Hello all,
I’m using GSM(EC200S-CN) modem for connecting GSM. For checking network, I’m performing AT command (gsmcmd at+cops?). It is operational and responding this AT command.
I’m putting the modem ideal for long run(almost 24 hours). After 24 hours AT command (gsmcmd at+cops?) are not responding. Means the output of the same command is blank as below:
[2023-07-19 10:20:38.437] gsmcmd at+cops?
[2023-07-19 10:25:58.629]
Sometimes, the output is ERROR. Below FYR:
[2023-07-18 15:59:45.506] gsmcmd at+cops?
[2023-07-18 15:59:51.071] ERROR
Key Points:
- Fixed and steady setup for GSM(EC200S-CN) modem throughout the long run. [E.g., location/device/harness/power supply(12V)/internal battery(4.1V) are constant].
- There is No power fluctuation or power interruption happened throughout the long run. [Tested]
- Ideally kept for long run.
How to recover GSM modem here to operate and make it operational? Request to share solution/feedback.
Note: Anyway, to restart/reload the GSM modem from application/firmware so it can work continuously? Is it good idea or any alternate way to resolve GSM modem hang issue?
