I'm looking for a good firmware engineer that can take my current firmware and add the buttonless DFU to it. I currently use the Keil environment but am open to switching to other environments (GCC, Segger...). We can discuss details of payment, timing, and requirements after we talk.
The current firmware can communicate to a custom iPhone app and it also has a custom service for buttons and LED brightness values and the BAS service. It's pretty simple and works very well. It just needs the DFU added. If you can also do iOS apps, I would like the current DFU in the custom app to be able to support the new DFU that you will implement. It's running on a custom PCB and is already inside of a custom injection molded enclosure.
