AsyncTCP

Async TCP Library for ESP32 Arduino

This is a fully asynchronous TCP library much like the original, apart form the fact that it works properly.

If you are able, please Support me on Patreon and/or subscribe to my Youtube channel (instructional videos)

What's fixed

95% of the API is the same as ESPAsyncTCP (the ESP8266 version) apart from one minor problem: This lib does not pass through the TCP PSH flag, which means you can never receive more than N buffers' worth of data (where N is implementation-dependent) because you cannot tell which is the last packet in a multi-packet > buffer size set of data. Clue: It's the one with the PSH flag set. See the problem?

So, PSH flag collected on TCP recv, saved and made available to new API call (same as ESPAsyncTCP)

bool isRecvPush(); // is the PSH flag set, i.e. is this the last packet?

Issues

If you want a quick resolution, please follow these rules:

As with all H4 and H4Plugins libraries, please make sure you have read all the relevant documentation relating to the issue and watched any videos on the Youtube channel (instructional videos). Please also subscribe to the channel for notifications of news and updates.
If you still think there is a problem, then join the Facebook H4 Support / Discussion group and report the issue briefly there. This is because I visit the group every day, whereas I do not have time to visit 11 github repos every day. Furthermore, it alerts other users to potential problems and allows an initial assessment.
If there is a genuine issue then you will be referred to Raising H4/H4Plugins issues after which you are advised to create a full github issue report.
Failing to make an initial report in the Facebook H4 Support / Discussion group and simply starting with a github issue, or failing to include all of the information required in Raising H4/H4Plugins issues is likely to result in a long delay before it gets picked up.
