Ratings and reviews

An excellent app with a simple interface that I found to be very intuitive. I had it up and running in minutes just by exploring the menus. The macro functionality is especially useful when debugging custom Bluetooth protocols, allowing complex command strings and control characters to be entered quickly. I've only used it for single connections (this terminal to one Bluetooth widget) so I cannot comment on how it behaves in a more complicated environment. But for HC-05 / HC-06 development it is an essential tool for me. No ads. No crashes or glitches. It just works. I liked it so much that I made a donation to the developer. A+

It worked really well to an HM-10 modem. The PIN entry worked, auto rotate worked, the received text stayed on screen after the modem disconnected. It correctly decoded and displayed the extended ASCII character I needed to send (⁰)

urgent!!! please include a pause button for the data being displayed, the transfer and logging must continue in the background, just the displaying needs to be paused for analysis.
