I saw that you didn’t answer “Q2686 not responding” topics but I want to ask again.
We desing a car tracking kit using Q2686 Wireless CPU. There are about 1000 kits at field, and 10% of them freezing after a while. So we need to service for them to power off and on.
They drop from GSM, not respond to any AT command.
We tried to update firmware but it doesn’t work.
Are there any solution for this issue from your side?
