Good to hear that did the trick. I will close the case then 🙂

As I short the SD22, it works fine. Thanks a lot!

By default P0.20 is connected to the flash memory chip on the DK, and is not available on the pin headers.

In order to make P0.20 available on the pin header you need to cut solder bridge SD12 and short solder bridge SD22, as described here.

As a hot tip, if you look on the backside of the DK you can see all the default GPIO assignments, and which solder bridges you need to cut/short in order to make a pin available.

Best regards

P.S. I set the 'BSP_BTN_BLE_ENABLED' value to 0 to prevent P0.20 is used for BSP function.

Also, I'm using nRF5 SDK 16.0.0.
