Hi,

Does the nrf_drv_spi_init() return any error code?

Did you follow: http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.2.0/nrf52810_user_guide.html?cp=4_0_0_5_0

Best regards,

Are you using the development kit or your own hardware? What peripherals are on the SPI bus?

You didn't mention which SDK you are using, but I think prior to 14 the drive did enable the pull up on Master In Serial Out (MISO) line which would cause some extra current draw if slave device drives that data line low. In 14 they introduced a define NRF_SPI_DRV_MISO_PULLUP_CFG which if set to 0 doesn't enable the pullup.

But I don't think the pull would be 3mA
