Task: Add OTA updating to the ble_app_uart example in the nRF5 SDK. Create a Keil project and any necessary batch or python scripts to generate the OTA binary zip. All work can be done using the Nordic Dev Kit for the nRF51 (PCA10028). SDK12.3. Success is achieved when I can compile a project with uart function, run a script of some type to generate some file, then use that file to update the firmware in the PCA10028 Dev Kit using the Nordic app on a phone. It’s ok to press a button, but not ok to cycle the power as part of this. I expect you to take care of all setup for the DFU and provide just a list of programs to install, the Keil project etc, and a script (batch or Python) to perform all necessary steps to generate the OTA file on a standard Windows PC. Right now I am successfully using an edit of examples/ble_peripheral/ble_app_uart/ on my custom hardware. For compatibility with this, the 32kHz LF crystal cannot be used. The edits implement a custom uart protocol which isn’t important here. On this board, the power cannot practically be cycled by the end user. But the other microcontroller in the system can set a particular pin and the nRF51 can reboot itself. Or we can use Nordic’s button-less DFU. The Keil project and all needed files need to live within a directory separate from the SDK directory to make them practical to version control with GIT.

Hi, my name is Sefer and I'm a firmware developer specialized in BLE and Nordics nRF5xxxx chips. I've been working exclusively with these , over the past couple of years. I've implemented DFU-OTA in many projects so this won't be a problem. We can do buttonless DFU in this case, and I will provide scripts for generating the package and/or merging bootloader with application and flashing the chip, as well as detailed description on how to use those. Let me know if you're interested, I've done this many, many times and I could finish this very quickly.

Hi, I have more than 8 years of experience in embedded design and development. I have expertise in IoT products development using WiFi, BLE, GSM, GPS, RF and many more. I have hands on experience in firmware development on Nordic’s BLE socs like nRF51822, nRF51844, nRF52832, nRF52840 etc. I have experience of developing applications using various BLE profiles like peripheral, central, iBeacon, broadcaster, observer etc. I have developed DFU application on nRF52832 Soc. The update was working without any external button. Let’s discuss and go ahead. Thanks.
