What ways are there to wright data blocks of bytes?
You already know 2 different ways. The difference is that, instead of using them to write 1 byte, you use them to write more.
Quote:
Maybe 10 bytes a block.
Do you actually know that? Do you know your packets are even all the same size? You shouldn't have to guess -- something, somewhere in your code must know the size of the packet you received, but you're either not keeping that result or not using it...

Unfortunately we can't see your code from here. Please post it.

Would this affect the JPEG image size, because all jpg files
have the same size, even when camera sends different size
images.
I certainly hope it would affect the jpeg image size, right now they're only going to be a tiny fraction of the size they should be.
