nRF5_SDK_11 BLE DFU Bootloader - won't advertise

[eboris]

Ok - I'm trying to get my arms around this bootloader process.

I am using the nRF5_SDK_11.0.0_89a8197 SDK along with the PCA10040 develeopment kit. I also am using IAR tools.

Following the example for BLE DFU I did the following:

1. Erased the device using nRFgo Studio - works.
2. Programmed the SoftDevice using nRFgo Studio- C:/nRF5_SDK_11.0.0_89a8197/components/softdevice/s132/hex/s132_nrf52_2.0.0_softdevice.hex This woked as well.
3. Programmed the BLE DFU Bootloader using nRFgo Studio. I built the IAR project supplied (C:\nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10040\dual_bank_ble_s132\iar) . It built fine. I was not sure how to program the bootloader using IAR so I used the nRFgo Studio tool to program the generated output file. It programmed fine.
4. At this point I expected to see the device advertising the DFU service. It doesn't. LED1 is ON solid. LED3 is ON solid. There is not advertising going on.
5. At this point I suspected that there was something wrong with my generated BLE DFU Bootloader file. So I decided to use the pre-canned that came with the SDK. When I tried to program the BLE DFU Bootloader using nRFgo Studio - it complains that the provided file contains data that is addressed to go in the SoftDevice area. The file used is: C:\nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\hexdfu_dual_bank_ble_s132_pca10040.hex

So really - there's two issues here. I'm sure there is something simple that I'm doing wrong. Ideas?

@Eboris: If you use nRFGo Studio, Erase All, then flash the dfu_dual_bank_ble_s132_pca10040.hex with bootloader tab, it should work.

When you test using the C:\nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10040\dual_bank_ble_s132\iar, 2 LEDs turned on. It sounds about right, I don't know why you can't find it advertising. Could you double check ? Make sure you flashed the correct softdevice.
