nRF8001 Current Consumption

[jamilaaria]

Hi,

I have tried changing the connection parameters (min and max connection interval) and looked into nRFGo Studio to see what the current consumption would be. In Column 2, I have the result from the nRFGo Studio. However, when I used it in my board (with microcontroller + nrf8001), I have the current consumption of the nRF8001 in column 3. I was wondering why there is such a big discrepancies in the values.

Connection Interval (ms/ms)	Current Consumption (uA) from nRFGo Studio	Current Consumption (uA) Actual
15/15	657 uA	775 uA
90/105	111 uA	170 uA
150/165	78 uA	114 uA
225/240	60 uA	119 uA
300/315	51 uA	110 uA
375/390	45 uA	120 uA
450/465	40 uA	120 uA

Hoping for your urgent response. Thanks!

Hi Jamila

Have you set the Hardware Settings to the settings you are using? I.E. choosing the correct clock sources, TX power and whether the DC/DC converter is enabled? 

Best regards,

Hi Simonr,

Yes I have set the Hardware Settings in nRFgo similar to what I am actually using, DC/DC enabled etc.

Is the second number in column 1 (I.E. 15, 105, 165 and so on) the advertising interval in nRFGo Studio? Are you using the "Generate source files" option in nRFGo Studio? In that case, please check that your advertising interval is set to the corresponding value in your application as well. Also, how are you measuring the actual current consumption?

Best regards,

Simon
