Detailed Documentation of "WIFI_BAND_MODE_AUTO"

Postby Weigen Qiu » Fri Jun 06, 2025 10:25 pm

for the dual band ESP32C5, what is the result of calling the API esp_wifi_set_band_mode(WIFI_BAND_MODE_AUTO)?
Can I create two APs or two STAs, one with 2.4GHz, and the other on 5GHz, or in case of APSTA mode, AP on 5GHz, and STA on 2.4GHz, or vice versa? I couldn't find any documentation on this.

@nopnop2002
did you manage to figure out where we can use different frequency bands simultaneously for SoftAP and STA mode? We actually want to connect our ESP32 chip to a 5GHz network and than want it to act as an AP and broadcast at 2.4GHz for our other ESP32 old chip to connect.
Any help would be highly appreaciated!

I don't have esp32-C5 development board.
