HC-05 HC-06 Bluetooth to Serial Adapter module Group CSR Master-Slave 51 MCU new original
AT instruction set
HC-05 embedded Bluetooth serial communication module (hereinafter referred to as module) has two working modes: command response work
Mode and automatic connection mode, in the automatic connection mode module can be divided into Master (Master), Slave (Slave)
And Loopback (Loopback) three job roles. When the module is in automatic connection mode, it will automatically be set according to the prior setting
The mode of connection for data transmission; When the module is in command response mode, all the following AT commands can be executed
Send various AT instructions to the module, set control parameters for the module or issue control commands. External pins through the control module
(PIO11) input level, which can realize dynamic conversion of module working state.
