ESP32-S3 Emission Test - Set WiFi to RX Mode

Postby slazyhw » Mon Jul 06, 2026 11:12 am

Hi, in context of a planned emission test, I need to set the WiFi module of my esp32-s3 into RX mode. Is there a specified way to achieve this operation mode? I stumbled across

Code: Select all

esp_wifi_set_promiscuous
but I am not really sure if that is the right approach. The RF module just needs to be active without actively transmitting.

ESP-NOW maybe.
