Arduino UNU R4 WiFi board.

Hallo.

By loading a program:

No device found on COM6

Failed uploading. uploading error: exit status 1

How can I fix this problem?

Jack.

There are a number of posts about missing com-port/ failing to upload on the Arduino Forum (e.g. https://forum.arduino.cc/t/device-not-s … 1142476/83)

Check whether that helps.

Examples downloaded need to be updated to include Wire1 and not Wire

Wire1.begin(); //Join I2C bus

also

if (button.begin(SFE_QWIIC_BUTTON_DEFAULT_ADDRESS, Wire1) == false)
