Googled a bit but couldn't find anyone with this issue.

I use espconn_sent to send data of 21 bytes but I receive the entire 2048 bytes of the buffer on my server.

espconn_sent(conn_info, (unsigned char *)data, 21);

rcv: length = 2048 data = [IOT00001,,19.1,19.3[d][a][ffff][ffff][ffff][ffff][ffff]......

So I recieve the 21 bytes of data but I receive the rest of the 2048 buffer as well.

Am I doing something wrong, or is it a known issue?

Thanks,
lhr
