【已解决】使用esp-now协议时，PHY模式无法设置成WIFI_LR模式

[wuxiansulian]

您好，使用esp-now协议时，无法使用乐鑫专有的远程模式。
串口得到的日志如下所示：
IDF版本 v5.01 芯片 esp32-C3
I (522) wifi:enable tsf
E (522) wifi:failed to post WiFi event=2 ret=259
E (522) wifi:failed to post WiFi event=3 ret=259
I (522) wifi:enable tsf
E (532) wifi:failed to post WiFi event=2 ret=259
W (532) wifi:invalid rate, need change phy mode to LR
代码如下：
wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
ESP_ERROR_CHECK(esp_wifi_init(&cfg));
ESP_ERROR_CHECK(esp_wifi_set_mode(WIFI_MODE_STA));
ESP_ERROR_CHECK(esp_wifi_set_storage(WIFI_STORAGE_RAM)); // WIFI_STORAGE_FLASH WIFI_STORAGE_RAM
ESP_ERROR_CHECK(esp_wifi_set_ps(WIFI_PS_NONE));
ESP_ERROR_CHECK(esp_wifi_set_protocol(ESP_IF_WIFI_STA, WIFI_PROTOCOL_LR));
// esp_wifi_config_80211_tx_rate(ESP_IF_WIFI_STA, WIFI_PHY_RATE_LORA_250K);
或者
// esp_wifi_config_espnow_rate(ESP_IF_WIFI_STA, WIFI_PHY_RATE_LORA_250K);
都测试过，日志是一样的。

有哪位大侠知道是哪里出问题了吗，是esp-now协议本身的问题，还是esp32-c3不支持esp-now速率改变，还是说用法或者函数顺序问题？

[Akintoye]

Did you run esp_netif_init() before any Wifi initialisation?

[wuxiansulian]

After testing, it is true that this function did not initialize. Thank you very much.

[wujing]

我这里一旦调用 esp_wifi_config_espnow_rate(ESPNOW_WIFI_IF, WIFI_PHY_RATE_LORA_500K)就会返回
wifi:invalid rate, need change phy mode to LR，设置成其他速率没有问题，请问你是解决了这个问题吗？
我是在espnow的demo基础上增加了这个速率切换，在esp_wifi_start后调用，但是一直报错不知道什么原因

[wujing]

我在esp32-C3的esp now demo里切换了速率，在
esp_wifi_start后添加了
esp_wifi_config_espnow_rate(ESPNOW_WIFI_IF, WIFI_PHY_RATE_LORA_500K)，如下

Code: Select all

static void example_wifi_init(void)
{
    ESP_ERROR_CHECK(esp_netif_init());
    ESP_ERROR_CHECK(esp_event_loop_create_default());
    wifi_init_config_t cfg = WIFI_INIT_CONFIG_DEFAULT();
    ESP_ERROR_CHECK( esp_wifi_init(&cfg) );
   // esp_wifi_config_80211_tx_rate(ESPNOW_WIFI_MODE,WIFI_PHY_RATE_5M_L);
    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_wifi_config_80211_tx_rate(ESP_IF_WIFI_STA,PreRate);
    esp_wifi_set_bandwidth(ESP_IF_WIFI_STA,WIFI_BW_HT20);
#if 1//CONFIG_ESPNOW_ENABLE_LONG_RANGE
   ESP_ERROR_CHECK( esp_wifi_set_protocol(ESPNOW_WIFI_IF, WIFI_PROTOCOL_11B|WIFI_PROTOCOL_11G|WIFI_PROTOCOL_11N|WIFI_PROTOCOL_LR) );
    //ESP_ERROR_CHECK( esp_wifi_set_protocol(ESPNOW_WIFI_IF, WIFI_PROTOCOL_LR) );
#endif

    //ESP_ERROR_CHECK( esp_wifi_internal_set_fix_rate(ESPNOW_WIFI_IF,true, WIFI_PHY_RATE_LORA_500K));
   ESP_ERROR_CHECK( esp_wifi_config_espnow_rate(ESPNOW_WIFI_IF, WIFI_PHY_RATE_LORA_500K));
    
}

WIFI_PHY_RATE_LORA_500K和WIFI_PHY_RATE_LORA_250K速率不行，其他速率可以
发现会返回错误
W (506) wifi:invalid rate, need change phy mode to LR
不知道是哪里出问题了，按说espnow应该支持LR啊
