Hi,
I have successfully created a BT Peripheral which uses a static/fixed passkey upon connection with my phone (nrf connect mobile) or using the nrf52840 dongle. When I connect with the peripheral, I am prompted for the passkey on my phone or desktop and succedes to connect after writing the same "123456" passkey every time.
What I am struggling with, however, is how to connect to the peripheral with a Zephyr/NCS Central using the fixed passkey. Could you please aid me in getting this to work?
My Peripherals auth connection callback struct looks like:
static struct bt_conn_auth_cb auth_cb = {
.cancel = auth_cancel,
.passkey_display = auth_passkey_display,
.pairing_confirm = NULL,
.pairing_complete = pairing_complete,
.pairing_failed = pairing_failed,
};
and my Centrals auth connection callback struct looks like:
static struct bt_conn_auth_cb conn_auth_callbacks = {
.cancel = auth_cancel,
.pairing_confirm = NULL,
.passkey_confirm = passkey_confirm,
.pairing_complete = pairing_complete,
.pairing_failed = pairing_failed};
I though perhaps the Central would accept the Peripherals fixed passkey through:
static void passkey_confirm(struct bt_conn *conn, unsigned int passkey) {
char addr[BT_ADDR_LE_STR_LEN];
bt_addr_le_to_str(bt_conn_get_dst(conn), addr, sizeof(addr));
int err;
unsigned int fixed_passkey = 123456;
if (passkey == fixed_passkey)
{
err = bt_conn_auth_passkey_confirm(conn);
if (err)
{
printk("failed to confirm passkey, err: %d\n", err);
}
}
}
But that doesn't work. Any suggestions?
Thanks a lot in advance!
Best regards,
Jonas
