B4R Tutorial 2 basic projects on esp : one with MQTT client and one with MQTT broker

it is just 2 basic projects to do some tests with MQTT
we have no personal data in projects, full provisioning is done by a Web server interface

one basic project is with Wifi and MQTT client
Wifi and MQTT are configured by interface of a web server
data are stored in eeprom, with management of errors (no data, more data than needed)
Wifi and MQTT client will restart automatically in case of network issue

one basic project with Wifi only and a MQTT broker
Wifi is configured by interface of a web server
data are stored in eeprom, with management of errors (no data, more data than needed)
Wifi and MQTT broker will restart automatically in case of network issue

if you install one or more projects MQTT client and one MQTT broker, you can do MQTT testing in your network.
