B4R Question transmitter and receiver

[cloner7801]

Hi,

I have these and I want to write a program to send data from transmitter to receiver

@Erel Can you help me ?

One of the rules on these forums is no NOT address your questions to an individual user. This is a community forum!
This said, if I'm not mistaken, they are very basic tx/Rx modules.. using serial com should be enough for them

You need to provide more information. A good way to start is to look for an Arduino example or tutorial that is based on these specific components.

theese are receiver and transmitter that work on 433 Mhz, I tryed them with different compiler (basic like compiler for picmicro), with no success, a lot of noises and no comunication beetween, also if they were positioned to some centimeters..... better to try wifi comunications.

Here is a link to some PICBasic code that you can probably use as a guide.

The modules you listed here normally wont work as they are. They are basic AM RF modules with absolutely no digital modulation capability other than simple bang-bang comparator.

Since these are AM, you will get alot of noise. To use these radios effectively, you should couple them up to some sort of encoder/decoder to get valid data.

My advice would be use bi-phase/Manchester or some type of other encoding method to use these radios effectively.
