CC1350STK: Simplelink wake-on VS BLE in power consumption

Part Number: CC1350STK
Other Parts Discussed in Thread: CC1350

Hi, I have some trouble in measuring the power consumption of CC1350STK(but I will manage to use a DC power analyzer later)

Have u roughly measured the power consumption of RF wake-on( with default parameters)? I want to compare its power consumption with that in BLE to see which is more energy-saving

Thank you in advance

    Hi Jason, what do you mean by RF wake-on? Do you mean what the consumption is for transmitting a packet? If so I can provide some measurement data for you based on the rfPacketTx example with default Tx power (12.5 dBm), where the device goes from standby to active Tx back to standby...

    I am sorry I didnn't express my question very clearly... In Wor, when the device acts as a RF packet receiver(RX), it checks RF signals in the air from time to time. I want to know the power consumption when the device keeps checking RF signal in the air

    Hi Jason - ok.

    So I did a couple of measurements for you for the rfWakeOnRadioRx example (as is without modifications) for supply voltage VDDS = 3.3V.

    The first one is for the  CC1350 Launchpad.

    I chose to measure this first as these numbers will be close to the performance of the CC1350

    The average current consumption is 33uA:

    Then I measured the CC1350STK. The example as is will lit a LED, so the current consumption will be higher.

    Here I measure 3.4 mA:

    If you modify this example by turning off the LED and other peripherals you should see the same numbers as I got with the Launchpad.
