Helo Every 1.

I bought TWR 2.4G for communication between two cards,to sent and reciever data…i have some questions because i am also new and i have no idea how to use it properly…kindly help me

1.What is the distance limit of this module ?And can we limit its range ?
2.After making its circuit.What is the first step to configure it ?and vice versa if someone has properly configured and test it in running condition…i will really thankfull for his help.

Hope MAny nice peoples will help me.

Thanks[/b]

o ya … i have got the same module…

so its range is 80 to 100ft…

now can you answer my questions…please:)

you can’t expect a reply when you do not include any information!

  1. HOW are you communicating with the modules? PC to PC? Microcontroller to Microcontroller? Which microcontroller? ASM or C?

  2. A schematic and the software you are using would be the first step in someone attempting to solve your problem. Without that I highly doubt anyone will answer your post.

Good Luck

hmm ok

ya you are right

welll there are two boards

say 1 is working as reciever and other is card

Card has got ID ,Reciever is attached with PC through serial port.

When the user with card will enter the arena.,reciever wil recieve the id from card and send it to PC and update the database.

Modules are connected with Atmel 80C51 on port 0.

Now after the circuit.whats the next step to make thse modules running??

i did a project here:

http://www.avrfreaks.net/index.php?modu … em_id=1121

I used avr because the 8051 devices I have here do not work with 3.3V (they are 5V devices)

If you understand assembly code you will find it very easy to follow.

Good Luck

Ahh

i just want to know the steps…will it be configure through programming ???or i have to use some other tools too??

any idea buddy?

yes it is configured through programming on startup.

you can read about this in the datasheet of the RF24G.

Good Luck

89C51 does not work with 3 Volts. It can be used with a level converter but if you are new at this, I strongly advise you to get a microcontroller that runs with 3V.

Yes it does, look here:
