Got someone MQTT on the Electron running? It seems it can’t connect to my broker. The same code runs on the Photon and RedBear Duo without a problem. Ok the problem seems to be related to the usage of UDP where MQTT needs TCP to run properly. So the question is, is there a MQTT-S library available…

So I’ve tried the MQTT library from github ( https://github.com/hirotakaster/MQTT ) which works fine with the photon and which makes use of the TCPClient but it doesn’t connect to any broker, I’ve tested public brokers and also my own one without any success.

@jpmens That’s great news! This was not supported earlier. There is an official (I think) Arduino MQTT library as well. I use it with the Photon and it works just as well as the PubSubClient. I haven’t had the time to upgrade my Electron to v0.5.0-rc.1. If you have the time and don’t mind trying it…

MQTT and v0.5.0-rc.1 work with the electron 3G model - however the 2G model does not.

We did our tests with the 2G model; works fine.

I’ve been playing around with MQTT and Photon to get ready for the Electron… I just got the Electron and flashed, serial, right out of the box the same code successfully working with the Photon. Went into Safe Mode… updated firmware, to v0.5. 1f… reflashed, serial, works good! Has any analysis be…

Could you post the code for a simple MQTT topic post? Want to try on an Electron.

Have a look at my posts …I’ve posted two mqtt … variables that work
