Mô -đun Bluetooth trên đồng hồ thông minh

The application block diagram of the smart meter is shown below. Meter MCU (management core) Interacts data with the mobile / handle app, host BLE (USB Dongle), external switch (circuit breaker), external sensor through the Mô -đun BLE on the meter. The PC side extends BLE communication capabilities through the host BLE (USB Dongle), and interacting date with the BLE module on the meter. Devices of 1 Và 2 can be a mobile phone.

Feasycom BLE module solution uses UART as the communication interface with the host (meter MCU), identifies / distinguishes the flow direction and channel number of the data through the server address and the client address of the DLT698 packet.
