CC2564: Data Transfer Issue

Manoj Chandran

Intellectual 260 points

Part Number: CC2564

Hi,

We are using Ti’s Bluetopia Stack and developed application based on SPP demo in our design. We are facing a problem while sending /receiving data. From the client side after establishing connection with the server, if we send 45 to 75 bytes of data packet, we are unable to receive it in the server side. For any other number of byte it is working fine. But at the same time, if we send 10 byte packet immediately after establishing connection and then sends 45 to 70 bytes of data, it works fine. Could please comment on the this?

Regards

Manoj

Are both client and server using Blutopia with CC2564?

Yes. Same setup with one board as server and another as client.

What platform are you using with the CC256x board? In addition, what are your config parameters (Buffer size, frame size)?
