NCS1.9.1 NRF52805 not bonding

Is there any different if you use the softdevice controller vs. the zephyr controller? E.g. in prj.conf
CONFIG_BT_LL_SOFTDEVICE=y
vs.
CONFIG_BT_LL_SW_SPLIT=y

Any difference if you enable/use slave latency when you establish connection? E.g. try to set latency = 5.

    err = settings_load();
    if (err) {
        printk("Settings loaded failed (err %d)\n", err);
        shut_down();
        return;
    }

This is the code (shut_down is my custom exit functionality).

Like I said in the post, pairing_complete is never called. I think this is either a bug in the SDK or a configuration problem on my side, but I have a hard time finding it!

I can't find any errors no.

Can you check if settings_load() return any error code?

Can you also check the pairing_complete() cb whether "bool bonded" is set?
Ref static void pairing_complete(struct bt_conn *conn, bool bonded).

It took some time to get working, but here you go!

Are you able to provide an on-air sniffer log for BLE?

That was I can check if there are any errors occurding during bonding that may explain what you see.

There are no examples for passkey_entry, and the other ones just have passkey_confirm and passkey_display listed (which makes sense for the variant where the key is only displayed).

Can you take a look at some of the example project in NCS that support passkey? For instance there are both central and peripheral implementation for hids that support passkey.

that is:

static struct bt_conn_auth_cb conn_auth_callbacks = {
	.pairing_complete = pairing_complete,
	.passkey_entry = passkey_entry,
	.pairing_failed = pairing_failed,
	.cancel = cancel,
	};

I’ve tried NVS too, didn’t get far with that, but as data is being written I don’t think the storage backend is the problem.

Hello,

Which conn_auth_callbacks have you defined? Which of them occur here? Have you tried CONFIG_SETTINGS_NVS instead?

Best regards,
Kenneth
