Does the feather connect to the LTE link monitor app?
I have tried it to connect, but the serial port of the LTE link monitor says No devices available. Similar when trying to connect to nRF programmer.
Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device.
I guess this is due to the serial to the USB converter that is on-board is different than that recognized by the nRF Connect.
