Product Description

Performance:
(1) Effective transmission distance 10M
(2) The Mini51 series is a Cortex-M0 32-bit microcontroller series, which has high performance, low power consumption and fast processing speed.
Features:

Bluetooth remote control for mobile phones, safe, convenient, fast, simple, low power consumption.
Parameter:
(1) Powered by 12V power supply, output 12V;
(2) It needs its own external relay to function as a switch;
(3) Factory Bluetooth device name is SPP-CA It is best to have a unique name! Password: 1234
(4) Modify the Bluetooth device name fD 02 ef + total length 1 byte (all bytes later) + length + device name n bytes (up to 10 bytes) + length + pairing password (PIN up to 6 bytes) + 5d
(eg: modify the device name: QS-RELAY pairing code is: 1234 then send: FD 02 EF 0F 08 51 53 2D 52 45 4C 41 59 04 31 32 33 34 5D )
Modified successfully: df ff 00 00 5d modification failed, no response: df 00 00 00 5d
First, the APP sends the name of the device to be modified, disconnects the Bluetooth connection, resets the Bluetooth module after receiving the hardware, delays for a few seconds, and then configures the Bluetooth device.
4-way control code table:
1 way open: FD 02 20 01 01 5D
1 way off: FD 02 20 01 00 5D
2 way open: FD 02 20 02 01 5D
2 way off: FD 02 20 02 00 5D
3 way open: FD 02 20 03 01 5D
3 way off: FD 02 20 03 00 5D
4 way open: FD 02 20 04 01 5D
1-4 Road Open: FD 02 20 EF FF 5D
1-4 Road Off: FD 02 20 EF 00 5D
Return DF FD XX XX 5D //XXXX A total of 16 bits each bit 1 means open; 0 means off.
(5) Query the current status: FD 02 20 FF FF 5D
Returns: DF DD 00 XX 5D where XX indicates that there are several switches in total.
At the same time return: DF FD XX XX 5D //XXXX A total of 16 bits each bit 1 means open; 0 means off.
Application:
(1) Use the mobile phone Bluetooth remote control switch to expand the control range.
(2) You can use the mobile phone Bluetooth to remotely control the opening and closing of daily home appliances.
(3) Smart home appliances can be realized by using Bluetooth relays.
(4) Using mobile phone Bluetooth remotely to achieve low voltage control, high voltage, small current to control large current, improve safety factor.
(5) It is widely used in industrial electrical appliances and home appliances, and plays the role of intelligent switch.
