RE: nRF5340 Connectionless CTE not detected by Silicon Labs AoA Host (BRD4185A)

Hello Vidhi,

the first thought here is that the error code you get from the nRF5340 "Creating new ID failed (err -22)" in the log indicate that the network core of the nRF5340 isn't programmed correctly.

Q1: How are you building the code example and is the programming log showing success with writing to the network core?

Q2: Have you tried a different, non-AoA, BLE example to check that the chip and DK works as you plan? BLE uart peripheral or something like that. just to make sure the network core is programmed and running before going into thr AoA example.

Q3: boards/nrf5340dk_nrf5340_cpuapp.overlay in the AoA, how is that looking compared to a different BLE code example overlay file?

Best regards

Asbjørn
