How Does A Bluetooth Module Work ?

- Jun 24, 2019-


Thanks for browsing this article ,we are going to talk about ''how does a bluetooth module work with the MCU '',and how it can read/write parameters ,and how it can establish connection and communication .we plan to use FSC-BT826E as an example .


Communicate with MCU

                                              MCU1

This is the minimum system for a quick test. For the qualified circuit reference design, please refer to  FSC-BT826E’s datasheet.

Read/Write Parameters

l  Read or write the module’s parameters by AT commands is allowed in AT-command state, please refer to Section 2.2 for the timing that the module enters AT-command state.

l  Device name, PIN code, baud rate, MAC address are the most frequently used parameters in applications. For more information about AT commands programming, please refer to FSC-BT8XX Programming User Guide V3.2(Dual-Mode Data Transiver). For programming example, please refer to Feasycom Module Programming Example 1.1.

l  Typical Read/Write Parameters Interaction:

Data Throughput

l  Full duplex transparent communication is available in throughput state, please refer to Section 2.2 for the timing that the module enters throughput state.

l  For programming example, please refer to Feasycom Module Programming Example 1.1.

l  Typical SPP Slave Data Throughput Interaction:
