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 ...
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...
