+## TCP bridge method
+^[Top](#top)
+
+Termux doesn't come with usb serial neither bluetooth serial drivers.
+However, it is fully integrated with phone's network, so we need to talk to the proxmark using serial to tcp sockets (carried out by android apps).
+
+### USB connection
+^[Top](#top)
+
+### USB-UART Bridge Application
+^[Top](#top)
+
+Install [this free app](https://play.google.com/store/apps/details?id=com.hardcodedjoy.tcpuart) on the Play Store
+
+### Setting up usb socket
+^[Top](#top)
+
+The app lets you choose the baudrate. Default value (115 200 baud) is fine.
+Plug the PM3 in and click connect.
+Set the toggle in server mode and choose a random port not used by system (e.g. 4321) and start the server.
+
+### Bluetooth connection
+^[Top](#top)
+
+### BT-UART Bridge Application
+^[Top](#top)
+
+Install [this free app](https://play.google.com/store/apps/details?id=masar.bb) or [the paid version](https://play.google.com/store/apps/details?id=masar.bluetoothbridge.pro) (which includes usb bridge)
+
+### Setting up bt socket
+^[Top](#top)
+
+You need to pair the proxmark3 in the Android settings.
+In the app choose your registred PM3 device as 'device A'.
+Select TCP server as 'Device B' and choose an unused port (e.g. 4321).
+Ensure 'Retransmission' is set to 'both ways'.
+
+### Termux connection
+^[Top](#top)
+
+Start a new session, then:
+```
+proxmark3 tcp:localhost:<chosenPort>
+```
+Alternatively, if you have made the client in the git repo:
+```
+./client/proxmark3 tcp:localhost:<chosenPort>
+```
+ENJOY !
