Features
- Supports retained messages (not activated by default)
- Async Wifi compatible (me-no-dev/ESPAsyncTCP@^1.2.2)
- Very fast broker I saw it re-sent 1000 topics per second for two clients that had subscribed (payload ~15 bytes ESP8266). No topic lost. The max I've seen was 2k msg/s (1 client 1 subscription)
- Act as as a mqtt broker and/or a mqtt client
- Mqtt 3.1.1 / Qos 0 supported
- Wildcards supported (+ # $ and * (even if not part of the spec...))
- Standalone (can work without WiFi) (degraded/local mode)
- Brokers can connect to another broker and becomes then a proxy for clients that are connected to it.
- zeroconf, this is a strange but very powerful mode where all brokers tries to connect together on the same local network.
- small memory footprint (very efficient topic storage)
- long messages are supported (>127 bytes)
- TinyMQTT is largely unit tested, so once a bug is fixed, it is fixed forever
