Hi Team,
I am currently using the A7672G GSM module and experiencing some issues. When I turn on the GSM module, the power sequence sometimes doesn't change. Additionally, I've observed that the GSM module restarts automatically, even when it's idle. Could someone help me troubleshoot and resolve these issues?
