According to this document
https://www.eremex.ru/upload/iblock/d11/lwip_rawapi.pdf
the top of page 4 says:
"TCP data is sent by enqueueing the data with a call to tcp_write(). When
the data is successfully transmitted to the remote host, the application
will be notified with a call to a specified callback function."
So I think you should do the same instead of successive tcp_writes without
being sure that the data was sent.
