Hey Mecil,

Pardon the delayed response. If you are still seeing these issues. Are you able to properly connect to the daemon still? or does the daemon also fail. If both fail, next try directly connecting to the serial port of the arduino device (you can use Arduino IDE serial monitor, putty, etc.) and seeing what the device transmits if you type

AT+HELP

Best,
