Hi BLE fellows,
Following the steps explained here, I have tried to integrate the OTA DFU feature & bootloader from the latest SDK to my application and tested it on my own nRF51822-based hardware, it did not work. To eliminate the uncertainty about the hardware, I did the same with the Eval. Kit and I still encounter the same problem. Until point 8 (Verify that the device is now advertising as 'DfuTarg'), everything works as expected, as the answer of this thread also explains. The problem: I can never see the nRF advertising as "DfuTarg".
What I have changed to adapt the example "ble_app_hrs_dfu" to Eval. Kit, is basically just the LED and Button mapping.
Warm Regards.
