Hi Nordic Team,

I am using board PCA10040 wtih nRF52832 SDK 11.

I have Added DFU code to ble_app_hrs_freertos example. Once I will go for DFU from nrf Mobile Application, nRF board is not jumping to bootloader. I am using Default Bootloader and softdevice.

NOTE: I have Tested the DFU without FreeRTOS, DFU is working good.

Please let me know what is the issue in FreeRTOS example for DFU. Is it any Open issue regarding DFU in FreeRTOS ?

Please Let me know ASAP.

Hi Rudra,

there are some known issues with freeRTOS and DFU in SDK v11.0.0, see the EDIT 6/5-16 : Added "buttonless" example based on SDK 11.0.0 (production) in this answer.

Best regards

Hi Bjorn,

Thanks for the Information on Updated code. I have downloaded nRF5_SDK_11.0.0_freertos_dfu_060516.zip file and I tried to do DFU, its working good. Now, I am trying to add NUS service in it. But after compile and flashed, I am not able to see any of the Advertising behavior.

I don't know what is gone bad, Please let me know if you have done NUS in nRF5_SDK_11.0.0_freertos_dfu_060516.zip this code.

Thanks, Rudra Sagar

Can you debug the project and set a breakpoint in app_error_handler_bare() in app_error.c? If the breakpoint is hit, then take a look at the call stack to see where the error came from and report it here.

But that answer is for board PCA10040 with nRF52832 , it's the same issue with 51822? I'm using SD130 v2.00 with SDK11.0. Thanks in advance.

Yes, the source code fixes should be applicable to the nRF51 as well. However, I recommend that you move to the latest SDK version, i.e. v12.2.0 where many of the FreeRTOS issues have been fixed.

No, I've tried it and can not work, I use keil 5.23 . There's no freeRTOS with dfu project in SDK12.3.0. Can you send me a project use FreeRTOS with dfu for 51822QFAC. Our product need to be massed production in September.
