Hello, I am using the raspberry pi cellular iot application shield, the module is BG96. I am pretty sure it is connected to the Internet. I connect it with my pc. But I cannot have the access to the debug port /ttyUSB0, when I use mobileinsight to monitor it. It will return the error
PHY COM: /dev/ttyUSB0
PHY BAUD RATE: 115200
device reports readiness to read but returned no data (device disconnected or multiple access on port?)
Does anyone can help me?
