I have two WIO Terminal devices that behave the same way. Both have been used only to run demo files from the Arduino IDE.
I want to install uf2 files for the LoRaWAN Gateway Tester project.
I can put the device into bootloader mode by double clicking the slider button, the blue LED fades on and off, and the “Arduino” folder appears in File Manager (Win10) as expected.
The folder contains the three files as expected - CURRENT.UF2, INDEX.HTM, INFO_UF2.TXT
The contents of INFO_UF2.TXT are:
UF2 Bootloader v3.7.0-79-gd73dd64 SFHWRO Model: Wio Terminal Board-ID: SAMD51P19A-WioTerminal-v0
When I drag a uf2 file into the folder, I am expecting the device to reboot, but nothing happens.
I have also tested with other uf2 files with the same result.
What am I doing wrong?
Do I need to install a new bootloader?
Any help appreciated.
