TuyaOS Wi-Fi (tal_wifi)

Demos: software/TuyaOS/apps/tuyaos_demo_examples/src/examples/os_wifi/

Also related (product remote, not basic STA/AP):

Confirm first

• Role: STA / AP / scan / LP / FFC remote?
• STA: SSID + password (never hardcode secrets from demos — demos use placeholders).
• AP: SSID, password, channel, IP/mask/gw if static.
• Whether the app already runs a higher-level TuyaOS product init (example_soc_* / framework Wi-Fi). If the product stack owns Wi-Fi, do not double-tal_wifi_init without checking existing code.

Core APIs

STA pattern (adapt demo — do not leave xxxx credentials)

#include "tuya_cloud_types.h"
#include "tal_log.h"
#include "tal_wifi.h"
 
static void wifi_event_callback(WF_EVENT_E event, void *arg)
{
    (void)arg;
    switch (event) {
    case WFE_CONNECTED: {
        NW_IP_S sta_info;
        memset(&sta_info, 0, sizeof(sta_info));
        if (tal_wifi_get_ip(WF_STATION, &sta_info) == OPRT_OK) {
            /* log ip/gw/mask — field names differ by SDK macro (nwipstr vs .ip) */
            TAL_PR_NOTICE("wifi connected");
        }
        break;
    }
    case WFE_CONNECT_FAILED:
        TAL_PR_ERR("wifi connect failed");
        break;
    case WFE_DISCONNECTED:
        TAL_PR_NOTICE("wifi disconnected");
        break;
    default:
        break;
    }
}
 
void app_wifi_sta_start(const char *ssid, const char *passwd)
{
    if (tal_wifi_init(wifi_event_callback) != OPRT_OK) {
        TAL_PR_ERR("tal_wifi_init failed");
        return;
    }
    if (tal_wifi_set_work_mode(WWM_STATION) != OPRT_OK) {
        TAL_PR_ERR("set station mode failed");
        return;
    }
    tal_wifi_station_connect((SCHAR_T *)ssid, (SCHAR_T *)passwd);
}

SoftAP (summary)

From example_os_wifi_ap.c:

1. tal_wifi_init(cb)
2. set AP work mode
3. fill NW_IP_S (ip/mask/gw) + SSID/password/channel
4. tal_wifi_ap_start(...) (exact prototype in demo / tal_wifi.h)
5. optional: tal_net_socket_create + tal_net_send_to for LAN broadcast

Scan (summary)

tal_wifi_all_ap_scan(&ap_list, &count) then print SSID/RSSI/auth; always tal_wifi_release_ap(ap_list) when done.

Low power (summary)

After STA is up: tal_wifi_set_lps_dtim(...), tal_wifi_lp_enable(), and platform CPU LP helpers (tal_cpu_set_lp_mode / tal_sleep) as in the LP demo. Disable LP before heavy traffic.

Rules

1. Open the matching demo `.c` in-tree when present; copy event handling and struct field names for this SDK version.
2. Never commit real passwords from chat into source without user OK; use config / macros the app already uses.
3. Product vs raw Wi-Fi: many commercial apps already init Wi-Fi inside TuyaOS product/device init. Grep the app for tal_wifi_init / tuya_iot_* first.
4. FFC remotes use tuya_iot_wifi_ffc_init/control/bind/send — different stack; read service_ffc_* READMEs.
5. Build with `tuyaos-build`. Not TuyaOpen tos.py / lwIP-only examples from other trees.
