The Beken/RTL SDKs ship lwIP defaults tuned for a general-purpose WiFi SoC: TCP_SND_BUF=10*MSS (14.6KB), MEM_SIZE=32KB, 12 TCP + 22 UDP sockets. These waste significant RAM on memory-constrained chips. ESPAsyncWebServer allocates malloc(tcp_sndbuf()) per response chunk, and at 14.6KB this causes OOM on BK7231N. This tunes lwIP to match ESP32/ESP8266 ranges: - TCP_SND_BUF/TCP_WND: 4*MSS (was 10*MSS) - MEM_SIZE: 12KB BK72XX / 16KB RTL,LN (was 32KB) - Socket counts: dynamic from component registrations - All derived pool sizes adjusted accordingly Also splits socket consumer tracking into TCP/UDP, adds get_socket_counts() API, and updates ESP32 to use it.

Tests for ESPHome
This directory contains some tests for ESPHome.
At the moment, all the tests only work by simply executing
esphome over some YAML files that are made to test
whether the yaml gets converted to the proper C++ code.
Of course this is all just very high-level and things like unit tests would be much better. So if you have time and know how to set up a unit testing framework for python, please do give it a try.
When adding entries in test_.yaml files we usually need only
one file updated, unless conflicting code is generated for
different configurations, e.g. wifi and ethernet cannot
be tested on the same device.
Current test_.yaml file contents.
