PAN9520 Wi-Fi Module
Editing "Phy Init Data" in the Source Code
6.1.2.2
Per default, the "phy init data" set defined in the source code is used by the PAN9520.
Therefore, adapting this data is also an option to comply with the regulations. The data can be
found in [ESP-IDF] > components > esp_wifi > esp32s2 > include >
phy_init_data.h.
The structure phy_init_data of type phy_init_data_t contains the configuration bytes.
These are the same as described in
bytes and end bytes are missing. Therefore, the byte enumeration is decreased by eight.
The code examples for RED (EU) and FCC/IC (USA and Canada) are described below.
