2.5 Output power configuration
2.5.1 NINA-W10 series
To operate within the regulatory output power limits, the integrator must configure the module as
per the instructions in the following subsections.
The following power configuration for Wi-Fi, Bluetooth BR/EDR and Bluetooth low energy is only valid
for the official v3.1 esp-idf git repository.
2.5.1.1 Wi-Fi output power configuration for version v2.1
The original file (phy_init.c) is located in the folder - ...\esp-idf\components\esp32\ in the official v2.1
esp-idf git repository. Update this file with the values provided below:

{
int8_t *init_data = malloc(sizeof(esp_phy_init_data_t));
memcpy(init_data, &phy_init_data, sizeof(esp_phy_init_data_t));
