Hi Martin

The reason you're seeing just one ID when calling nrfjprog -i is because this command displays all the debuggers connected to the PC, not all nRF devices. The DK will automatically detect when a device is connected to the Debug out header, and thus, it will program the Thingy whenever it is connected to the DK and turned on. Whenever you want to program the DK instead, you can just remove the debug cable from the DK, and the on-board chip will be programmed instead.

This can be confirmed by using the nRFConnect programmer app, where the nRF model will be printed in the log when connecting. For example, when I had the Thingy connected in and opened the programmer app the log shows Model: NRF52832_xxAA_REV1, while if I disconnect the debugger cable and connect again the log shows Model: NRF52840_xxAA_ENGB. There is no "model" command in nrfjprog though, so you won't be able to confirm this using nrfjprog alone.

Best regards,

Simon
