Measurements in Modem Sleep modes may increase consumption depending on flash access.
For measurements in Deep Sleep (ULP active) modes, internal peripherals such as GPIO and I2C can continue to operate while the ULP coprocessor is running.

*The current consumption figures for in RX mode are for cases when the peripherals are disabled and the CPU idle.
*The current consumption measurements are taken with a 3.3 V supply at 25 °C of ambient temperature at the RF port. All transmitters’ measurements are based on a 100% duty cycle.
