Re: WiFi Alliance Certification

Current WFA certification BIN doesn't support pin remapping, suggest to get support from sales@espressif.com.

Re: WiFi Alliance Certification

HI ctmurp,

RF performance tester application can't be used for WFA certification testing. Currently we haven't made WFA certification BIN public, you can send mail to sales@espressif.com to get the WFA certification BIN.

Re: ESP32 连接WIFI路由器时UDP通信异常 [WIFI-1710]

Hi zhoujh,

如果使用电脑通过 WiFi 连光猫做类似的操作,是否能正常通信?

Re: 碰到wifi: ap_probe_send over, resett wifi status to disassoc问题

Hi Jimmy,

你提到的内存泄漏是指应用层还是 IDF 存在内存泄漏?为什么怀疑是内存泄漏导致?

Re: APSTA Mode - STA connected but not accessible after random period of time

Hi @awander, @teckhaokoh,
  • Is the problem easy or hard to be reproduced? About how long time for you to reproduce the issue?
  • How about configured the Router to open mode (Disable encryption mode)?
  • Does the issue still exist if change the Router to hotspot of phone?

Re: Does station<->station communication get forwarded over the AP? [WIFI-2280]

Hi,

Could you explain "the esp_wifi_80211_tx API isn't triggering the CSI callback" in detailed? Could you help to provide following info:

1. How to use esp_wifi_80211_tx
2. How to encapsulate the WiFi raw packets
3. The mac address of all your STA/AP

Then we can check what's wrong in your code.

Re: ESP32可以指定BSSID和密码来连接WIFI吗?

Hi,

IDF 不支持直接使用 bssid 连 AP,应用可通过下面的方式实现类似的功能:
1。 先调 scan
2。 从 scan 的结果通过 bssid 找到要连的 ap 的 ssid
3。 同时设置 ssid/bssid 去连 AP。

Re: Does station<->station communication get forwarded over the AP? [WIFI-2280]

Hi @ Dumbledore, `Therefore the only way to get CSI from all channels between more than two boards is Station<->Station communication - and it seems like this won't work, too, since I'm always only really measuring the channels from AP to the others because of AP forwarding.` How about using ESP32 S...

Re: 碰到wifi: ap_probe_send over, resett wifi status to disassoc问题

Hi,

如果连同一个 AP,有一个有问题,另一个没有问题,而且重起 AP 无法恢复,可能是 WiFi RX 挂了,导致收不到 beacon。这个问题应该在 v3.2 中 IDF commit: 3750fe94 中 fix 掉了。

Re: Does station<->station communication get forwarded over the AP? [WIFI-2280]

Hi Dumbledore,

Yes, station <-> station communication depends on AP forwarding. If we disable AP forwarding, station <-> station communication is broken, I'm not sure this is what you expected.

Moreover, currently we have no API to disable AP forwarding.
