I am a beginner in ESP. I am using two codes as a basis for ble. The first one is gatt_server_service_table. I noticed that this server contains 3 characteristics. The example gatt_client connects to one of these characteristics with uid16 0xFF01. My question is how to modify (as ...
Hello I'm trying to use multiple charactericts within one service. But when the Client retrieves the characteristics within BLERemoteService::retrieveCharacteristics, it fails while accessing the second characteristic: if (status == ESP_...
Everything with the UUIDs of the one service and its two characteristics sets up fine EXCEPT for the access properties: Instead of the Notify characteristic having just BLE_GATT_CHR_PROP_NOTIFY (0x10), it gets both BLE_GATT_CHR_PROP_NOTIFY and BLE_GATT_CHR_PROP_READ (0x02), which adver...
The BLE provides secure transmission of data among the devices; therefore, it is the main feature of multiple devices. It has the built-in features of encryption and authentication and can protect the data to ensure the privacy of the user. The good thing about this module is that it provid...

ESP-S3-N16R8 module has built-in ESP32-S3 series chip, ESP32-S3 series chip has the characteristics of expansion and self-adaptation. The two CPU cores can be controlled separately. The CPU clock rate can be adjusted from 80 MHz to 240 MHz. The user can turn off the power of the CP...
First ... today, we can ask a service for the BLECharacteristic object with a given UUID ... we can ask: myBLEService.getCharacteristic(uuid) If we change the design to allow multiple characteristics for the same UUID then this function won't always work. I think I can detect that and...
OK - so is what I'm trying to do - call the 'esp_ble_gattc_read_char()' function from the callback routine - the correct way to do this? Is it possible to read multiple characteristics in this way? Are there any code examples where the client reads multiple characteristics from the...

The gateway can read and write BLE characteristics from devices and provide the results in an MQTT message. TIP These actions will be taken on the next BLE connection, which occurs after scanning and after the scan count is reached,see above to set this. This can be overridden by providing...
