Hi Guys,
since yesterday i am trying to get the DFU with Softdevice S110 (BLE) v7-alpha3 working but haven't succeeded yet. My process is the following:
- s110_nrf51822_7.0.0-3.alpha_softdevice from nordic website downloaded
- softdevice programmed to nRF51822 (256kB/PCA10005) with nRF Studio v1.17.0.3211
- dfu example provided with the new soft device compiled using KEIL (SDK 5.2 installed on my computer, changed not a single line of code in the example)
- flashed dfu boot loader using KEIL (down)load button
The nRF side should be ready/fine now, right?
- launching nRF ToolBox app/DFU part on my iPhone 5S
- i can see and choose the Dfutag device
- last but not least i chose ble_app_hrs.hex and press UPLOAD
Some times it displays the progerssbar (empty) and shows "init" beneath it and sometimes just the progress bar but i always get an error after roundabout 30seconds.
I also tried to debug it with breakpoints in the app_error_handler but never get here. My questions are know:
- is my process correct the way described above?
- is there any getting-started guide or so?
- any suggestions what i could try else?
- Do i have to change something in the source code?
Kind regards Marius
