can the nrf52 read the temperature data when it is sleep mode?

Hi,

i have a custom board with nRF52832 and temperature sensor in it.

my question is whether i can read the temperature from sensor via I2c when the device is in sleep mode.

If you are using EasyDMA and the pointers are already configured before the MCU goes into sleep, then the data transaction can be triggered with MCU still in sleep. The MCU needs to wakeup once the sensor data is transferred to RAM so that it can process that info.
