RC7620 data mode to command mode ,without restarting the GSM module

IoT Modules RC76
1

Currently, I am using the RC720 GSM module for data communication. The module collects data every 1 second and transmits it to our local server via the UDP protocol. However, sometimes the GSM module does not exit from data mode back to command mode after the data has been fully pushed to the server. In such cases, I am forced to restart the GSM module, which consumes significant time and creates conflicts with my real-time cycle requirements.

I would appreciate your support in finding an alternative solution to handle this issue, so that the module can reliably switch back to command mode without requiring a full restart.

Which AT commands are you using for sending data?

If you are using +kudpsnd command, The data session can be ended by , +++ or DTR.

Have you tried to use ppp dial up with host platform so that your can send data by host MCU?

Have you tried +++ or DTR pin?

5

or +++ before 1 sec guard time needed, and DTR pin I have not tried yet, please explain little bit more about DTR pin

6

Then is it +++ working for you?

For dtr, you need to first check at&v for the &d value

7

+++ is working but it also takes the same time

Can you please send me the procedure for implementing the DTR?

What is the return of at&v?
Are you using uart?
