bluetooth module on smart meter
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 BLE module 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 and 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.
bluetooth smart meter solution
Feasycom has a series of solutions in the smart meter industry, not only including the Bluetooth demand of 2 master-3 slave connection by the National Grid, but also the Bluetooth-Wi-Fi combo solution. The following three solutions are recommended by Feasycom in the smart meter industry:
FSC-BT630 BLE module, using Nordic 52832 chip, support the connection of 2 master-3 slave, ultra-small size: 10 x 11.9 x 1.7mm, Bluetooth 5.0, and FCC, CE, IC, certificated.
FSC-BT681 BLE module, using AB1611 chip, support Bluetooth 5.0, 2 master-3 slave connection, it is a cost-effective solution which could meet national Grid requirements.
The FSC-BW236 is aBluetooth-Wi-Fi combo module. Bluetooth part supports BLE 5.0 profiles, Wi-Fi part supports dual-band 2.4G and 5G, which can be used on the smart meter and collector.
