays that way until the battery is completely drained and the camera dies.

You did nothing wrong, but relied on information that later has proven incorrect and misleading . The 22M cannot geotag with Z50, or in my case, Z fc or Zf. If your main purpose is geotagging with the Z50, use the free Snapbridge app instead.and use it only for getting location data. I'm also disapp...

Update:

HDMI cable plugged in, M off its magnetic plug, card in camera, camera switched off: no battery drain over night..
HDMI cable plugged in, M sitting on its magnetic plug, card in camera, camera switched off: dead battery in the morning.

In both cases no Unleashed app running concurrently.
