[jtzhang]

Hi all,

 I am confused  about  nrf52832 Tx/Rx max current. I am using PPKII  measure the power current of  NRF52 DK PCA10040 , As the following screen shot,:

In DC/DC mode and Ldo mode , the problem is same , Tx Current burr exceed 10 mA a lot, I have try add cap ,but it didn't work ,How to fix

TX/RX current burr ?

Hi,

Did you try measuring in the Ampere meter mode? Also, did you follow the connection guide?

Best Regards,

Priyanka

Hi Priyanka:

  I know the Ampere meter mode,measure the average current;  The average current is ok, But I  want to know  real TX current , Because I have to choose bigger battery for the higher tx current,The measuring result is different from datasheet a lot. and I cut the jumper  as NRF52 DK guide。
