This app supports different bluetooth versions:
- Bluetooth Classic
- Bluetooth LE / Bluetooth Low Energy / BLE / Bluetooth Smart

This app supports different bluetooth devices:
Bluetooth Classic (implementing standard Bluetooth SPP profile):
- HC-05, HC-06, ...
- Raspberry Pi 3
- ...
Bluetooth LE (implementing vendor specific Bluetooth GATT services):
- predefined:
* Nordic Semiconductor nRF51822, … (e.g. BBC micro:bit)
* Texas Instruments CC254x (e.g. HM-10, CC41-A, … modules)
* Microchip RN4870/71, BM70/71 'transparent UART service'
* Telit Bluemod
- custom profile:
* Texas Instruments CC2640 serial service, except config characteristics
* Silabls BLE113
* uConnect BLE serial adapter
* ...

All features in this app are free. In-App purchase is only used for the 'Donate' option.

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+

Simple and efficient. No problems with hanging or crashing. I tried a few paid apps before this and they had too many problems to be useful. Only thing I would wish this had was a way to parse simple delimiter separated ascii text or numbers from the stream into a dashboard of sorts. I use this to monitor my Arduino projects which output the current status through serial, and a second page with a grid to display the separate values in bigger font would be ideal.

Works great with HC-05 transceivers (for Arduino) which use Bluetooth BLE rather than "old-style" Bluetooth. Other apps I tried could only connect with old-style Bluetooth devices, not the HC-05.
