Application for working with TMD-x and SMkey duplicators.
Creating and sending key codes to a duplicator, receiving read codes, saving to the database, searching for crypto keys in Mifare Classic tags.

Supported devices: SMKey, TMD-3R, TMD-5R, TMD-5S, TMD-5RF, TMD-RW15, RFD-4, RW-Megakey.
Possibility of exporting records to Megakey, and setting parameters of TM01A keys through the duplicator TMD-3R, TMD-5R, TMD-5RF.

For devices without Bluetooth, a connection via a USB-OTG cable is required.
To work with SMKey and TMD-5S, support for Bluetooth 4.0 or higher is required.

To work with the duplicator, simply launch the application. No need to make any pairings.
If the application does not connect to the device, check whether location is disabled. The program does not use geolocation, but the way it works in Android is that blocking geodata blocks the operation of Bluetooth using the BLE 4.0 protocol
If the application still does not connect, turn off Bluetooth​, delete the application, install it again and run it. Answer yes to the question “Allow the application to turn on Bluetooth​.”
