Hi, I am successfully using the SODAQ NB-IoT Board, receiving e.g. temperature / humidity data via the All Things Talk Platform using the example (Arduino) programs.
However, the connection is only established and data is only sent after I hook up the board to my PC, open the Arduino IDE, upload the program(s) if not yet done and activate the serial monitor. In any case, I must open the serial monitor. From that moment on, the board tarts spitting AT comments, the connection is established and the data is received.
If I take the USB from my PC, add a 5V adapter to it and put it in the electrical means, itdoes nothing. I should expect that the Arduino should reset and re-establish the connection, but it doesn't. Resetting with the button does not help.
How can I use the board without a PC Connection ??
