## What is nRF Connect for Mobile?

nRF Connect is a powerful generic tool that allows you to scan and explore your Bluetooth Low Energy (henceforth Bluetooth LE, also called Bluetooth Version 4.0+ of the Bluetooth specification) devices and communicate with them.

nRF Connect also allows your iOS device to advertise as a peripheral, with full support of many of Bluetooth SIG adopted profiles.

Additionally, nRF Connect supports Nordic Semiconductor’s Device Firmware Update profile (DFU) capabilities, allowing you to update compatible peripherals!

+ Features:
• Supports DFU on all Nordic Semiconducto-powered devices.
• Supports Nordic Thingy™ from Nordic Semiconductor.
• Scan and discover nearby Bluetooth LE peripherals.
• Filter Scanned Peripherals by Name, Manufacturer, Services (Advertised & Connected) and RSSI Level.
• Parsing Multiple Formats of Bluetooth LE Advertisement Data.
• Live RSSI Chart of Scanned Bluetooth LE Peripherals.
• Complete iPad Support, including Multi-Tasking and Mouse Support as of 13.4.
• Logs: Including BLE Function calls, and Export Function as CSV and Text.
• Privacy-Oriented: Full-Disclosure of Scanned Data, Advertised Data, and User-Performed Actions held by nRF Connect.
• Connecting to Any Connectable Bluetooth LE Smart Device.
• Discovery of Services, Characteristics and Descriptors.
• Read and Write Characteristics and Descriptors.
• Enable and Disable Notifications and Indications.
• Advertising as a Bluetooth LE Peripheral.
• Setting up a Bluetooth LE (Peripheral) Server and Notifying/Indicating back to connected Central(s).
• Low-Fat: nRF Connect for iOS is Very Small, so You Can Always Keep Us With You!

## What do users think of nRF Connect for Mobile?

Overall sentiment: positive

**Pros**

- 🚀 Great product
- 🚀 Very handy
- 🚀 Amazing functionality
- 🚀 Love the technology
- 🚀 Versatile program
- 🚀 Best sniffer on the App Store
- 🚀 Brilliant
- 🚀 Best BLE analyzer by far
- 🚀 Awesome for Bluetooth information
- 🚀 Amazing!
- 🚀 Good stuff
- 🚀 Top notch!
- 🚀 Incredible Tool
- 🚀 Good for ble dev for apple products
- 🚀 Nifty, user-friendly
- 🚀 Awesome app
- 🚀 Very useful
- 🚀 Shockingly good mobile app
- 🚀 Embedded Development Tooling
- 🚀 Fabulous tool, great devs.

**Cons**

- 🐛 Doesn't seem to work on iOS 17
- 🐛 Can't really disconnect from peripherals
- 🐛 New update freezes on launch screen DON'T UPDATE!
- 🐛 Legacy DFU not working
- 🐛 Hitting terrible bug
- 🐛 Broken
- 🐛 The RSSI filter doesn't seem to work
- 🐛 Won't find my OBDLink MX+
- 🐛 Broken
- 🐛 Data is reading too slowly!
- 🐛 Useful but slow
- 🐛 Don't download update if you need device logging

**Commonly reported bugs**

- Can't read data from Bluetooth device
- Tries to ask for Bluetooth connection when Bluetooth is off. Asks to connect to devices when Bluetooth is off. Who knows what this app is doing in the background without permission?! What ever it is , it ain't good
- Tapping "tabs" doesn't work (nothing changes in the UI). To get some response from tapping UI controls typically requires (a) launching nRF Connect, (b) switching to another app, (c) switching back to nRF Connect. I've tried uninstalling and re-downloading. Same result. This used to be the bee's knees of BLE tools but it's only worth 1 star at the moment (v2.7.11).
- Cant go past the initial announcement. The app is unresponsive to the taps.

**Most requested features**

- Where's the mac addresses
- Max rssi limit
- Log view
- We need macros in iOS version

Für alle, die mit Bluetooth LE arbeiten oder einfach nur Bluetooth-Probleme diagnostizieren möchten, ist nRF Connect ein unverzichtbares Werkzeug. Die App zeigt zuverlässig alle BLE-Geräte in der Umgebung, ermöglicht das Verbinden, das Auslesen von Services und Characteristics und hilft enorm dabei, Fehler einzugrenzen.

Mir hat sie heute dabei geholfen, ein vermeintlich defektes Messgerät als völlig funktionsfähig zu identifizieren. Das eigentliche Problem lag in einer veralteten Hersteller-App – ohne nRF Connect hätte ich vermutlich unnötig weiter nach einem Hardwarefehler gesucht.

Übersichtlich, schnell, stabil und dabei kostenlos. Genau so sollte eine Diagnose-App aussehen. Absolute Empfehlung – nicht nur für Entwickler, sondern auch für technisch interessierte Anwender und Smart-Home-Enthusiasten.
