Other Parts Discussed in Thread: CC3200

Hi,

The file "CC3200 Current Measurements" in wiki showcases that the chip takes 120uA in LPDS mode, with idle_profile.

But I do the experiment with this example codes and I find the current is almost 1mA, far higher than data of the file.

I use LP with XCC3200HZ.

I modify the second parament ( sl_WlanPolicySet(SL_POLICY_PM, SL_NORMAL_POLICY, NULL, 0)) to SL_LOW_POWER_POLICY, and the result is the same.

Need I modify other codes in this example so that cc3200 can take 120uA?

Hi,

How are you testing the current on board? Which pins you are using?

I remove the J12,and link the two pins of J12 to the equitment.

Are you measuring the average current as 1mA?
What is the floor current you are seeing?

Please refer to section 4.9 of the CC3200 datasheet for the revised current numbers.

After days of test, I can not yet reach the aim that it takes 120uA in LDPS.
But thanks for your reply.
Best wishes.
