Pin function and application

JDY-33 general application only needs to connect 4 pins of VCC, GND, RXD, TXD, such as in the connection state.

Disconnect, send AT+DISC\r\n, and send deep sleep to AT+SLEEP\r\n when not connected.

After deep sleep, you can wake up by the falling edge of the EN pin, or you can wake up the data through the serial port.

Use the serial port to send AT+VERSION\r\n command to wake up

About Working mode:

Momentary:Push the remote button , the relay connects, release the remote button , the relay dis-connects. Toggle:Push once the remote button , the relay connects , push twice the remote button , the relay dis-connects . Latching:Push the remote button A, the relay connects, push the remote button B, the relay dis-connect. Tiem delay mode :Push the remote control button , the relay connects , from when release the remote button , after 5s or 10s or 15s , the relay disconnect automatically. Clearing the code : Method 1： Push the learning button on the receivers for 8 times , the codes will be cleaned; Method 2： Keeping press the Learning Button on the receiver until the LED indicator ON and then flash,until it flash for 8 times. it mean the code have been cleared successfully; After clearing the code, all the remote control cannot work any more.

Learning the code :(Momentary) Push the learning key on the receiver 1 time , it comes into momentary setting mode . Wait for a moment , the LED will be off , it comes into learning state . Push the remote button , LED indicator on the receiver board will flash then come off . After 3 seconds, the LED indicator will be on again , learning successfully .

Learning the code : ( Toggle ) Push the learning key on the receiver 2 times , it comes into toggle setting mode Wait for a moment , the LED will be off , it comes into learning state . Push the remote button,LED indicator on the receiver board will flash then come off. After 3 seconds , the LED indicator will be on again , learning successfully .

Learning the code 🙁 Latching ) Note: When you choose for latching mode , in order to learn more remote control , you need to learn two different button , the first time learnt is for “ON”, the second time learnt for “OFF”. For example : button A = ON , button B = OFF Push the learning key on the receiver 3 times , it comes into latching mode . Wait for a moment , the LED indicator on the receiver board will flash then come off. Push the remote button A . LED flash for 5 times . Push the remote button B . Led flash for 5 times . After 3 seconds , the LED indicator will be on again , learning successfully. A = ON , B = OFF .

Learning the code 🙁 Time delay mode ) Push the learning key on the receiver 4 times , the time dealy for 5 seconds . Push the learning key on the receiver 5 times , the time delay for 10 seconds . Push the learning key on the receiver 6 times , the time delay for 15 seconds . The LED indicator will be off . Push the remote button , LED flashes and off . After 3 seconds , the LED indicator will be on again , learning successfully .

HC-06 Bluetooth RF Transceiver…

ktechnic — Tue, 04 Aug 2020 21:06:24 +0000

Description

This is a bluetooth module for use with any microcontroller. It uses the UART protocol to make it easy to send and receive data wirelessly. The HC-06 module is a slave only device. This means that it can connect to most phones and computers with bluetooth but it cannot connect to other slave only devices such as keyboards and other HC-06 modules. To connect with other slave devices a master module would be necessary such as the HC-05 version which can do both master and slave.
