Hi, Nordic team:
I have migrated application from SDK13.0.0(S132 4.0.3) to SDK15.0.0(S132 6.0.0) on four productions(Prepare for mass production ), but all have the same problem that the power consumption is increased between 600+ uA to 3mA。After careful examination,I think it's related to SPIM driver, the consumption is 600uA+ when invoke nrf_drv_spi_init() and 3.5mA when invoke the nrf_drv_spi_transer() and it's normal after I invoke the nrf_drv_spi_uninit().
note:
1. the device connected to SPI bus is LIS3DH
2. the consumption is normal with SDK13.0.0
3. application code include SPI driver and LIS3DH's driver is not changed
I found that SDK15.0.0 have big change in peripheral driver named nrfx module, can you help me solve the problem ASAP? thanks very much!!!
