Set Device Name
I am using Nordic Semi nRF52840 to advertise in Coded PHY then other devices are scanning for the Device name set within the advertising packet as shown below.
What would help me a huge amount is if you would be kind enough to show me how to configure a device name within a Coded PHY advertising packet created by NimBLE-Arduino
Sorry to be a nuisance for asking :)
#define DEVICE_NAME CONFIG_BT_DEVICE_NAME #define DEVICE_NAME_LEN (sizeof(DEVICE_NAME) - 1) static struct bt_le_ext_ad * ext_adv;
static struct bt_le_adv_param *adv_param_codedphy = BT_LE_ADV_PARAM(BT_LE_ADV_OPT_USE_IDENTITY | BT_LE_ADV_OPT_USE_TX_POWER | BT_LE_ADV_OPT_CODED | BT_LE_ADV_OPT_EXT_ADV, BT_GAP_ADV_FAST_INT_MIN_1, BT_GAP_ADV_FAST_INT_MAX_1,NULL);
#define Ozark_Advert_Data_Length 70 #define MANUFACTURER_ID 0x0059
static uint8_t Advert_Ozark[Ozark_Advert_Data_Length];
static struct bt_data ad[] = { BT_DATA(BT_DATA_NAME_COMPLETE, DEVICE_NAME, DEVICE_NAME_LEN), BT_DATA(BT_DATA_MANUFACTURER_DATA, Advert_Ozark, Ozark_Advert_Data_Length), };
I'm not sure about the code you've provided above, but in this library the call structure would be:
NimBLEExtAdvertisement extAdv(primaryPhy, secondaryPhy);
extAdv.setName(DEVICE_NAME);
NimBLEExtAdvertising* pAdvertising = NimBLEDevice::getAdvertising();
pAdvertising->setInstanceData(0, extAdv);
pAdvertising->start(0, advTime);
Thank you so much, extremely helpful. My understanding is that the following call forces a reboot, is there a more delicate way of doing the following:
Stop advertising Delete advertisment Create advertisment Start advertising
esp_sleep_enable_timer_wakeup(sleepSeconds * 1000000);
There is no way to avoid the reboot if you need to use deep sleep. If you want to use light sleep I think you can just deinit the BLE/WiFi stack and enter light sleep then re-init etc. on wake-up. I can't say for sure though if that will work as I have not tried it.
One more thing.
Are we able to dynamically change the advertising packet? Ignoring any sleep functionality.
Yes, as long as you stop advertising first. After that you can change whatever you like in the same way you originally set it.
As mentioned on Gitter, I have set the name correctly I believe, however I'm unable to see any transmissions, any help would be very much appreciated.
