Configuring WiFi Channel Bandwidth in Arduino

Postby noamaiz » Thu May 26, 2022 5:01 pm

I know that with esp-idf you can change the bandwidth (20 or 40MHz) in the config. Is there any way to currently do this in Arduino IDE? I want to be able to set bandwidth to 40MHz for FTM.

The Arduino IDE is built on top of ESP-IDF; as long as what you want isn't decided compile-time, you should be able to use the ESP-IDF functions after including the proper headers.

Hi, I have the same problem: there is no way to specify a 40MHz BW in FTM initiation. Because FTM works in unassociated state, the esp_wifi_set_bandwidth API does not work.
