Why is the BLE protocol stack layered? How to understand BLE “connection”? What would happen if the BLE protocol only had the ATT layer and no GATT layer? 1. Protocol Stack Framework Generally speaking, we refer to the implementation code of a protocol as a protocol stack. The BLE protocol stack is the code that … Read more
1. Introduction Through the introduction of “Bluetooth Protocol Analysis – Protocol Architecture”, everyone should have a simple understanding of the Bluetooth protocol stack, but there is certainly still a feeling of “half-understanding, half-uncertain”. It’s perfectly normal to have this feeling, as the Bluetooth protocol is a long-standing and relatively large protocol that is not easy … Read more
Overview of Bluetooth Low Energy Testing Requirements Bluetooth Low Energy (BLE) devices use a total of 40 channels, including 3 advertising channels (37, 38, 39) and 37 data packet transmission channels (1 to 36). The Link Layer data packet consists of four parts, as shown in the figure below: After the design of the Bluetooth … Read more
