Mosquitto MQTT as server does not work if no SSL is used

[franki29]

Describe the bug
If I compile your code and try without using ssl to connect to my mqtt server, the server response with a "socket error (unknown) on client"

To Reproduce
Steps to reproduce the behavior:

1. Step1 'compile'
2. Step2 'connect to a none secure mosquitto mqtt server.'
3. See error

Expected behavior
Successfully connection to MQTT server without using ssl

It is working if I change the code to:
#elif defined(ESP8266)
// BearSSL::WiFiClientSecure net;
WiFiClient net;
&
#if (!defined(CHECK_PUB_KEY) and !defined(CHECK_CA_ROOT) and !defined(CHECK_FINGERPRINT))
// net.setInsecure();
#endif

Seems to be a problem using BearSSL::WiFiClientSecure net;

Hopefully fixed now: ee16ad1
Could you please check?

[matthias-bs]

Hopefully fixed in v0.3.3. Please note that either #define USE_SECUREWIFI or #define USE_WIFI must be set.

I would be happy if you could give it a try!

Hi using #define USE_WIFI is working for esp8266.
Only compiling is failing at my side because in WeatherSensor.h you use #include <WeatherSensorCfg.h> at my side I have to change it to #include "WeatherSensorCfg.h"

Hi,

thanks for testing and feedback! #include "WeatherSensorCfg.h" makes more sense, because it contains the sketch specific settings and not general definitions of the library.

In some (but not all) of the examples, there is

#include "WeatherSensorCfg.h"
#include "WeatherSensor.h"

I will see if I can remove the inconsistencies/redundancies.

This also relates to issue #1 and issue #11.

Thank you for pointing this out!

Best regards
Matthias
