New version of StmDfuBlue is available on GooglePlay.
The application increase the possibility for communication. Now it can work with BLE bluetooth-to-serial modules which based on microcontroller cc254x.
The switch for selecting bluetooth mode (classic or BLE) is added in select device dialog.
The list of paired devices is replaced with list previously connected devices. I think no needs to show in the dialog different friend's phones or fitness trackers. I also can clear this list and remove a device by click the button X right from device description.
The work of the application is checked with module HM-10
