CC2652RB: Max advertising interval

Part Number: CC2652RB
Other Parts Discussed in Thread: SYSCONFIG, CC2640

I want to implement the lowest power advertising interval that will still play nice with connecting to the TI Starter app. I see the CC2640 has an interval from 20ms to 10.24s. The Core v5.2 docs state that this is up to 10,485s, and SysConfig shows up to 480000ms. Which is correct?

Basically, spec mention interval can be in the range of 20 ms to 10,485.759375 s so any implementation in this range should be fine. You see CC2640 has an interval from 20ms to 10.24s and SysConfig shows up to 480000ms, both are no problem.

YiKai, I'm just asking about the CC2652. SysConfig says 20ms to 480000ms for my project, why is that different from the BTE documentation?

Isn’t 480000ms less than 10, 485.759375 s? I see no problem on this since it is in the range of spec.

The spec says 10485.759375s but inside SysConfig it says 480000ms.

Hi,

It may have been an oversight; I don't see this in the SDK4.40 that uses Sysconfig 1.7.0.

Regards,

Rafael

Interesting. I just upgraded the SDK and Sysconfig and my hints are still the same. I don't think I need longer than 480s, I just want to know if TI is imposing their own spec there.
