Re: Mesh uses HT40, this uses too many channels. Can I used HT20?

got it to work, doing the following:

Code: Select all

        ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_APSTA));
        ESP_ERROR_CHECK(esp_wifi_set_bandwidth(ESP_IF_WIFI_STA, WIFI_BW_HT20));
        ESP_ERROR_CHECK(esp_wifi_set_bandwidth(ESP_IF_WIFI_AP, WIFI_BW_HT20));

Re: Mesh uses HT40, this uses too many channels. Can I used HT20?

tried both modes, and it did not work.... was this ever tested?

Code: Select all

esp_wifi_set_mode(WIFI_MODE_APSTA);
esp_wifi_set_bandwidth(ESP_IF_WIFI_AP, WIFI_BW_HT20);


esp_wifi_set_mode(WIFI_MODE_STA);
esp_wifi_set_bandwidth(ESP_IF_WIFI_AP, WIFI_BW_HT20);

Mesh uses HT40, this uses too many channels. Can I used HT20?

Mesh uses HT40, this uses too many channels, causing issues with existing Wifi infrastructure in large buildings.
Is it possible to force everything to go down to HT20, so less 2.4GHz channels are used?

Thanks :D

Re: "wireless debug" -- how I think it works -- wifi congestion, limitations

That makes sense.
Sometimes I do that that the sniffer can no longer send commands to the nodes. Anything that can to periodically reset the espnow on the node, to ensure that it is always working?

"wireless debug" -- how I think it works -- wifi congestion, limitations

Hi, I am using mdebug_esp, "wireless debug". This is an amazing & powerful tool! I want to use it correctly, and not have my mesh nodes doing extra transmissions. Here is my understanding, can anyone please confirm: Step 1. I power on Mesh; (running on channel x). Every node in mesh will listen to E...

mesh "wireless debug" (esp now) -- do i need to be connected to wifi router?

Question on mesh "wireless debug" (esp now) -- do i need to be connected to wifi router?
If my mesh spans far from wifi router, can I still sniff packets when I take my wrover-sniffer board far away from router, and close to the edge of the mesh?

I am seeing failures at the edge of the mesh.

yes, we are using ESP-NOW for debuging, please refer to this demo : https://github.com/espressif/esp-mdf/tr ... less_debug
wow, just in time :o

Re: Possible for intermediate parent to connect with WiFi as well?

ESP_LBB
Looking for a method to debug complex mesh issues, and corner cases like crashes.
Another thought I had was running BLE (gatt-server) on all of them, and viewing logs that way. or maybe ESPNOW?

Thanks! :D
