I am pretty new to this, so I reckon something went wrong.
I was testing the new board we got, which is SODAQ SARA R410M using Arduino IDE.
The documentation states that the board has LSM303AGR accelerometer, so after trying out the examples using LED's, I wanted to further explore the board by trying this example. (Note, that the example is from the SARA AFF N211, but loaded on the R410M.) However, after doing so I am not able to reset or access the board. After attaching it to my Mac using USB cable (MacOS 10.14) it shows up for a second in the ports list, but then immediately disappears. I am hence not able to load any other software on the board or to access it all together. The built-in blue LED is also silent
Any advice on how to reset the board would be appreciated.
