reduce dfu watch dog timeout in secure bootloader in sdk15.0.0?

[alivexiaoluo]

Hi,

When debugging with sdk_15.0.0 ble_app_butonless_dfu project(application project) + secure bootloader  project(bootloader  project),it will cost about 2~3 minutes for system restart if the dfu fails.If I want to reduce the time consuption when dfu failed,what can i do?

Best regards,

Can you describe what that takes 2-3 minutes? Are you doing a DFU update, which fails, and then it takes 2-3 minutes before the nRF times out? Or is it the application that hangs?

 

BR,

Edvin

Hi,Edvin.

I changed NRF_BL_DFU_INACTIVITY_TIMEOUT_MS = 120000 to NRF_BL_DFU_INACTIVITY_TIMEOUT_MS = 30000 in sdk_config.h in secure bootloader project.System will restart after about 30 seconds when DFU fails.Thank you!
