1: Widely used

2: Control distance: 10M (open environment)

3: Provide Bluetooth relay control app

4: Stable performance

5: Easy to understand

The single channel Bluetooth relay module includes one channel 5V / 10A or one channel 12V / 10A relay module and spp-c Bluetooth serial port slave module. The switch of the relay can be controlled by sending instructions through the mobile phone app. It is a new and modified version, which is more practical and more stable.

Function description:

1. Onboard high-performance MCU and spp-c Bluetooth 2.1 slave module;

2. Provide Bluetooth relay control app;

3. Control distance: 10M (open environment);

4. Working voltage: DC12V;

5. On board 1-way 12V, 10a / 250V AC, 10a / 30V DC relay, which can be pulled in for 100000 times continuously, with diode leakage protection and short response time;

6. Onboard Bluetooth status indicator and relay indicator;

7. UART debugging interface is reserved, which can be used to modify Bluetooth pairing password, etc.

8. Board size: 62 * 20MM

1. Connect the power supply: the in + and in - of the module are respectively connected to the positive and negative poles of 5V / 12V (subject to the actual purchase) power supply.

2. Use app to control 1-way relay. There are two apps available: one is a special app for Bluetooth relay developed by LC electronics, and the other is a general app downloaded from Android application mall

2.1. Instructions for use of special app for Bluetooth relay:

2.1.1. Install the "lcbs test program" app and Bluetooth serial port transmission tool on the Android mobile terminal. Open the app and click "search Bluetooth". The default Bluetooth names are generally bta-04, jdy-30, spp-c, etc. connect the mobile phone to the Bluetooth module, enter the password and click OK (the initial password is 1234). After the connection is successful, the blue light changes from slow flashing to constant on, and then click the box to control the switch of the relay.

1 * Relay module

2 Channel:

1. Description:
The 5V dual circuit Bluetooth relay module consists of 2 5V//10A relay modules and a SPP-C Bluetooth serial slave module. The switch of the relay can be controlled by sending instructions from the mobile APP.

2. Functions:
1>. On-board loaded STM8S high performance MCU and SPP-C Bluetooth 2.1 slave module
    2>. Provide Bluetooth relay control APP
    3>. Control distance: 10M (open environment)
    4>.Operating voltage: DC5V/12V(Optional)
    5>. On-board 2 way 5V, 10A/250V AC 10A/30V DC relay, can be continuously absorbed 100 thousand times. With diode purging protection, the response time is short.
    6>. On-board Bluetooth status indicator and relay indicator
    7>. Reserve UART debug interface and STM8 SWIM program download interface
    8>. Board size: 40*64.5mm

3. Operation description:
    1>. Connection power: the IN+ and IN- of the module are connected to the positive and negative poles of the 5V power supply
    2>. Use APP to control 2 way relay
Bluetooth Relay General APP Usage Description:
    2.1>. Android mobile phone installation APP “BlueSPP-37”, Bluetooth serial port transmission tool, used to send relay control instructions. Click “switch”. Then press the gray square in the interface, and then input the name and content of the 2 relay control instructions (the instruction format is HEX) respectively.
2.2>. Open “BlueSPP-37”, APP, click "connect". The mobile phone is connected to the Bluetooth module. After the connection, the blue light turns from slow flash to steady light. Click on the gray square can send instructions to control the switch of the relay.
3>. Additional functions (as USB relay) instructions:
Prepare a USB to TT serial module, TTL module GND, TX, RX respectively relay module GND, TX, RX. On the computer, open the serial port debugging software (such as SSCOM32, select baud rate is 9600, send sixteen A0 (HEX) form A0 0101 A2 and A0 0201 A3, you can turn on the first, second way relay separately. The A0 0100 A1 and A0 0200 A2 are sent in the form of sixteen (HEX), and the first, second road relay can be closed respectively. Take the example of opening the relay as an example:
