BLESerial nRF

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.

This free version is identical to the Pro version, except it does not include Functions (custom send buttons and toggle switches) and only works with Nordic nRF52 modules — not CC254x boards such as the HM-10.

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.

**WANT MORE?**
Check out BLE Serial Pro — it adds programmable one-tap command buttons, supports HM-10 and CC2541 in the same app, and shows a live console strip so you can see device responses without switching views.

Features:

• Fully customisable console view, with options like:
- Display format (ASCII, Hex, Dec, etc.)
- Line numbers and timestamps
