+## Over The Air Firmware Updates
+Any updates to the application software can be done over Bluetooth using Over The Air Device Firmware Update (OTA DFU). This tutorial will use Adafruit's Bluefruit Connect app, which is available for iPhone and Android.

+You will also need two files to upload which Arduino makes when. One is the `.hex` file, The other is a `.dat` file. The latest version of our Tympan Radio firmware is published as a release on this repository, which you can download [HERE](). Both of these files need to be accessible on the phone, or tablet, that you intend to use to perform the OTA DFU. When you have the files on your mobile device, open up the Bluefruit App, and connect to the Tympan that you want to update. Each Tympan advertises it's name followed by a unique ID. Click on connect.

+There is a long list of updates that are for Adafruit's BLE products. Scroll all the way to the bottom and select Custom Firmware.

+The pop-up window will ask you to choose the Hex and Init files. Navigate to the place where you have stored the files you downloaded from our latest release. Choose our hex file for the .hex, and our dat file for the Init file.

+That's it! After successful upload, your Tympan Radio will be running the latest and greatest firmware version. If you want to continue to use the Bluefruit App, it is advised to close the close it after the upload process is complete, and then restart if you intend to use it again right away.

 The blank nRF52 module is programmable using the j-Link connection on pins SWO, SWCLK, SWDIO, RESET, 3V3, and GND. Those module pins are broken out to a header row on the bottom of the board. See connector J7 in the schematic, and the 6 SMT pads on the back layer of the PCB design.

-## Over The Air Firmware Updates
-Any updates to the application software can be done over Bluetooth using Over The Air Device Firmware Update (OTA DFU). This tutorial will currently cover one method for doing this, using Adafruit's Bluefruit Connect app. You need two files to upload which Arduino makes when you click on `Sketch > Export Compiled Binary`. One is the `.hex` file, The other is a `.dat` file. The `.dat` file is contained inside the compressed `.zip` file that was also produced by the compile binary command. Unzip compressed folder, and find the `.dat` file inside of it. Both of these files need to be accessible on the phone, or tablet, or computorb, that you intend to use to perform the OTA DFU.
-
-**NOTE: Your Sketch MUST include the following code to ensure that OTA DFU is persistent!
-After your #includes on the main .ino tab activate the DFU Service
-`BLEDfu  bledfu;`
-then, during the setup() turn on the OTA DFU Service
-`bledfu.begin();` Check out the code in TympanRadio_baseFirmware.ino for how it's done.**
-
-In the Bluefruit Connect App, search for and connect to your Tympan board. Select Updates then scroll all the way down to the USE CUSTOM FIRMWARE button way down there, and press it. You will be prompted to find a "Hex File" and an "Init File". The "Hex" is the `.hex` and the "Init" is the `.dat` that we discussed in the previous paragraph. Then press "Start Update". The process can take some time, but there is a status bar that should animate the progress. 
-
-It is advised to close the Adafruit App after the upload process is complete, and then restart if you intend to use it again right away.
 
 ## Compiling the Firmware
 Ideally, you do not need to compile the firmware; you would just use the pre-compiled HEX file already included with this repository.  But, if you do need to re-compile:
