Overall, YES.

However, i tried it and it's isn't that simple.
I used the Programmer to Erase & write (since im using jlink).
but i get no prints and WireShark dosnt show me any sniffer options.

Nice!

The code for the dongle is not pin specific, as it uses USB to communicate.
Try to connect the debugger to the thingy:91, and and select the switch to "program nrf52". Then program the dongle code for the sniffer to the Thingy and see if that works.

With the debugger, you should be able to reprogram the original Thingy nRF52 firmware later when you want to use it for something else.

Does this make sense?

To use the Thingy91 as a sniffer, you need to re-program the nRF52840 on the Thingy91.
For this, you need a debugger or DK. Do you have that?

Exactly!

I currently have a thingy91 for a different use and i want it to be able to be a sniffer.

Hi,

For context, why do you want to use the Thingy91 for a sniffer, and not something else, like a nRF52840Dongle?
