Power profiling of nRF7002 DK

The Power Profiler Kit II (PPK2) of Nordic Semiconductor can be used in conjunction 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.

4. Configure PPK2 as a source meter with 3.6 volts.

   To reproduce the plots for DTIM period of 3, complete the following steps using the :ref:`wifi_shell_sample` 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

   The following image shows the PPK2 output for DTIM period of 3:

   To reproduce the plots for TWT interval of one minute, complete the following steps using the :ref:`wifi_shell_sample` 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:

      wifi status

   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
