MQTT Over GPRS with SIM800C

[mdonalisio]

I have a problem with this configuration, because PubSubClient Lib close connection from broker when i connect Yellow and Green, I am using TinyGSM for Gprs, over 2G, library and PubSubClient for Mqtt Client, but all work fine without using dscKeyBus Library but, when i using this library, the connection with broker is close in random time. I Only call dsc.begin() and dsc.loop(). And i using ESP32

Thanks
