The dedicated serial terminal for Nordic nRF52 Bluetooth Low Energy boards. BLE Serial nRF52 connects your iPhone or iPad directly to any nRF52-based device and lets you send commands and receive data in real time — no cables, no adapters, no fuss.

Built specifically for the nRF52 UART service (6E400001), it works out of the box with popular nRF52 development boards and custom firmware alike.

CONNECT IN SECONDS Scan for nearby nRF52 devices and see their name, advertised services, manufacturer data, and live signal strength at a glance. Tap to connect. Auto-reconnect brings you straight back to your device every time you open the app.

SERIAL CONSOLE A smooth scrolling console displays all incoming and outgoing data, with sent text highlighted for easy reading. Adjust font size, line endings, and display format (ASCII or hex) to suit your workflow.

SMART ALERTS Set text patterns to watch for in incoming data. When a match is found, the app notifies you immediately — ideal for monitoring autonomous devices or catching error conditions.

FULLY CONFIGURABLE The service and characteristic UUIDs can be adjusted in Settings for custom nRF52 firmware. Supports both standard and 128-bit UUIDs.

CLEAN AND FOCUSED No ads. No subscriptions. No unnecessary permissions. Just a fast, reliable connection to your nRF52 hardware.
