Fresh Build and Flash of Bluetooth Peripheral Sample Produces Error on P-Nucleo-64 Board (STM32WBRG)

[smr-mohammadzadeh]

Hi there. I am new to Zephyr OS and for the first try, I tried to build and flash bluetooth peripheral sample to P-Nucleo-64 board which is powered by STM32WBRG micro controller. The sample flashed successfully but I have got this error in serial terminal:

*** Booting Zephyr OS build zephyr-v3.0.0-2567-g70c48417c7a0  ***
Bluetooth init failed (err -5)
[    0.152000] <0x1b>[0m<inf> fs_nvs: 2 Sectors of 4096 bytes<0x1b>[0m

[    0.155000] <0x1b>[1;33m<wrn> bt_hci_core: opcode 0x1003 status 0x01<0x1b>[0m

I couldn't found any information about bluetooth initiation error codes, so I couldn't figure out what does error "-5" mean.

What I have done from scratch:

[ 0.155000] <0x1b>[1;33m<wrn> bt_hci_core: opcode 0x1003 status 0x01<0x1b>[0m

This looks like the Controller did not support the Read Local Supported Features command (OGF 0x04, OCF 0x03), since it returned a status of 0x01. The usual completion report would look like:

[00:00:00.386,779] <dbg> bt_hci_core: hci_cmd_done: opcode 0x1003 status 0x00 buf 0x20007c28

So this is a problem with the controller (i.e. the Link Layer), I suggest you contact @erwango.

Closing as not a Zephyr issue, please reopen if this is not the case.
