Hi
I use RF modules from HOPERF Electronic, they are not expensive, the receiver module uses an RFM83C integrated circuit. Thanks for the article you suggested.

Hello
Okay, that's no problem. I use the UART component.

Hi
I don't have HC-05 modules, nor USB-TTL serial converter, I only have RF 433MHz modules that work, for tx a pin in data and for rx a pin out data.

Sorry, I forgot the flowchart.

Hello
They are 433MHz RF modules, they are simple, they work because I test on the same development boards with 16F877A other string sending and receiving programs.

Hello everybody
I did not get the expected results, the LED does not light up. I did a test by connecting the development boards with wires and it works like that, but in RF it doesn't work. If the data is received in RF, shouldn't the received string be found in the "receiver" variable?

Hi
Thank you very much medelec35 for the link, it really adds to what interests me.

Hi
Thank you very much for the answer, I think it will help me.

Hello! I have a question. I want to transmit the string "AD1CB4E1AA2EDDAF" through the serial communication pin (RC6) of the PIC16F877A using a transmitter RF module and receive the string using a receiver RF module connected to the pin (RC7) of the second PIC16F877A, and as confirmation that the st...

Thank you very much for the details.

If it is as you say, it is good. I will try to install and run the program without internet, but I know it didn't work. I installed it on the desktop without problems, but it is permanently connected to the Internet. Thank you all for the technical support. If I buy the 8-bit PIC package, will it wo...
