Product description

If you have any questions, please feel free to contact us and we will answer your questions as soon as possible.

:

(1) Effective transmission distance 10M

(2) The Mini51 series is a Cortex-M0 32-bit microcontroller series, which has high , 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 I 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.
