MQTT gateway - MQTT connection status

[pgeens]

Hello to all, I have successfully set-up a MQTT gateway. Now i'm trying to expand my gateway with a LCD screen in order to display some relevant statusses. I was wondering how I can e.g know if the MQTT connection is ok or not not - you can see this if you enable debugging mode but this is too much info to display on the lcd (and not that user friendly)

If you are using pubsubclient, then

bool PubSubClient::connected()

should do the trick

@lood29 said in MQTT gateway - MQTT connection status:

bool PubSubClient::connected()

Did not work like this: it works with if (!_MQTT_client.connected()) {
