BL600 NUS service and DFU support

[sowmya]

Hello,

I am using BL600A module and Nordic softdevice and SDK9.0. The system is having NUS service and TX and RX characteristic. Now I have a requirement for firmware upgrade OTA.

My question is, Can I use DFU and bootloader without affecting the NUS service and its characteristics to upgrade the firmware?

How it can be done?

Regards,

No, it is not coming to main. Arguments for the external tool is --family NRF51 --program "#H" and the address is as below:

Update: This is a screenshot after debugging. Hex file is : nrf51422_xxac.hex Axf file: nrf51422_xxac.axf

This is the hex and axf file after changing the RAM registers: nrf51422_xxac.hex nrf51422_xxac.axf

This is the screenshot taken after executing and stopping:

I tested with clean and fresh SDK but the error persists. Is this correct to generate the zip file for the application:

C:\Program Files\Nordic Semiconductor\Master Control Panel\3.10.0.14\nrf>nrfutil .exe dfu genpkg --application E:\nRF51_SDK_9.0.0_2e23562\examples\ble_peripheral \ble_app_hrs\pca10028\s110_with_dfu\arm5_no_packs_build\nrf51422_xxac_s110.hex --application-version 0xffffffff --dev-type 0xffff --dev-revision 0xffff --sd-re q 0x64 E:\nRF51_SDK_9.0.0_2e23562\test.zip Zip created at E:\nRF51_SDK_9.0.0_2e23562\test.zip

Am I doing mistake in generating the zip file?
