Description
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
