Other Parts Discussed in Thread: SIMPLICITI, CC2500

Hi all,

I am working on RF2500 module.the peer to peer example program is working fine for me.My doubt is that what will happen if two pairs of end devices(two talkers and two listeners) made to communicate at the same time?How is the link id is supplied to each end devices.

In my case am sending a data 0x01 from talker of 1st pair to listener of 1st pair which is already paired(also one more pair of listener and talker is paired),and in both listener program i have written the code such that if 0x01 is receiced toggle the green led.What happens to me is that the green light is toggled in both listener.Why is it so?What should I do if i want to send the data to that linked listener only??

Thanks in advance

Regards

Vignesh,

This is a very simple point to point UART example code, you will need to add some logic (extra information in your UART protocol) to be able to sort the data afterwards.

SIr,
Thanks for your response.Is there any parameter to change in the code so that If i pair a listener to a talker,the datat is received bt that particular listener only???Also what is the maximum application data size I could send in one frame?
Thanks and Regards

The CC2500 only has a 64 byte FIFO buffer, the SimpliciTI stack has a 12 byte overhead. I would suggest staying below 50 bytes at a time.
