Hi,
I am trying to receive messages via Bluetooth mesh and forward them via UART (using UART async API) on the nrf9160DK. But when I try this, I get an assertion error from the HCI core indicating a timeout (see logs). Below you can see my configs and source code.
Does anyone see if I have made a mistake somewhere?
Thank you in advance and happy new year tomorrow!
