In bridge mode, user 's MCU can communicate with the mobile device in two-way through module's UART. Users can also manage and control certain communication parameters through specific UART AT commands.The detailed meaning of the user data is defined by the up-application. Mobile devices can write to the module through the APP. And the data written will be sent to the user’s MCU through UART.Then the module will transmit the data package from user MCU to the mobile devices automatically.In the development under this mode, the user need to undertake the code design for MCU code,and the code design of APP for smart mobile terminals.
In Direct-Drive mode, users take simple periphery expansion to the module. And APP drives the module directly through BLE protocol, to implement the monitoring and control of the module by smart mobile devices. In this mode, users only need to do the code design for smart mobile terminals.
