I tried that, but it caused problems with using the COM port with Serial.print. So I used : https://raw.githubusercontent.com/Seeed-Studio/Seeed_Platform/master/package_legacy_seeeduino_boards_index.json
Which allows you to load code onto the board and also monitor the COM port for Serial.print. However, since Twilio no longer supports SMS text, and the Wio LTE does not support secure connections, there isn’t much point in continuing to use the board.
