This app allows you to easily test your projects that use the HM10 or HM11 Bluetooth to Serial transceiver module.
Can be used with, for example, Arduinos and other microcontroller boards.
Basically this app sends data (ASCII characters) to the HM10 and displays received messages. Optionally a carriage return or line break (or both) can be added to the end of the message.
A pro version, "HM10 Bluetooth Serial Pro", is also available, with many more features to help debugging HM10 projects.
Note: this is not an official JNHuaMao app. Source code can be found on GitHub.
