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+

The App is great and very easy to use. The customisable keys are a real bonus for frequently used command strings. The only problem is the "auto scroll to end of buffer" feature does not seem to work. Whether of not the box is checked, when new data arrives the start of the buffer is displayed. It makes it really difficult to watch what data is arriving.

I have donated as this App is ideal for what I wanted - remote control stepper motors to drive camera tripod head. The only improvement would be to only show some of the buttons and increase their size. I only want 5 and would be easier to pick. Not only that my Android One mobile would not connect to the HC-06 Bluetooth module but this App did! I suspect because there is an LTE option my mobile is trying to use that and the module is not compatible. Great job
