MQTT problem with ST BLE Sensor App on Android

[antoineboisson]

Hello everybody,

I am studying electronic engineering in Toulon, France, and I need to use the ST BLE Sensor App for a project using Activity Recognition, for which I have to send data to a MQTT broker. My problem concerns the connection to the MQTT broker with the Android version of the app. The URL of the broker I use is not recognized by the app, so that I cannot establish the connection with the broker (see screenshots).

I precise that I have not this problem with the iOS version of the app, everything works well.

Does somebody have a solution to use the Android version of the app for my project?

Thank you very much in advance for your help.

Best Regards, Antoine
