Sara R412M sketch upload fails

I have two Sodaq Sara R412M boards. Everything worked fine for some time. Now when I try to upload a new sketch, I’ll get a message “An error occurred while uploading the sketch”.
Arduino IDE finds a board and I can read board info but upload fails. Both boards work the same way. Could you help me what to do to solve the problem?

Hi @hasmala,

You can put the boards manually in bootloader mode.
Connect your device to your pc and double press the reset button.

Let us know if this solved your problem!

Best regards,


Hi Jan!

Thank you it helped. After one upload it works like before.
