LTE Cell Modem (Quectel EG25-G)

The Summit SOM 8M Plus DVK features an onboard Quectel EG25-G Cat. 4 LTE cellular module which can be used simultaneously with the Wi-Fi and Bluetooth available on the SOM itself. The Quectel EG25-G is supported and managed by ModemManager

Inserting the SIM Card

The Summit SOM 8M Plus DVK supports the nano (4FF) SIM card form factor, and the slot is located on the underside of the main PCB at CON9.

Powering on the LTE Cell Modem

The LTE cell modem is powered off by default. To enable it, enter the following command:

modem on

Now, the LTE cell modem will boot up and enumerate with ModemManager. Standard ModemManager/NetworkManager commands can now be used to bring the cellular connection online. Check with your cellular provider for the appropriate connection settings (e.g., APN).

Additionally, the modem can be disabled again with the following command:

modem off
