Hi, we’re using the Raspberry Pi 3G-4G / LTE Base Shield V2 with a Mini PCIe EC25-E module. We connected the shield to the raspberry using the USB connector and we verified that the system works well. It was not possible to activate the V2 shield using the AT commands (header pin). Please, could you explain to me if it is possible to check the shield using the AT commands?
If so, could you send me a sample code and information about it?
Thanks in advance
The Shield is not connected to UART by default. In order to use UART you will need to bridge the UART RESISTOR pads available below the Shield.
While using ttyUSB3 for internet connection. you may use ttyUSB2 for AT commands.
