I have written custom firmware using Nordic's S132 BLE stack that has custom services and characteristics. I just need the DFU capability added to the existing project which used the Keil IDE. I'd love to have the project converted to the new Segger environment if possible too. I'd like the DFU to be buttonless so that an iOS app (like Nordic's iOS app) can trigger the update automatically. I have working hardware , firmware and even the injection molded final enclosure. I just need the DFU added. The current firmware is actually pretty small so there's lots of flash and RAM available for the DFU. Let me know what you estimate on the cost.

Hi, I would like to offer you my expertise in embedded firmware development. I have done numerous projects which include both nRF51 and nRF52 with DFU bootloader including newer version - Secure DFU. Adding DFU service to your existing firmware is something I can do easily for you especially if you have free ROM and RAM. Also I can prepare tools and instructions how to build new image for DFU bootlaoder, since they changed things a bit and application image has to include secure key now. So you dont have to loose time on that once you will want to make new firmware upgrade. Keil is something I'm very comfortable working with but porting your code to Seggers IDE is also something I can provide you with. Looking forward for your replay, Vladimir.

Hi, my name is Sefer and I'm an electrical engineer, just recently finished my masters thesis on BLE mesh networks with nRF52. I work a lot with nRF52, I've developed firmwares for many different custom made low power devices. I've implemented DFU-OTA with all SDK versions, also I work in Keil and Segger embedded studio. I can get this done and I guarantee your satisfaction. Let me know if you're interested. Just send me a message and we can talk more.
