It connects to your device via bluetooth and allows you to exchange messages (data) with it.

• Easy and friendly user interface
• Bluetooth scanner mode, which shows available devices to connect with additional information such as signal level, available services and device identifier
• Sharing of exchanged messages in image (PNG) or text (TXT) form
• Three messenger styles: pure, coloured text and coloured rows
• Ability to append newline, return or both to sent message
• Informational view, which shows statistics of connection (amount of data sent/received, number of messages and device information)

Fantastic product.

"This app is very simple, but works great. It is more reliable then most other ble apps on the market, and doesn't suffer from the reconnection issue that other apps have where you have to ""forget this device"" every time you want to use it."

Works beautifully with HM-11

If you are an Arduino enthusiast and want to experiment with BLE communication, this app is for you. It is easy to use and gets the job done. Instructions are clear and the app does exactly what it is supposed to.

Best Bluetooth controller I've seen yet

Great app, simple interface, so many possibilities. Perfect for my multi million dollar smart house. Now I can control all of my Bluetooth deceives wirelessly! Thanks for the great app!!!
