Hi,

It seems that the PC isn't able to establish a J-link connection. Could see if the device is listed if you use nrfjprog and issue the command:

nrfjprog --ids

If it isn't, please go through the steps listed in this thread and see if the solves the issue.

Lastly, PlatformIO isn't an extension that we are able to offer support to, we generally recommend using one of the IDE's that are used in the SDK.

regards

Jared

I know you don’t do support for platform io. . here are the ids 683070858

I think I accidentally added one to many download txt, and one without the board attached.

Is this better.

Ok I will go back to the adafruit board and give up on this.

Thanks anyway.

Ps. Is it correct when code is downloaded the mcu led dim's very short Avery sec.
