[solved] Get RSSI passively using NimBLE (not active probe or connection)

I am trying to continuously scan around for BLE beacons using NimBLE stack on ESP32-pico on ESP-IDF 4.4. Is there any way to get the MAC and RSSI of beacons without doing an extended, active-probe, or connection/discovery? I just want to passively collect the data as fast as possible in a 1-sec scan...

BLE -- Automatic Light Sleep support (Nimble vs Bluedroid)

Hi which BLE stack has the lowest power? Bluedroid or Nimble?
Do either of these support automatic light sleep?

Thanks

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...
