bt_le_adv_start returns -11

[frankbuss]

I'm calling this function from a Zepyhr project:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/connectivity/bluetooth/api/gap.html#group__bt__gap_1gad2e3caef88d52d720e8e4d21df767b02

It returns -11, when I set CONFIG_BT_SETTINGS=y. With CONFIG_BT_SETTINGS=n it works. The settings system itself works: I enabled the settings shell, and can write and read values, and list all keys.

What does error -11 mean for this function, and where is it documented?

Hello,

Have you tried to load the settings data before you started the advertising like how it is done in the peripheral_lbs sample here: https://github.com/nrfconnect/sdk-nrf/blob/main/samples/bluetooth/peripheral_lbs/src/main.c#L226 ?

Error -11 (EAGAIN) indicates that the BT_DEV_READY flag has not been set, and this flag will be set after the settings handler has been loaded.

Best regards,

Vidar
