Modifying lite mesh ESP_Bridge SSID & pwsd is invalid (AEGHB-591)

[yel-best]

• idf (5.1.3)
• espressif/mesh_lite (0.10.0)

I modified the default MESH wifi SSID & pwd to a custom SSID: ESP_WIFI_MESH & PWD: abcd.123
After I completed the modification and compiled it and wrote it to ESP32S3,
I found that the WIFI MESH in the LOG was still finding ESP_Bridge

I (7261425) [vendor_ie]: esp_mesh_lite_wifi_scan_start return ESP_OK
I (7264253) [vendor_ie]: Mesh-Lite Scan done
I (7264253) [vendor_ie]: Find ESP_Bridge
I (7264254) [vendor_ie]: RTC store: ssid:ESP_Bridge; bssid:74:4d:bd:8a:1b:75 crc:3293051760
I (7264261) [vendor_ie]: wifi_cfg ESP_Bridge router_config mesh-app-iot
I (7264269) [vendor_ie]: esp_mesh_lite_wifi_connect return ESP_OK

mesh-app-iot is my router WIFI, the master node should connect to this routing SSID

what is the problem?

I have enabled the option of WIFI using PSRAM space in the configuration. Is there any impact?

Are there any rules for MESH LITE's SSID &PWD? For example, SSID cannot have special symbols, and PWD can only use letters or numbers?

thanks

can you help me? 🥲

Hi

I will try again. The process and results are as follows. Please give me some help or opinions. Thank you.

I used a simple example, when I ran it for the first time using the default system configuration SSID: ESP_Bridge, PWD: 123456 I found that it can run normally

But when I try to modify the SSID: WIFI-MESH-IOT, PWD:123#123#123 will begin to fail, unable to network normally, and will always be stuck in the LOG.

I (59294) [vendor_ie]: Mesh-Lite Scan done
I (59295) [vendor_ie]: Find ESP_Bridge
I (59296) [vendor_ie]: RTC store: ssid:ESP_Bridge; bssid:68:b6:b3:4f:da:d1 crc:2117311556
I (59303) [vendor_ie]: wifi_cfg ESP_Bridge router_config esq-apps-iot
I (59310) [vendor_ie]: esp_mesh_lite_wifi_connect return ESP_OK

I just modified the parameters in the configuration file: CONFIG_BRIDGE_SOFTAP_SSID & CONFIG_BRIDGE_SOFTAP_PASSWORD

These are the codes of my app_mainfunction

static esp_err_t esp_storage_init(void)
{
    esp_err_t ret = nvs_flash_init();

    if (ret == ESP_ERR_NVS_NO_FREE_PAGES || ret == ESP_ERR_NVS_NEW_VERSION_FOUND)
    {
        // NVS partition was truncated and needs to be erased
        // Retry nvs_flash_init
        ESP_ERROR_CHECK(nvs_flash_erase());
        ret = nvs_flash_init();
    }

    return ret;
}

    esp_bridge_wifi_set_config(WIFI_IF_AP, &wifi_config);
}

May I ask if you modified the CONFIG_BRIDGE_SOFTAP_SSID and CONFIG_BRIDGE_SOFTAP_PASSWORD configuration items? Have these changes been applied to all nodes?
