# IOS-nRF-Toolbox The nRF Toolbox is a container app that stores your Nordic Semiconductor apps for Bluetooth Smart in one location. The current version is 3.0. New in 3.0 version: * The application uses DFU Library, instead of having it's own implementation. See [IOS-DFU-Library](https://github.com/NordicSemiconductor/IOS-DFU-Library). New in 2.5 version: * Refreshed Look & Feel * Better user experience in DFU and UART profiles * Bug fixes It contains applications demonstrating Bluetooth Smart profiles: * **Cycling Speed and Cadence**, * **Running Speed and Cadence**, * **Heart Rate Monitor**, * **Blood Pressure Monitor**, * **Health Thermometer Monitor**, * **Glucose Monitor**, * **Proximity Monitor**. ### Device Firmware Update The **Device Firmware Update (DFU)** profile allows you to update the application, bootloader and/or the Soft Device image over-the-air (OTA). It is compatible with Nordic Semiconductor nRF5x devices that have the S-Series SoftDevice and bootloader enabled. From version 1.5 onward, the nRF Toolbox has allowed to send the required init packet. More information about the init packet may be found here: [init packet handling](https://github.com/NordicSemiconductor/nRF-Master-Control-Panel/tree/master/init%20packet%20handling). The nRF Toolbox 3.0 is using the DFULibrary framework, available here: [IOS-DFU-Library](https://github.com/NordicSemiconductor/IOS-DFU-Library). The library is required to compile the project. Please, follow the steps in this repository to add it to the project. The DFU has the following features: - Scans for devices that are in DFU mode. - Connects to devices in DFU mode and uploads the selected firmware (Softdevice, Bootloader and/or application). - Allows HEX or BIN file upload through your phone or tablet. - Allows to update a Softdevice and/or bootloader and application from ZIP automatically. - Pause, resume, and cancel file uploads. - Includes pre-installed examples that consist of the Bluetooth Smart heart rate service and running speed and cadence service. ### Note - iPhone 4S or newer is required. - iPad 3 or newer is required. - Compatible with nRF5x devices with S-Series Softdevice and DFU Bootloader flashed. - nRF51 and nRF52 Development kits can be ordered from http://www.nordicsemi.com/eng/Buy-Online. - The SDK and SoftDevices are available online at http://developer.nordicsemi.com.
