Hi,
I am trying to decrease circuit power consumption that's why I am using sd_ble_gap_tx_power_set(TX_POWER_LEVEL) function. When I set TX_POWER_LEVEL as 4 or -20, I dont see any differences in terms of power consumption. Why is there no difference? Can anyone please help me with this. I am using multimeter to measure the current. I see the following in the spec
You can definitely see a difference if you add a sense resistor to NRF51-DK and look at the voltage across the sense resistor with a differential probe. At 0 dBm:
At +4dBm:
At -8dBm:
A multimeter is most likely just showing you the average background current between advertising events. You might see some difference if you minimize the advertising interval, but a multimeter just isn't a very good way to see these differences.
