I,m trying to update de MKR100 Wifi FW version.
When I check the "test connection" option, I get the errot message "programmer not responding".
I'm using Arduino IDE 1.8.5.
The MKR section has some more posts about upgrading the firmware.
Hello! I think you can refer this!
"https://www.arduino.cc/en/Tutorial/FirmwareUpdater"
If you installed wifi101 library , you can upload the "firmware updater example" to your mkr1000
after it, you can use firmware101 updater gui in your C:(where you downloaded gui program) or
ide menu!
before it, you must do firmware check by firmware version check
enjoy your mkr1000!
