hardware setup:
connected two xbee modules to two raspberrypi, configured one xbee as coordinator(receiver) and the other as router(sender).
we are able to send text file over xbee transparent mode.
problem:
we are unable to send complete image file over this setup. below is the code used for sending and receiving image.
on the receiving side we are able to see the garbage (may be image received),but unable to view it in any image viewer.here we are facing error:fatal error reading jpg image file.
error:interpreting jpeg image file (not a jpeg file:starts with 0x00 0xd6)
can someone help us in doing this as soon as possible.
thanks in advance.
