Still happening in v3.3 it'd seem v3.3-127-g0a0f2caa1

I (372) espnow_example: WiFi started
ESP_ERROR_CHECK failed: esp_err_t 0x3002 (ESP_ERR_WIFI_NOT_STARTED) at 0x400876c4

tried down to v3.1. Tried adding a delay in between esp_wifi_start() and the set_channel() function but no change. Issue with set_channel()? How do you set the channel otherwise to enable discovery?

@alexanderturner this is NOT bug, in the latest v3.3, we added the limitation to esp_wifi_set_channel(), it can be called only both of following conditions are met:

esp_wifi_start() is returned
sniffer is enabled

alexanderturner · 2019-11-12T03:51:18Z

Thanks @liuzfesp!

The issue is that the example crashes during runtime; the example provided in ESP-IDF. The issue is to correct the example.

There's a bit of a lack of documentation/example with ESP-NOW, does it require the wifi to be in promiscuous mode? If it does; can the radio also act as SoftAP?

Alex

alexanderturner · 2019-11-14T02:44:24Z

Really need some help with this one - any follow up from Espressif?

negativekelvin · 2019-11-14T03:04:52Z

this is NOT bug, in the latest v3.3, we added the limitation to esp_wifi_set_channel(), it can be called only both of following conditions are met:

esp_wifi_start() is returned

sniffer is enabled

Should always work unless STA mode is connected to an AP or a scan is in progress. Required for espnow and esp_wifi_80211_tx.

#4005

alexanderturner · 2019-11-16T11:43:06Z

Thanks @negativekelvin any chance you can try run the example and see what's happening. I've tried to get espnow running a few times now and I'm not having any luck at all - I'd love to avoid spinning up a BLE stack if possible

espressif/esp-idf#4005

alexanderturner · 2019-11-21T07:52:04Z

Anything here guys? @negativekelvin @liuzfesp

negativekelvin · 2019-11-21T08:06:57Z

For now, fix is to just not set the channel b9da410#diff-71d4a3ad5cf2dcb1e3f6bd8eff374134

But hopefully it will be fixed later so that user can set any channel

alexanderturner · 2019-11-21T08:31:26Z

@negativekelvin I'm trying to use this to discover ESP32's, is it possible to discover them without setting the channel?

negativekelvin · 2019-11-21T09:08:30Z

If they all stay on default channel

alexanderturner · 2019-11-21T09:11:46Z

Thanks - not sure if I can guarantee that. Looking to discover ESP's then have them join the 'master's' AP which may be on a different channel. Makes it hard to guarantee that they'll stay on the same channel.

Is there another way to change the channel? Even if I bounce it into another mode - this is very valuable to me as it prevents me from enabling the BLE stack

zhangyanjiaoesp · 2019-11-21T11:20:19Z

@alexanderturner

I'm trying to use this to discover ESP32's

I'm sorry I can't understand you. Do you mean you want to discover an ESP32 with ESP-NOW ?

alexanderturner · 2019-11-21T11:21:33Z

Hi @zhangyanjiaoesp that's right. In a network of ESP32's, I want a "master" to be able to discover a "slave" so it can adopt it.

zhangyanjiaoesp · 2019-11-21T11:43:32Z

@alexanderturner
You mean your "slaves" (or "master")have connected with other APs, and they are in different channels, you want to use 'esp_wifi_set_channel()' to change the channel of the "master" (or "slave") , then "master" can discover them, is that right?

alexanderturner · 2019-11-21T14:00:29Z

Correct @zhangyanjiaoesp

zhangyanjiaoesp · 2019-11-22T02:23:20Z

@alexanderturner
Currently, you can only call esp_wifi_set_channel() after wifi initialized and sniffer enabled. We are trying to modify this function to let it can set the channel as long as the wifi initialized, thus you can set the channel in STA mode. But we will still don't support setting channel when the STA has connected to an AP, or when STA is scanning, or STA is connecting to an AP.

lgnativs · 2019-11-30T02:23:07Z

@zhangyanjiaoesp ,我碰到了同样的情况
代码如下:

 if(!radio_inited) {
        esp_initialize();
        if(!wifi_started) {
            ESP_LOGE("radio", "init and start wifi");
            wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
            ESP_ERROR_CHECK(esp_wifi_init(&cfg));
            ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_RAM));
            ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
            ESP_ERROR_CHECK(esp_wifi_start());
            wifi_started = true;
            ESP_LOGE("radio", "wifi started!");
        }
        ESP_LOGE("radio", "wifi status = %d", wifi_started);
        ESP_ERROR_CHECK(esp_wifi_set_channel(radio_channel, 0));

错误信息:

同样的代码用IDF 3.3的版本是没问题的,但是现在的4.0的就报错,这个功能对我的项目很重要,设定channel功能也是必要的.

请问什么时候能修复这个问题呢?

zhangyanjiaoesp · 2019-12-02T02:25:32Z

I think it will be merged into IDF this month.

justoke · 2019-12-27T21:48:37Z

I have the same error/issue using the ESP32 on PlatformIO under the Arduino framework.

 tcpip_adapter_init();
      wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
      ESP_ERROR_CHECK(esp_wifi_init(&cfg));
      ESP_ERROR_CHECK(esp_wifi_set_country(&wifi_country));
      ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_RAM));
      ESP_ERROR_CHECK(esp_wifi_set_mode(ESPNOW_WIFI_MODE));
      ESP_ERROR_CHECK(esp_wifi_start());
      ESP_ERROR_CHECK(esp_wifi_set_channel(_channel, WIFI_SECOND_CHAN_NONE));

      // Initialize ESPNOW and register sending & receiving callback function
      ESP_ERROR_CHECK(esp_now_init());
      ESP_ERROR_CHECK(esp_now_register_send_cb(espnow_send_cb));
      ESP_ERROR_CHECK(esp_now_register_recv_cb(espnow_recv_cb));

      // Set primary master key
      ESP_ERROR_CHECK(esp_now_set_pmk(_esp_pmk));

Run-time error occurs on this line:
ESP_ERROR_CHECK(esp_wifi_set_channel(_channel, WIFI_SECOND_CHAN_NONE));

What needs to be done to make sure the conditions are met please? This is code that used to work.

justoke · 2019-12-28T11:49:03Z

@alexanderturner I'm not sure exactly where you should change the code in your example, but I had to do this to get it to work as per the documentation. Without esp_wifi_start and esp_wifi_set_promiscuous the channel set method would always fail with the run-time error you described.

    //These two steps are required BEFORE the channel can be set
    // As per the documentation from Espressif:
    // https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/network/esp_wifi.html#_CPPv420esp_wifi_set_channel7uint8_t18wifi_second_chan_t
    ESP_ERROR_CHECK(esp_wifi_start());
    ESP_ERROR_CHECK(esp_wifi_set_promiscuous(true));

    ESP_ERROR_CHECK(esp_wifi_set_channel(_channel, WIFI_SECOND_CHAN_NONE));

Fix following WiFi issues: 1. Fix WiFi buffer reload issue 2. Fix AMSDU decrypt issue 3. Fix some WiFi timer issues 4. Fix the crash caused by too big of association request RSN information 5. Fix the crash caused by block scan 6. Fix the bug for getting channel and bandwidth 7. Fix some Sniffer bugs 8. Fix some ESP-NOW issues 1> fix the bug when modifying the channel info of peer node 2> fix the crash when modifying peer node between unencrypted and encrypted 3> fix the bug for fetch peer 4> modify the esp_wifi_set_channel() function 5> fix the bug that the channel parameter doesn't work when adding peer node Closes #2833 Closes #4311
