Hello,

I suggest that you use the DFU request to set a flag. This way, you can check this flag in the main thread, to see whether it has been requested. If it has, then you can shut down the TWI gracefully before doing the DFU reset.

Short, but hopefully explaining pseudo code:

DFU_interrupt(void)
{
    DFU_reset_requested = true;
}

main()
{
    ...
    while(1)
    {
        ...
        if(DFU_reset_requested)
        {
            prepare_DFU();
            reset();
        }
        idle_state_handle(); //or whatever the wait function is called in the project
    }
}

Best regards,

Edvin
