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:

No, I was compiling the project located in \nRF51_SDK_9.0.0_2e23562\examples\ble_peripheral\ble_app_hrs\pca10028\s110_with_dfu\arm5_no_packs.

Now I tested with the file mentioned by you and yes I am not getting any errors and firmware upgrading. What is the difference between these two files? As suggested in nordic document, we have to use hrs_with_dfu, Right?
