Hello,
I'm trying to change Bluetooth name at runtime using Zephyr on the nRF700-DK. So for now I have a name defined with CONFIG_BT_DEVICE_NAME in my prj.conf that I tried to override using the following code (based on this ticket ). Unfortunately, my device always appears with the old name. Is something missing in my prj.conf file ?
static const struct bt_data sd[] =
{
BT_DATA_BYTES(BT_DATA_UUID128_ALL, MY_SERVICE_UUID),
};
static struct bt_data ad[] =
{
BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR), BT_LE_ADV_OPT_USE_NAME ),
BT_DATA(BT_DATA_NAME_COMPLETE, DEVICE_NAME, DEVICE_NAME_LEN),
};
static void bt_ready(int err)
{
if (err)
{
printk("BLE init failed with error code %d\n", err);
return;
}
//Configure connection callbacks
bt_conn_cb_register(&conn_callbacks);
//Initialize services
err = hc_bt_nus_init();
if(err){
printk("Failed to init NUS service (err:%d)\n", err);
return;
}
err = hc_ble_identity_init();
if(err){
printk("Failed to init Identity service (err:%d)\n", err);
return;
}
bt_set_name(BLE_NAME);
bt_le_adv_update_data(ad, ARRAY_SIZE(ad), sd, ARRAY_SIZE(sd));
//Start advertising
err = bt_le_adv_start(BT_LE_ADV_CONN, ad, ARRAY_SIZE(ad),
sd, ARRAY_SIZE(sd));
if (err)
{
printk("Advertising failed to start (err %d)\n", err);
return;
}
printk("Advertising successfully started\n");
k_sem_give(&ble_init_ok);
}
int hc_bt_init(){
int err = 0;
err = bt_enable(bt_ready);
if (err)
{
printk("BLE initialization failed\n");
printk("Error is %d\n", err);
}
err = k_sem_take(&ble_init_ok, K_MSEC(500));
if (!err)
{
printk("Bluetooth initialized\n");
} else
{
printk("BLE initialization did not complete in time\n");
}
return err;
}
prj.conf :
CONFIG_NEWLIB_LIBC=y #Global attroibutes CONFIG_GPIO=y #SPI attributes CONFIG_SPI=y #PWM attributes CONFIG_NRFX_PWM0=y #BLE attributes CONFIG_BT=y CONFIG_BT_NUS=y CONFIG_BT_GATT_DYNAMIC_DB=y CONFIG_BT_GATT_CLIENT=y CONFIG_BT_DEBUG_LOG=y CONFIG_BT_MAX_CONN=1 CONFIG_BT_L2CAP_TX_BUF_COUNT=5 CONFIG_BT_PERIPHERAL=y CONFIG_BT_DEVICE_NAME="My_Device" CONFIG_BT_DEVICE_APPEARANCE=962 CONFIG_HEAP_MEM_POOL_SIZE=2048 CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048 CONFIG_BT_DEVICE_NAME_DYNAMIC=y CONFIG_BT_DEVICE_NAME_MAX=30 #Tests CONFIG_NEWLIB_LIBC_FLOAT_PRINTF=y
Thank you,
Best regards
