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