<p><b>New page</b></p><div>== '''Product name''' ==<br />
12V dual-channel bluetooth relay IoT smart home mobile APP remote control switch<br><br />
<br />
<br />
<br />
== '''About LC-BT-2-2''' ==<br />
LC 12V dual-channel Bluetooth relay module includes 2-channel 12V/10A relay module and SPP-C Bluetooth serial port slave module,Commands can be sent through the mobile APP to control the switch of the relay<br><br />
<br />

== '''Introduction instruction''' ==<br />
Board size：64.5*40mm<br><br />
[[File:BT-2-2-4.png]]<br><br />
1.IN+, IN-: 12V power input<br><br />
2.TX, RX: UART serial port pins<br><br />
3.5V, GND, SWIM, NRST: MCU program download port<br><br />
4.LED D2/D4 (red light): relay working indicator light, lights up when turned on<br><br />
5.LED D1 (blue light): Bluetooth status indicator light, described as follows<br><br />
(1) When it flashes slowly, it means waiting to establish a connection with the mobile phone.<br><br />
(2) When it stays on, it means the connection is successfully established with the mobile phone.<br><br />
6. The two reserved jumper caps: please insert them to the right end during normal use (i.e. RX is connected to RX1, TX is connected to TX1),If you want to use the USB to TTL serial port module alone to debug the SPP-C module, please insert both to the left (otherwise there may be interference)<br><br />
7.<br><br />
COM1：Public terminal<br><br />
NC1: Normally closed terminal, short-circuited with COM1 before the relay is closed, and left floating after closing<br><br />
NO1: Normally open, the relay is left floating before closing, and short-circuited with COM1 after closing<br><br />
COM2：Public terminal<br><br />
NC2: Normally closed terminal, short-circuited with COM2 before the relay is closed, and left floating after closing<br><br />
NO2: Normally open, the relay is left floating before closing, and short-circuited with COM2 after closing<br><br />
8. Relay control instructions (hexadecimal hex format)<br><br />
Open the first relay: A0 01 01 A2<br><br />
Close the first relay: A0 01 00 A1<br><br />
Open the first relay: A0 02 01 A3<br><br />
Close the first relay: A0 02 00 A2<br><br />
<br />
<br />
<br />
== '''Function features''' ==<br />
*Onboard 8-bit high-performance microcontroller chip and SPP-C Bluetooth 2.1 slave module<br><br />
<br />
*Provide Bluetooth relay control APP<br><br />
<br />
*Control distance: 10M (open environment)<br><br />
<br />
*Working voltage: DC12V<br><br />
<br />
*Onboard dual-channel 12V, 10A/250V AC 10A/30V DC relay, which can be connected continuously for 100,000 times, has diode overflow protection and short response time<br><br />
<br />
*Onboard Bluetooth status indicator and relay indicator<br><br />
<br />
*Reserved UART debugging interface and MCU program download port<br><br />

== '''Use description''' ==<br />
'''1.Tool software'''<br><br />
①"LCBS Test Program" APP, used to send relay control instructions<br><br />
[[File:BT-1-2-4.png]]<br><br />
<br />
②"BlueSPP_37" APP, used to send relay control instructions<br><br />
[[File:BT-1-2-5.png]]<br><br />
<br />
③USB to TTL module and Dupont cable, used to implement additional functions and modify Bluetooth name and password<br><br />
[[File:BT-1-2-6.png]]<br><br />
<br />
④Dupont wire, used to connect modules<br><br />
[[File:BT-1-2-7.jpg]]<br><br />
<br />
<br />
'''2.Use description'''<br><br />
'''(1) Bluetooth relay dedicated APP "LCBS test program"'''<br><br />
Install the "LCBS Test Program" APP on the Android phone, a Bluetooth serial port transmission tool, open the APP, click "Search Bluetooth", connect the phone to the Bluetooth module, enter the password and click Confirm<br><br />
After the connection is successful, the blue light will change from slow flashing to steady light, and then click the square to control the relay switch<br><br />
