I am currently evaluating the Thingy:91X and nRF9151 DK platforms for development using the latest NCS releases (v2.7.0, v2.9.0, and v3.0.0). I have encountered two issues that I would appreciate your assistance with:
1. Debugging Issue on Thingy:91X
I am able to successfully compile and flash applications to the Thingy:91X using both thingy91x
and thingy91x_ns
targets. However, I am unable to debug the device. Regardless of the sample (e.g., pwm
or hello_dect
), when I attempt to start a debug session via west debug
, I encounter the following error:
FATAL ERROR: command exited with status 25:
nrfutil --json device x-execute-batch ...
Could you please provide guidance on how to enable reliable debugging on the Thingy:91X?
2. DECT NR+ Sample Crashes on Thingy:91X
I built the DECT NR+ sample using the nrf9151dk
target and successfully ran it on the nRF9151 DK. However, when I flash the same firmware to the Thingy:91X, it crashes at runtime with the following error:

This indicates an invalid argument passed to the modem library. From my understanding, this likely means the DECT PHY is not supported on the Thingy:91X.
Can you confirm whether DECT NR+ is supported on the Thingy:91X?
