What is SYSTEM_EVENT_STA_DISCONNECTED reason code 34
Hi Occaisonally when connecting to WiFi using esp_wifi_connect(), I'm getting the SYSTEM_EVENT_STA_DISCONNECTED event, with a reason code of 34. I can't find reference to it in esp_wifi_types.h or the documentation. Any idea what it might be? Just as an aside, I have lots of problems connecting the ...

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Or should I set the channel to 0? I'm not sure if the AP channel is stored in NVS. I have seen somewhere in the forums that it wasn't.

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Ah, thanks WiFive So if I was to set the wifi_sort_method_t in wifi_sta_config_t to sort on rssi, it'll just connect to the closest AP with the SSID? We store the SSID and passphrase in the NVS, so I assume that if a user was to move the device to another location which was closer to another node, i...

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Does anyone know the answer to this. We’re now having problems with mesh networks. Obviously many APs are being returned in the scan and the ESP doesn’t seem to be able to connect properly to the network.
Thanks
Simon

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
So I have a question which someone from the ESP team should be able to answer (or someone else knowledgable on the subject). In the case where you have an extended network, with two devices with the same SSID on the same channel, if I just connect using SSID and passphrase in the the config struct, ...

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Of course. Thanks. That'll be it! We've had it on a few networks, and I just made the assumption that it was something to do with 5Ghz.
Now I need to work out a way to mitigate that.
Thanks again

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
So I've found some time to do some more research on this. It would seem that some dual-band routers advertise the same SSID on the same channel but with the different BSSID. I'm not an expert on the dual band aspect. But if I do a scan on the ESP, I get: I (2692) wifi: Ap record: ssid: MyAP, bssid: ...

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Hi I am scanning on the ESP32 (returning these results to the app over BLE), and the scan is returning 5Ghz networks that the ESP then fails to connect to. The 5Ghz APs have the same SSID as the 2.4Ghz as well which makes it very confusing. Now that I think of it, it's not consistent across all rout...

Re: Wi-Fi Scanning and excluding 802.11n 5Ghz networks
The problem isn't do with RSSI as such, it's to do with the fact that the ESP doesn't support 5Ghz and therefore these APs should be filtered out of the scan if possible.
Thanks
Simon

Wi-Fi Scanning and excluding 802.11n 5Ghz networks
Hi Our app scans for wi-fi networks to connect to (which a user than then tell the ESP32 to connect to using an app on their phone). When the scan returns, the ap records will contain 802.11n 5Ghz APs that the ESP32 can then not connect to. Is there anyway to exclude or filter out 5GHz APs? I can't ...
