Power profiling of nRF7002 DK

You can use the Power Profiler Kit II (PPK2) with the nRF7002 DK to evaluate the power consumption of nRF70 Series devices in Low-power mode. To measure the power consumption of the nRF7002 DK, complete the following steps:

  1. Remove the jumper on P23 (VBAT jumper).

  2. Connect GND on the PPK2 kit to any GND on the nRF7002 DK. You can use the P21 pin 1 labeled as GND (-).

  3. Connect the Vout on the PPK2 kit to the P23 pin 1 on the nRF7002 DK.

    To reproduce the plots for DTIM period of 3, complete the following steps using the Wi-Fi: Shell sample:

    1. Configure an AP with DTIM value of 3.

    2. Connect to the AP using the following Wi-Fi® shell commands:

      wifi scan
wifi connect -s <SSID> -k <key_management> -p <passphrase>

    3. Check the connection status using the following Wi-Fi shell command:

      wifi status

    To reproduce the plots for TWT interval of one minute, complete the following steps using the Wi-Fi: Shell sample:

    1. Connect to a TWT supported Wi-Fi 6 AP using the following Wi-Fi shell commands:

      wifi scan
wifi connect -s <SSID> -k <key_management> -p <passphrase>

    2. Check the connection status using the following Wi-Fi shell command:

    3. Start a TWT session using the following Wi-Fi shell command:

      wifi twt setup 0 0 1 1 0 1 1 1 8 60000
