<div class="markdown_content"><p>It looks it is 16 bytes. But Syscomwrite can write more then 16. And Syscomrecieve can do more then 16. So why recieves it 16 byte at a time and not everythink ones</p></div>

<div class="markdown_content"><p>I use Syscom Library, But it recieves everytime max 16 bytes. Why not more at once ? If is send 23 byte. I recieve 16 and 7 bytes .. </p></div>
