Prototype current consumption high

[annapalu]

Hi all, i development a FW with a low power and when i measure the power consumption using a nrf connector on evaluation board i have 2 ua, and it's ok. Now i have the some hw, on my prototype when i use a nrf52 and the consumption is very high 400 ua. I use an amperometer serial with a power supply to measure the current consumaption.

Somebody have an idea abou the reason?

Thanks, Anna

This is my configuration:

   nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC;

   // Initialize the SoftDevice handler module.
   SOFTDEVICE_HANDLER_INIT(&clock_lf_cfg, NULL);


// Low frequency clock source to be used by the SoftDevice
#define NRF_CLOCK_LFCLKSRC      {.source        = NRF_CLOCK_LF_SRC_XTAL,            \
                                 .rc_ctiv       = 0,                                \
                                 .rc_temp_ctiv  = 0,                                \
                                 .xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}
