Current consumption at startup 2

Hi support team!

It is a related question of "Current consumption at startup" that I posted last week.
I checked the operation with reference to the information you have already sent.
By setting the default STARTUP_SLEEP_DELAY_DEFAULT setting value to less than 2 seconds,
it is now possible to sleep more quickly.
However, when I set a value of about 1 second or less,
there is still time to sleep for about 1 second regardless of the setting value.
What kind of cause do you think is?

Since we do NOT plan to use XTAL 32k, CFG_LP_CLK LP_CLK_RCX20 is defined in da 1458x_config_advanced.h.

regards,

Jun-ichi

Hi Jun-ichi Tobe,

Hi Jun-ichi Tobe,

The 585 uses a different stack than the 580 and supports new features (like the Secure Connections), the delay that you mention comes from the rwip_schedule(), which is a ROM function, and this delay in sleeping is due to the key generation of the feature mentioned above, you will not be able to ommit that. Is there any specific reason for wanting to reduce that always on state ? Does this delay in sleeping induces any issues to your device ? Since this extra power consumption occurs only during boot up.

Thanks MT_Dialog

Hi MT_Dialog!

Hi MT_Dialog!
Thank you very much for your support.

I comment as follows.
I use a rechargeable battery with a very small capacity.
Therefore, it can not consume current for a long time.
Considering the characteristics of the battery, we are examining how short it should be to the present.
I would like to prioritize the current consumption rather than the new function,
so it would be great to teach me how to disable the use of each new function.

regards,

Jun-ichi

Hi Jun-ichi Tobe,

Hi Jun-ichi Tobe,

Well, i dont think that there is a way to disable that, as mentioned this is a ROM function and you cannot just disable it. So, you are just trying to minimize the power consumption of the device, not because the extra power draw when bootup causes you any issues ? Do you expect a number of boot ups during the lifetime of the product ? Since as mentioned this will occur just once during booting up.

Thanks MT_dialog
