DFU support in Fast pair locator tag on nRF52833-DK

[Jignesh shingala]

Hi every one,

If any body have been succeeded  in adding DFU support in Fast pair locator tag on nRF52833-DK, if so can you guide me for it?

I am getting configuration and partition manager error every time.

regards,

Jignesh

Hi,

DFU should be enabled by default if you select the "release" configuration. Did you try that? 

Best regards,

Vidar

Hi Vidar,

With this change it build successful, but when i tried to do dfu with generated dfu_application.zip, it is failing in eneabling bootloader. I have tested with DFU and Device manager apps in both app it is failing in bootloader enable.

Also generated merged.hex file siae is 1214KB and dfu_application.zip size is 420KB.

i have build this code for nRF52833-DK, then how merged.hex file size is possible more than 512KB?

Hi Vidar
have you got anything in nrf connect logs?

[Vidar Berg]

again, did you verify whether you were in DFU mode or not?

Hi Vidar,

It is not going in DFU mode, Can you explain me exact key sequence to put this board in DFU mode? 

[Vidar Berg]

Please read the documentation I linked to earlier which also covers how to enter DFU mode, and let me know if there’s anything you find unclear.

Hi Vidar,

Thanks, DFU now working on nRF52833-DK board,

I have one more Query regarding DFU on nRF52832 based custom board for Fast pair locator tag code.

Can DFU enabled same way using release configuration in extra C make arguments or any other configurations required?
