I know this is a very old thread, but we're using some FM1120 and we're still experiencing many freezes on the devices. I would say that after 2 months the 25% of the devices got stuck.
We're using a very new firmware, version 01.14.04, but still experiencing 2 major issues:
- After remote firmware update or configuration upload, devices freeze
- Same freeze at random time.
When device freezes, it doesn't register to the GSM network, so there's no other way to just power cycling the tracker in order to fix the problem.
I read that all those freeze issues had been fixed many years ago, but not really sure.
Is anybody still facing freeze problems?
We saw that configurations with deep sleep enabled are more affected to freeze issues....
