Wio LTE USB COM port issue: Input/output error

Hmm than it looks more like a software problem on the WIO module itself. Just setup the arduino IDE on my other computer. But unluckily without success. Same error.

  • I installed Arduino 1.8.12

  • Added this https://raw.githubusercontent.com/Seeed-Studio/Seeed_Platform/master/package_seeeduino_boards_index.json to the Additional boards manager URLs in my preferences.

  • Downloaded the Wio_LTE_Arduino_Library (master as zip)

  • Added the library as ZIP to Arduino.

  • In the board Manager I installed Seeed STM32F4 Boards version 1.2.5

  • Loaded the example SMSRead

  • Selected the WIO Tracker LTE board under Tools

  • Build (no errors)

  • Upload

But same behaviour as before…

Did I miss something?
