How do I know if my HC12 is working?

The HC12 Tester was designed to allow students to verify that their HC12 board functions properly. The tester works by outputting a high signal to one port and reading that port with three or two other ports. For example, to test port A, a high signal is outputted to each of the pins of port A.

How do I connect to HC12?

Begin by connecting the HC-12 transceivers to each Arduino:

1. Connect the HC-12 “Set” pin to Arduino pin 6.
2. Connect the HC-12 “RXD” pin to Arduino pin 4.
3. Connect the HC-12 “TXD” pin to Arduino pin 5.
4. Per the datasheet, connect a 22 µF to 1 mF reservoir capacitor in parallel with the HC-12 “Gnd” and “Vcc” pins.

What is HC12 module?

HC-12 wireless serial port communication module is a new-generation multichannel embedded wireless data transmission module. Its wireless working frequency band is 433.4-473.0MHz, multiple channels can be set, with the stepping of 400 KHz, and there are totally 100 channels.

What is CC1101?

CC1101 is a low-cost sub-1 GHz transceiver designed for very low-power wireless applications. The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 600 kbps.

How to send data over the HC12 RF module using Arduino?

We will use 2 Arduinos with a HC-12 module connected to each of them as you can see in the image. For both Arduinos we connect pin 2 to TX and pin 3 to RX. Ground to ground and VCC to 5v. At one Arduino we will add a push button as you can see in the image. To work with 2 Arduinos on 1 computer, we have to open 2 instances of the Arduino IDE.

How to connect two Arduinos to one computer?

For both Arduinos we connect pin 2 to TX and pin 3 to RX. Ground to ground and VCC to 5v. At one Arduino we will add a push button as you can see in the image. To work with 2 Arduinos on 1 computer, we have to open 2 instances of the Arduino IDE.

What do you need to know about the hc-12 transceiver?

The HC-12 is a 100mW multi-channel wireless transceiver you can use in your projects to transmit and receive serial information. Learn about the HC-12 transceiver module and how to use it to transmit and receive digital data.

Where can I find the hc-12 user manual?

A full manual can be found in the ZIP archive under the name HC-12 User Manual.pdf Connect the HC-12 as shown in the image and connect the Arduino to your computer. Copy and paste the contents of the file named “HC-12 AT Commander.txt” from the ZIP archive and upload to your Arduino. Open the serial monitor and type “AT”.
