Couldn’t connect to Quectel EC25 Modem on Jetson Nano

I’m trying to connect to Quectel EC25 on Jetson Nano. My Jetson Nano detects the modem. When I command “sudo modem-manager.mmcli -L”, the output is " /org/freedesktop/ModemManager1/Modem/5 [Quectel] EC25".

However, it doesn’t connect when I run the Python line: “sock.connect((, 9696))”.
Can the problem be caused by the port or IP address? Because I’m not sure I must use those port and IP address. How can I get the port and IP address of the modem? Thank you.

You need to dial first, and then use the dhcp tool to obtain the IP address from the module.

Thank you for your response. Can you explain to me how to dial it?

You can use quectel’s quectel-CM tool to dial and establish a network data conection.
