Hi, 

I have  CC2510DK-MINI. During the test mode PM2 and PM3 I see that modules consume  ~24 uA.

I read your appnotes about power saving.  Also I used your example. 


Why modules consume so much? 

CC2510 PM3

    I checked Pull-Up resistor.  In both modules Pull-Up res on P0_2 pin = 3.61-9 M.  Is this normal??  Or, I bought a faulty modules in estore.ti ?

    Hi Andrey,

    According to CC2510 datasheet, the internal pull-up/down typical resistors' value should be 20KOhm.

    So, there are 3 options:

    • It may be a faulty module.
    • Something connected to this pin, and the resistance is much higher.
      Or it may be so that those pins are configured to act as tristate. 
    • Your measurement is somewhat wrong.

    Br,

    Igor

    With these modules, something is wrong. Pull-Up/ Pull-Down res on P0.2 not work.
