• AT Command
  網路說能用mmcli下ATC, 但要開啟debug mode
  

  $ mmcli -L
  /org/freedesktop/ModemManager1/Modem/1 [Cinterion] Cinterion PID 0x00B3 USB Mobile Broadband
  

  
  Test with normal mode

  $ sudo systemctl restart ModemManager.service //make sure it's running
  
  $ mmcli -m 1 --command="at"
  error: command failed: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Unauthorized: Cannot send AT command to modem: operation only allowed in debug mode'
  

  
  Switch to Debug mode

  $ sudo ModemManager --debug
  

  
  Test again. Don't be sudo and must enter Upercase

  $ mmcli -m 1 --command=AT+COPS?
  response: '+COPS: 0,0,"Chunghwa Telecom",7'
  
  $ mmcli -m 1 --command=AT^SMONI
  response: '^SMONI: 4G,3050,7,20,20,FDD,466,92,2E19,3454A18,194,19,-105,-12,,NOCONN,,,7,--'
