LP-EM-CC2340R5: RPA Update Interval

Prince John

Part Number: LP-EM-CC2340R5

Hi All,

What is the maximum time, which we can set for RPA update interval ?

From the gap.h file maximum value we can set for GAP_PARAM_CONN_PARAM_TIMEOUT is 65535. 
i.e., 65535 minutes = 1092.25Hrs = 45.51 Days.

Is it possible to configure 45 days for RPA update interval ?
Is my understanding is right ? 

Regards,
Prince

    Prince, 

    As you stated, it is possible to configure the RPA update interval to its maximum value of 65535, which is in minutes so your calculation is correct. However, the parameter which you would want to change would be the GAP_PARAM_PRIVATE_ADDR_INT, not the GAP_PARAM_CONN_PARAM_TIMEOUT if you are wanting to update the address after a default timeout interval. 

    I would recommend reading through the Privacy section of our User's Guide (more specifically the Host Responsibilities subsection) for more info on Setting Privacy-related GAP Parameters including the Resolvable Private Address Timeout. 

    Thanks,

    Luke

    Hi Luke,

    Apologies for confusion. You are right. It is GAP_PARAM_PRIVATE_ADDR_INT.

    The document only talking about default time 15 minutes. We would like to know about the maximum limit which we can set.

    Prince, 

    No worries at all, I am glad I could help clear up any confusion! Yes, the document states the default time of 15 minutes but if you click on the link in that same section for GAP_PARAM_PRIVATE_ADDR_INT, it will take you to a table listing the same default value of 15 minutes as well as its range of values with the maximum being shown as 65535. 

    Hope this further clarifies on the answer to your question.

    Thanks,

    Luke

    Hi Luke,

    Thanks for clarifying. 

    This means we can configure RPA update time up to 45 days.
