Bluetooth TCP Bridge

Marek Masár

About this app

OVERVIEW
This app enables communication between devices that use different communication technologies. With this app, your smartphone acts as a protocol converter and creates a communication bridge between remote devices that cannot communicate directly.
Currently supported:
- Classic Bluetooth: Bluetooth modules (HC-05, HC-06), other smartphone running Bluetooth terminal apps, PCs or any other device capable of opening Bluetooth serial port. The app can also create listening port for incoming connections
- TCP server: creates listening TCP server socket to which you can connect up to 3 clients
- TCP client

Available for testing / fully supported in PRO version:
- BLE (Bluetooth low energy / Bluetooth 4.0) : devices such as BLE Bluetooth modules(HM-10, MLT-BT05), smart sensors (heart rate monitors, thermostats, etc.)
- USB-serial devices: supported chipsets: CP210x, CDC, FTDI, PL2303 and CH34x
- UDP socket
- MQTT client

UNSUPPORTED
- Bluetooth speakers and headphones
- Some variants of listed chipsets with suffix in the name (like PL2303G, PL2303A, etc.) may not be supported

FEATURES
- Built-in packet terminal
- Real-time data logging
- Send data directly from the app to connected devices
- Bridge traffic between any two supported protocols
- Ideal for testing, debugging, and integrating custom hardware

Ratings and reviews

Doesn't work, doesn't connect to any paired USB device. Also, the PC/Windows version which I think is the TCP server (not specified in the manual anywhere) is a paid product, I'm not gonna waste my money on something that doesn't work.

Worked straight away, no messing around! Intuitive interface. I love the logging that shows you exactly what's going on. I used the app to send Bluetooth data to a TCP client.

Exactly what I needed to connect to raspberry pi shell over bluetooth. Thanks!
