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!

What’s New

Version 2.1

Here it is! The big release you were waiting for with… roll of drums please… DARK MODE !

# Features

• Full Adoption of iOS 13’s new Dark Mode across the app
• Refined the Scanner’s color palette under iOS 13 to use Apple’s new system colors
• Improved design of the Settings Screen in iOS 13 (use of inset_grouped style)
• Introduced Apple’s new SF Symbols when running under iOS 13
• Redesigned Settings’ Screen under iOS 13
• Automatic Advertiser Naming
• Added an extra ‘Configuration’ Section in the Advertiser’s Screen to inform the user that the Advertiser’s AdvInterval and TxPower levels cannot be set manually, and that iOS promises to advertise in a ‘best effort’ manner.
• Service Characteristic Descriptors are now scanned, parsed and shown to the user.
• Added Support for Properly Parsing all four Eddystone Frame Types (UID, URL, TLM and EID) and Eddystone UUIDs.
• The “Package Selection” DFU Screen now detects Folders, and orders the list of shown elements prioritizing ZIP files.
• The “Ready to Upload” DFU Screen’s now pipes the DFU process logs into its Text Element.
• The “Ready to Upload” DFU Screen now allows Sharing/Exporting the contents of the DFU Log.
• New “Error” State added as part of the DFU pipeline, allowing the user to see the logs of the DFU Update if it fails.
• Device Beacon Data is now parsed instead of computed on-the-fly, so it can now be seen as part of the Scanner State (Settings -> Privacy -> Scanner State)

# Fixes

• Logic: The Device Switcher UI just above the TabBar was not switching properly between all of the selected devices.
• Logic: If the same Label and Image UI Component was shown multiple times, it’d throw off the Animation’s timing.
• Crash Fix: If a DFU Update failed and the user toggled the visibility of the Device Details pane, it would previously leave the App in an inconsistent state regarding the selected device, causing a crash.
• UI: The colors you saw in the lists of scanned devices in both the Scanner and Graph tabs were "supposed" to look random, but weren't.
• UI: When Disconnecting from a Device, the Action Buttons now Disappear.
• UI: More things that don't fit here!
• Performance: Drastically improved battery consumption of the Graph Tab (50% reduction)
• Performance: Unified Threading Pipelines for the Event, Filesystem and BLE subsystems, freeing up the Events pipeline to listen to the user faster as well as greatly reducing the chances for the app to cause a Thread Explosion.
• Performance: Disk writes of the App’s state-changes have now been removed from the main Event queue and passed on to the Filesystem queue, making the app perform faster since all State and Logic changes can be performed without waiting for disk writes.

That's it for this week, folks! We’re working hard already on our next release. See you then ;)
