  • Hi Edvin,

    Thanks for your prompt reply and this guide but they do not answer my question. Yes, I do mean the OTA/DFU updates. Ultimately updating the firmware on our product which is NRF51-based via our custom app. Our app is in Objective-C on iOS. It is not one of your sample apps. I'm fairly familiar with the OTA/DFU process and have programmed many NRF51 chips via this process. We have always used your sample apps that we slightly modified for various purposes. 

    Now we are building out OTA updates in our own app for our customers to use in the field. I am getting the very-cryptic above error. "Error 10: Operation failed" -- what does that mean?
