 ## Features

- Very (very !!) fast broker I saw it re-sent 1000 topics per second for two
+- 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
+
+## Limitations
+
+- Max of 255 different topics can be stored (change index_t type to allow more)
+- No Qos because messages are not queued but immediately sent to clients

  that allows to add clients publish, connect etc with interpreted commands.

+## Retained messages
+
+Qos 1 is not supported, but retained messages are. So a new subscription is able to send old messages.
+This feature is disabled by default.
+The default retain parameter of MqttBroker::MqttBroker takes an optional (0 by default) number of retained messages.
+MqttBroker::retain(n) will also make the broker store n messages at max.

-  1.  _BASED moved to template to remove type conversion to long and

-      The print implementation still upscales to long for it's internal
-      print routine.
-
-  2.  _PAD added to allow padding & filling of characters to the stream
-
-  3.  _WIDTH & _WIDTHZ added to allow width printing with space padding
-      and zero padding for numerics
-
-  4.  Simple _FMT mechanism ala printf, but without the typeunsafetyness 
-      and no internal buffers for replaceable stream printing

Richie Vos	14882fed22	Build cleanly under c++14 Other parts of TinyConsole require >= c++ 14, but this forces c++17. That's not necessarily a problem, but it triggered some build warnings for me, so in case that's unintentional I'm sending this diff. Exact warning: ``` Compiling .pio/build/esp32dev/lib4a7/TinyMqtt/TinyMqtt.cpp.o .pio/libdeps/esp32dev/TinyMqtt/src/TinyMqtt.cpp: In member function 'MqttError MqttBroker::subscribe(MqttClient*, const Topic&, uint8_t)': .pio/libdeps/esp32dev/TinyMqtt/src/TinyMqtt.cpp:221:13: warning: structured bindings only available with -std=c++17 or -std=gnu++17 for(auto& [retained_topic, retain]: retained) ``` I personally just switched to c++17 as my fix/workaround.	2023-04-03 20:46:41 -07:00

Richie Vos	ac1eedd72a	More informative error on version mismatch I spent a lot of time debugging my arduino, trying to figure out why my calls were all failing. Turned out to be due to the mqtt cli using v5, while this library only supports v4. By mqtt cli I mean the [hivemq one](https://hivemq.github.io/mqtt-cli/), which is the first one that shows up on google searches. Being new to mqtt this burned me for awhile, so I'm hoping this helps the next person. Both by having this PR show up if they search, and making the error more informative.	2023-02-12 21:37:17 -08:00
