@Phu: Please explain me how you test the bootloader ! With step by step on what you do. It's hard to guess from your video. The default steps should be:

1. Flash S120 softdevice
2. Flash the bootloader
3. Check if the bootloader advertising
4. Use MCP or DFU app to do DFU with the image from an example in the SDK. 
5. Check if the DFU process finishes successfully
6. Check if the device enters the application 
7. Check if you power reset the device and still can enter application.

You can test first with simple application like blinky (with modification on ROM so that it works with S120 flashed). Let me know at which step you have issue.

@Phu: After you flash the bootloader, please check and make sure it's advertising as DFU_Targ. It's not the default procedure that you flash your application via KEIL unless you modified the APP_VALID flag.

I suggest you to modify the bootloader so that you can debug it and check what goes wrong by stepping into the bootloader code. To set the bootloader so that you can debug it, you can have a look at question F here.

What kind of issue did you have with the stock S120 bootloader example ?

@Hung: I am a beginner in nrf81822, and I tested as a normal way, first I used NRF Studio erase all chip then I programed S120 V2.0.0 for SoftDevice, then I program modified bootloader file (this file work well in s110 and I modified it to use on s120 follow devzone.nordicsemi.com/.../), then I use KeilC V5 to program my application. But when I debug my application, program canot jump to main beacause It's halted at 0x000006d0). And I tested your bootloader on SDK 8.0.0 too but there's this issue. Do you have Skype Account, if you have time, can you contact Skype with me through quangphu1799@gmail.com? We can discuss easier. Thank you so much.

@Phu: Could you described how did you test ? Did the bootloader advertise and you can connect to it ? Have you tried to test with my bootloader ?

Hi Hung Bui, First , I have a bootloader file of s110, and it works perfectly on s110, but in my new project, I want to use this file to work for s120, I modified this file follow this devzone.nordicsemi.com/.../, then I text for its work on example of SDK 8.0.0, use s120 v2.0, but when I debug, program is halted at 0x000006d0. I downloaded your example on above link, but It still has this issue. I use PCA1001.

Hi Phu,

Could you let me know how did you test ? You mentioned at the beginning about the bootloader but it's not related to the ble_app_hrs_c ? Did you managed to update the firmware to ble_app_hrs_c ? Which S120 version you used ?
