## What is MQTT Probe?

MQTT is a lightweight messaging protocol which can be used for IOT applications for small sensors and mobile devices.

If you are here, you probably know what this app is for. It's a simple MQTT connection testing tool. It allows you to do everything that you need to do to debug an MQTT connection. You can connect to a MQTT server, publish messages with qos control and subscribe messages too. What makes this app stand out is that you can save away topics and messages with tags that you can remember, rather than typing in large text every time. You can also save away the connection details so that you can pick the parameters easily next time.

New features will be added on request.

### 1/5 — Ads, no SSL

*2017-11-20*

Worst ads I have ever seen on an app, no SSL/TLS support. Popup ads make it unusable.

### 2/5 — Ads....many Ads

*2017-08-22*

I understand the need for ads but do not subscribe to the way they were incorporated

### 1/5 — Totally Useless

*2017-06-30*

You can't even perform any mqtt or anything at all. Whenever you click connect button, the same Ad pop up. You can't even connect. The whole app is designed to show that same Ad. Totally useless.
