Raspberry-PI LTE Setup

To set up LTE connectivity on a Raspberry Pi using POI and minicom, follow these steps:

  1. Open Minicom
    Use the following command to connect to your LTE module:

    minicom -D /dev/ttyUSB2

    Then enter the following AT commands:

    • ATE1 (Enables command echoing)
    • AT+CGDCONT=1,"IP","super" (Configures the APN)
    • AT+COPS? (Checks the network operator; the output should resemble: +COPS: 0,0,"Vodafone UK Twilio",7)

  2. Close Minicom
    After receiving the network operator details, close the terminal window.

  3. Activate the PPP connection
    Run the following command to establish the LTE connection:

    sudo pon

  4. Disable Wi-Fi
    If needed, turn off the Wi-Fi interface to ensure the LTE connection is prioritized:

    sudo ifconfig wlan0 down

With these steps, your Raspberry Pi should be connected to the LTE network via the POI setup.
