Hello, the problem I have is that when the M95 is connected to the internet, after some time the GPRS is deactivated, this is normal or I am incurring some configuration error.
Below I list the AT commands that I am using to connect to the internet, I appreciate your help in advance.
If there is no data transmission on the TCP connection for a period of time, it will release the port to other connection to achieve a rational allocation of port resource. So the TCP connection between the module and the server may be disconnected by GPRS network without any notification. Please refer to the attached document for TCP connection maintenance and detection ways. Quectel_GSM_TCPIP_Recommended_Process_V1.2.pdf (950.7 KB)
The issue can be related to the network and we need to analyze chipset logs for network-related issues. Could you please send an email to support@quectel.com to get Chipset Tool and please provide us chipset logs?
