Hi again,

Could you give some more detail on how long it takes ? When you integrate MCUBoot , it will boot first and may do some verification but it shouldn't take a significant time (few hundred ms).Have you checked the log to see at which step it spend it time. You should be able to see the MCUboot log.

If you have done a DFU , then MCUboot will have to swap the image and the process may take time depends on the size of the image (can be 30 40 seconds)

Have you tried to test with smp_svr to see if the example have the same problem ?

Many Thanks for your reply. I managed to get it working however, it is taking a very long time to start after system reset. Is there a way to fix this ?

My current proj.conf file is as follows:

Hi Christopher,

Please follow our guide here on how to integrate the SMP service in your application.
Basically you need to enable the CONFIG_s and then call smp_bt_register() to register the service.
