Sodaq one V2 can't upload program

Hi Everybody,

I’m using Sodaq one version 2,which was working fine until yesterday i can’t upload mycode anymore , all i get is this :confused:

> Using library Wire at version 1.0 in folder: C:\Users\Egm001\AppData\Local\Arduino15\packages\SODAQ\hardware\samd\1.6.11\libraries\Wire 
> Using library Sodaq_wdt at version 1.0.1 in folder: C:\Users\Egm001\Documents\Arduino\libraries\Sodaq_wdt 
> Sketch uses 12404 bytes (4%) of program storage space. Maximum is 262144 bytes.
> Forcing reset using 1200bps open/close on port COM32

i’m using:

  • Windows 10, 64 bits
  • Arduino 1.8.4

So, Does Anybody has an idea on how to fix this problem ?


Try double tapping the reset button. If you have the Base board, press the reset button twice about 1 second apart. If not, then you will need to briefly connect the reset pin to GND, again twice about 1 second apart.

If there is some code which you loaded which is causing issues, this can help as it will put the board into bootloader mode.

Note: When in bootloader mode, it will show up on a different COM port number. Also, only reset twice, if you press reset a third time, it will restart in normal mode.

after pressing the reset button twice should i disconnect the reset pin from the GND immediatly or let it connected ?

Temporarily grounding the reset pin will cause the board to reset.
You should ground the reset pin (less than 1 second is more than enough) and then disconnect it from the ground.
You should do this twice to double tap the reset.

In the end the reset pin should not be still connected to ground.

Thank you, it’s uploading again
