/*
* 22. MQTT + Mosquitto in LAN test
*
* Briefly:
* 1. Pub every 1 sec Analog && Digital values only:
* sta/analog/0 - A6/PA6
* sta/digital/0 - SW1/PC5
* 2. Pub every 10 sec Uptime && FreeRAM device statistic:
* /w5500_avr_dbg - Uptime: xxxx sec; Free RAM: xxxx bytes
* 3. Sub: Print out all received messages
* 4. On lost connection with MQTT broker reboot device after ~ 20 sec.
*
* Used as base code from:
* Nadyrshin Ruslan - MQTTPacket (MQTT client/server v3.1.1 adapted for AVR MCU).
* YouTube-channel: https://www.youtube.com/channel/UChButpZaL5kUUl_zTyIDFkQ
*
* Author of unofficial porting to AVR Mega1284p/644p + W5500 Ethernet NIC (Wiznet sockets library using without Arduino):
* Ibragimov Maxim aka maxxir, Russia Togliatty 05.04.2019
