    TEL0179-Functional Diagram

    Interface Name Description
    ANT Primary antenna interface, connects to GSM antenna
    UART UART interface (interface level 3.3V-5V)
    USB-typec USB device interface for communication and parameter setting with computer
    Power IN External 5V-12V power supply is required when using UART interface
    NanoSIM Card Insert SIM card

    Precautions:

    1. External 5V-12V power supply is required when the module uses PH2.0 socket for serial communication
    2. Net - Network signal indicator light
    • Blue light on for 0.2 seconds, off for 1.8 seconds: searching for network
    • Blue light on for 1.8 seconds, off for 0.2 seconds: standby state
    • Blue light on for 0.125 seconds, off for 0.125 seconds: data transmission state

    Note: This status prompt only applies to successful PPP dialing or AT command active PDP activation, successful RNDIS networking

    1. Short-term output of log information and debugging information during boot process
