ESP-IDF v5.0 - Disable CCA Can't Receive Packet

[JACKTW]

Hi Sir:

I use esp_wifi_80211_tx()/esp_wifi_set_promiscuous(true) to transceive the 802.11 data frame on ESP32-WROVE-E module, but the packet latency is almost 10ms due to CSMA/CA.

After disabling CSMA/CA by esp_rom_phy_disable_cca(), I found latency will keeping around 250 ~ 350us, but I can't receive any packet at all.

How can I keep the transceived functionality and short latency in same time !

Best Regards,
Jack
