As shown in the figure above, to implement a BLE application, you first need a chip that supports BLE radio frequency, then you need to provide a BLE protocol stack that matches this chip, and finally, you can develop your own application on top of the protocol stack. It can be seen that the BLE … Read more
Attributes play a crucial role in BLE, serving as a bridge between different components. Today, let’s learn about the concept of attributes. Attributes: The architecture of BLE is divided into servers and clients. The way BLE works is by storing data on the server, which the client can access. Data is stored in a format … Read more
