Hi Dilip,

The current consumption for a normal mesh node (not the low power node) should be almost the same as the RX current of the radio. The reason is that the Radio has to stay in RX all of the time to scan for any packet. And this will be the significant current draw of the device. The CPU may be active when there is a packet to process but that's wouldn't contribute much to the average of the current consumption in the long run, unless you send and receive data at a very high rate.

You can find the RX current in the product spec. Or you can have a look at the online power profiler here: https://devzone.nordicsemi.com/nordic/power/
