Hi,
utkarshraj:
I was trying to create a TCP Server which fetches information being sent over a port. The server works fine as long as I am transferring strings of code using the wifi shield.
So you have a reliable transport for data from your Uno to your PC, it's only you've not managed to reconstruct the image from your HEX representation successfully? Sounds to me like you're close to getting this solved. If you can verify the data received is the same as what you're sending then surely your final hurdle is rebuilding the image file at the PC end?
BTW on these forums, be sure to enclose any code in [code ] tags so it's more readable.
Cheers ! Geoff
