Re: WiFi transfer speed starts out great, then crashes down: can the ESP32's WiFi dynamic rate scaling algorithm be tune

esp_wifi_internal_set_fix_rate is a internal debug API. Use esp_err_t esp_wifi_config_11b_rate(wifi_interface_t ifx, bool disable); will be easier. Well, It is hard to say the reason. But I can try to explain it. The dynamic rate scaling of ESP32 is based on the PER(packet error ratio) and RSSI. The...

Re: ESP RF Test Tool not compatible with native USB on ESP32-S3

Sorry for the delay. Using USB to download and run RF test firmware is not tested internally. The issues I can image: 1. USB may use bigger memory block in the ROM, which may cause corrupted when downloading through USB. 2. USB PHY in ESP32S3 impacts the RF performance somehow, it is possible that t...

Re: 802.11 QoS Frame Ack Policy

ESP32 doesn't send QoS No Ack packets, but you can try to send broadcast/multicast packets(which also sent by VO queue) instead to verify at the moment.

Re: esp32 softap模式兼容性问题

这个问题比较奇怪,可以做以下排查
1. 是否使用SPIRAM?是否使用双核?
2. 最好有稳定复现的小代码,如果没有,可以先提供 bin 文件和 log,进行排查。
3. 提供出问题的设备型号。
4. 实在没有办法就只能现场排查了。

Re: WIFI Direct support for ESP32 in esp-idf

esp-idf do not support WiFi Direct. But why the ESP32 data sheet include this, that's because WiFi Direct is a 90%(not accurate) software feature. As a chip, ESP32 can support WiFi Direct, and in fact, it support WiFi Direct in some hosted system(host system support WiFi Direct stack). WiFi Direct i...

Re: ESP32 not adhering to negotiated 802.11 data rates

Sorry, ESP32 have some limit here. I think most Apps can not disable b rates. For some APs, if you do not support 1Mbps or 2Mbps, it is impossible to connect to them. But we will fix this on some version, maybe idf4.0.

If you really need P2P, you can go business way.

Re: Whether the wifi-lib contains wifi-p2p mode?

Sorry, currently, P2P is not in our schedule in IDF. The priority of P2P is low now.

Re: Testing with Anritsu MT8860C

Yes, this is a known issue. By now, ESP32 only support switch among 11b / 11g / 11n.
However, we have the binary to test TX.
