Setup to use 4G Module

• Simply connect breakout to PC/laptop via USB Type C.

• Now press, hold Power Key button and release after 3-4 seconds to activate module. LEDs associated with the network will light up, first NET_STATUS then NET_MODE will be on and finally NetLight LED starts blinking. This confirms module ready for use.

• To verify open device Manager and check if below listing you can see into COM port. If you cannot see device then driver is missing, download and install driver from here

  

• If everything goes well it will connect as a cellular network in your system as shown below. After the succesfull 4G Module connection you will able to use your cellular network to connect with internet.

  

For AT Commands Testing

• Open XCTU software and select the Serial console option to run as shown below.

  

• Select Configure option and then suitable AT COM port. Change Baud Rate and other details only if needed, for the 4G module we will keep default settings. Select OK and After that just Close the connection to start.

  

• Now the 4G module is ready to accept AT commands for testing. Either you can send commands through console log or create packets to send AT commands.

  
  • AT
  • AT+CPIN? You can refer to the manual for more such AT Commands

• Creating packets is a good option for multiple commands testing. Don’t forget to add 0D and 0A required for carriage return and enter.

  

Interfacing with MCUs

• Pico and Breakout interfacing

  Pico	4G Module	Function
  GP0 (TXD0)	RXD	UART Communication Pin
  GP1 (RXD0)	TXD	UART Communication Pin
  GP22	PowerKey	Module Power Key
