Simple switch using RF-24G transceiver

Wireless & IoT
1

I’ve been trying to design an on/off wireless switch using the RF-24G transceiver with out any luck.

  1. Is it possible to send/receive a simple on signal and off signal with out using a microcontroler?

  2. If so how

I’ve been racking my brain for weeks.

Please help

Thank you

Hotek encoder and decoder chips are commonly used with RF and IR.

4 bit or 8 bit codes…

cheap ones are at the bottom of the pages

Thank you stevech!

I’ve bought the HT-12D and HT-12E decoder/encoder as suggested below, and have realized how naive I am.

I have no development board to use with the RF-24G and am unable to configure the transceiver to send data or receive data for that matter.

Is there a way to send data with out any configuration of the nRF2401?

The end goal is to simply turn on and off a device.

I am desperate, any advice is greatly appreciated.

The RF-24G requires you to clock in some bytes of data, then set a high on the transmit pin and it will spit out the signal to the reciever.

Then on the receiving side, you will need to clock the data back out.

All of this requires a microcontroller. So the 24-G is really overkill for just a single on/off switch.

You might be able to do something much simpler and cheaper but I’m unaware of the specifics of your project.

Thank you bushman

Yes I am looking for a simpler transceiver. The reason it needs to be 2.4ghz is it will be simpler for FCC approval. I am having trouble finding products that will send a simple address, with no need to transmit much data.

Again any advice is greatly appreciated.

In that case I just can’t imagine what you would find that that wouldn’t require some kind of micro controller on both ends to do the work for you.

Can you describe the project?

Would the TLP-434 work? It sounds like what you might need. It is under the General category on wireless on SparkFun’s main website, and it comes in 4 different types

I built a 8 channel remote control, out of a TRW24 and 18F1320 PIC :slight_smile:

Did you ever get this to work, cause im trying to achive the same goal. I just need to transmit an on signal to a reciever to light up an led, thats it. If so could you send me the schematic and any code you used if any. Thanks its greatly appreciated!!!

I’ve got a PCB design and software for a very simple Tx and Rx pair using SFE nRF24L01 modules and PIC18F4520 chips. The boards have a pushbutton and LED.

Are those encoder/decoders actually RF transmitter/receivers on their own then without any other chips? If so thats quite cool.
