Hello
I have a problem setting up communication between a nRF9161 and a nRF52840.
I have a custom board with a nRf9161 and a nRF52840. These two are connected with 5 lines.
| nRF9161 | ------ | nRF52840 |
| P0.21 | --- | P0.29 |
| P0.23 | --- | P0.28 |
| P0.24 | --- | P0.02 |
| P0.26 | --- | P0.13 |
| P0.22 | --- | nRESET |
I am using the lp_uart sample with my custom board files on the nrf52840.
Is it necessary to set the nrf52840 reset line in the custom board files? If so, please explain wy.
When i try to use the bluetooth from the nrf9161 I get this response in my logs :

I have to mention that the connection works SOMETIMES, but most of the time i get this error and the board restarts.
Could you help me with my issue please?
Thank you.
