I set advertisement interval below using Wiced Smart SDK running BCM92073X_LE_KIT.
/*.high_undirect_adv_interval =*/ 800, // 32 slots (20ms)
and other setting is
/*.high_undirect_adv_interval =*/ 1600, // 32 slots (20ms)
But we found there is no difference between 800 slots and 1600 slots on power consumption.
Power consumption is the same between 800 slots and 1600 slots.
My test is correct?
I ran hello_sensor application. I just modified adv_interval.
I'm looking forward to BRCM experts' reply.
Solved! Go to Solution.

First of all, the tag3 is not the best platform to measure current consumption.
800 slots (0.5s) is a rather long interval for high_undirected as compared to the hello_sensor. Assuming you are in sleep mode after each advertising event and you set a long enough duration, I will not be surprised if you get 22uA, considering the sleep current for the 20737 (chip only) is around 12uA.

Not sure how you measure the power consumption on your tag3, but below is a good write-up by JT on this topic.
So what kind of readings did you get?

The current value of interval 800 slots and 1600 slots is 0.022 ma.
Is it correct value?
Thanks in advance.
