BluetoothUSBTCP Bridge app enables communication between different types of communication technologies. Smartphone with this app installed acts as a converter device. It connects to remote devices which cannot communicate directly between each other, and it creates communication bridge between them, enabling them to exchange data. Following types of connections are currently supported:
 : devices such as Bluetooth modules (HC-05, HC-06), other smartphone with Bluetooth terminal app, PC or any other device capable of opening Bluetooth port (serial port profileSPP). App can also create listening port to which remote Bluetooth devices can connect.
 :  devices such as BLE Bluetooth modules(HM-10, MLT-BT05), smart sensors (heart rate monitors, thermostats...)
 : supported: CP210x, CDC, FTDI, PL2303 and CH34x chips
 : app can create listening TCP server socket to which you can connect TCP client running on remote device
 : app can connect to listening TCP server
BluetoothUSBTCP Bridge app can also display all received data in log in hexadecimal or text form. From v3.1 it is also possible to send data directly to connected devices from the app (0x or text form).
 - Click ConnectListen and select device from the list of paired devices. Make sure other device is listening for incoming connections. You can also initialise connection from remote device. In such case use long click on ConnectListen button which creates listening SPP port.
 - When BLE device is selected, app starts scanning for nearby BLE devices. Select your device in the list of found devices.  Characteristics and services are retrieved automatically. One characteristic can be used for receiving and transmission (one Rx+Tx characteristic), just click on characteristic which you want to use.
 - Your phone must support USB OTG function. Some phones detect more than one USB device, in that case you need to try which one is the correct one by changing parameter USB#. Following parameters are supported: Baud rate[bps], data bits, parity, stop bits, flow control. Flow control is implemented for CP2102, FTDI and CH34x chips. 
 - App can create listening TCP Server socket. You can connect to it from remote device using TCP Client. Make sure your firewall allows such connections. This version allows connection of one TCP client.
 - App has also TCP client, which can connect to listening TCP server. As usual, you just need to specify server IP and port number.  In case of connecting to PC make sure firewall is set up properly.
Unfortunately, devices like headsets and Bluetooth speakers are not compatible with this app, since they use different Bluetooth profile, neither SPP (serial port profile), nor BLE (Bluetooth Low Energy).

    1 star because I don't manage to use it yet, I'll edit the rating once I find a solution. I have a Skywatcher EQM-35 pro mount and a smartphone (Huawei P30 pro) with USB C. I bought a USB B to USB C cable and linked directly the phone to the USB B plug in the hand controller. The app manage create the TCP server but fails in second step when connecting to a USB device. USB in found (1) but fallowing error message appear : "Cannot connect to selected USB device" and "Device initialization failed. Check selected USB#". The mount was polar + 3 stars aligned and switch on in home position when I plugged to phone to the hand controller. Any clue ? Thanks, Daniel

    Although Stellarium sees usb comm port and tries to connect directly to scope via comm port always fails. Installed this app and now it works great Thank You! Not sure why this "bridge program" is needed but makes scope control work!

    Never be happier with a $1.49 purchase on anything, especially the Play store! Thank you for a no BS, straight, clean app that just works! Solved a simple problem that wasn't so simple with no plan B for this particular mobile test rig. I just thought "maybe there's a serial port bridging app for Android?" Low and behold, here it is!

    "I needed it to connect my Meade telescope to the Stellaruim App on my phone. The connection goes from a serial port to a USB converter to the App. Pro BT/USB/TCP does the USB and TCP part excellently!" Not anymore ! in Ver. 3.3 I cannot edit the IP address ? The default is and I keep on losing my connection. I have a Samsung S9 with Android 10 using a USB to serial connection to control a Meade telescope but it keeps on losing connection, if restart the USB device it works

    I'm trying to bridge android to arduino. I can't set Bluetooth baud rate. Also, it just feels like there is lack of options/information. What is the baud rate used by bt module and can I change it?

    completely useless, cant connect anything to the app, even having tested by connecting 2 bluetooth units, headphones and bluetooth speakers to phone, shows it but won't connect, dont buy waste of money
