Hi Nomi,

Where did you find the hrs_s110_8_0_sdk_8_0.zip file ?

I tested here and it worked just fine. Please try the bootloader and the DFU file I attached here. Which central device did you use to test ?

If the issue remains, please run the bootloader in debug mode (as described at question F here ). You can check if something went wrong and it can't jump to application. But my test here showed it worked fine.

bootloader - RC4000Temp.zip

ble_app_hrs_dfu_s110_v8_0_0_sdk_v8_0[1].zip

changing to the clock you gave pca10028 will not get out of dfu mode. i changed the clock as you told me in dfu_dual_bank_ble_s110_pca10028 example. Then starting pca10028 in dfu mode i uploaded hrs_s110_8_0_sdk_8_0.zip. But the hrs did not start the board is stuck in dfu mode it is not getting out of dfu. I tried uploading my custom application too but the board still remain stuck in dfu mode. How do i get it out of dfu and start advertising my custom application.?

Hi Nomi,

You should setting up the softdevice with the scheduler, that's how the bootloader configured. This mean you should use SOFTDEVICE_HANDLER_APPSH_INIT. This setting should work:

SOFTDEVICE_HANDLER_APPSH_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_4000MS_CALIBRATION, true);

I verified here on the PCA10028.

On pca kit 10028 dfu dual bank ble s110 does not work with clock RC_250_PPM_TEMP_4000MS_CALIBRATION. It advertises but when i try to upload mu custom application error comes. With clock xtal 20 ppm it works and i can upload my custom applications. I am changing this clock because i dont have crystal on my custom board.

1-On pca kit all codes work with both clocks execpt dfu_dual_bank_ble_s110 with RC_250_PPM_TEMP_4000MS_CALIBRATION. Which advertise nicely but when i connect to dfu to upload my custom application or hrs_s110_8_0_sdk_8_0.zip an already present file in nrf toolbox dfu section from ios app the error comes dfu connection has been last. 2-on custom made as i dont have any crystal so RC_250_PPM_TEMP_4000MS_CALIBRATION works. So first i test my codes on my pca kit then i chage its clock and then transfer it on my custom board. Every thing was working fine until i got stuck on dfu dual bank ble example which works perfectly on pca with XTAL_20_PPM advertises nicely and i can upload my custom applications. But when i changes its clock to RC_250_PPM_TEMP_4000MS_CALIBRATION so that i can burn it to my custom board when i try to upload my custom application dfu connection has been last error comes.

Hi Nomi,

Please be more specific on what doesn't work.

Let me see if I get what you mean:

with pca10028, both XTAL_20_PPM and RC_250_PPM_TEMP_4000MS_CALIBRATION source works
with custom board, RC_250_PPM_TEMP_4000MS_CALIBRATION works but XTAL_20_PPM doesn't work

Is this correct? If yes, do you have a 32KHz crystal on your custom board ? If not you can not use the XTAL_20_PPM clock source

sorry it isnt SOFTDEVICE_HANDLER_APPSH_INIT. I used SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, NULL); . The clock already used in dfu_dual_bank_ble_s110_pca10028 example. But on my custom board my codes work when i change clock to SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_RC_250_PPM_TEMP_4000MS_CALIBRATION , NULL). Now when i change clock in pca10028 dfu does not work.

Hi Nomi, Could you explain why you switch from SOFTDEVICE_HANDLER_APPSH_INIT to SOFTDEVICE_HANDLER_INIT ? Have you also removed the scheduler in the code ?
