The library was using
socket.send()directly, but not checking the return value to see if all the bytes were sent. So for larger packets, a partial send would go unnoticed. Added_send_bytes(), which callssend()until all bytes are sent, and also handlesEAGAIN. I could have usedsocket.sendall(), but it doesn't handle EAGAIN.I tested by sending 2900-byte packets to a no-history Adafruit IO test feed. @manchicken, who submitted #230, also tested.
