Bluetooth Terminal

Bluetooth Terminal is a simple tool for talking to Bluetooth Low Energy (BLE) devices: Arduino and ESP32 boards, HM-10 and other serial modules, sensors and your own prototypes.

FIND AND CONNECT
• Scan for BLE devices nearby and see their signal strength
• Connect with one tap and see the connection status at all times
• Clear error messages when a device doesn't respond or the connection is lost

TERMINAL
• Send text to the device and see what it sends back
• Sent and received messages are shown in one conversation
• Common serial profiles are detected automatically: Nordic UART (NUS), HM-10, FFF0 and Microchip

SERVICES AND CHARACTERISTICS
• Browse the services and characteristics of the connected device
• Choose which characteristic to send to and which ones to listen to
• Read a characteristic's value on demand

PRIVATE BY DESIGN
• No ads, no account, no tracking
• The app has no internet access: your data stays between your phone and your device
• Location permission is not needed (Android 12 and newer)

Requires Android 12 or newer and a phone with Bluetooth Low Energy. Bluetooth Classic (SPP) devices such as the HC-05 are not supported yet.
