I try to implement wifi provisioning through BT and the android ESP BLE Prov application.
On the esp side I never get out of the wifi_prov_mgr_wait() function.
On the android app side, on the screen of the phone :
-Sending WI-FI credentials =>OK
-Applying WI-FI connection=>OK
-Checking provisioning status => spinner on the screen, spinning forever
Could someone please tell me what'I'am doing wrong / missing?
I put below the code and the terminal output.
Many thanks
esp_err_t wifiError;
esp_err_t wifiInit()
{
wifi_init_config_t wifiConfig = WIFI_INIT_CONFIG_DEFAULT();
if((wifiError=nvs_flash_init()))
return wifiError;
if((wifiError=esp_wifi_init(&wifiConfig)))
return wifiError;
if((wifiError=esp_wifi_set_mode(WIFI_MODE_STA)))
return wifiError;
esp_wifi_start();
return 0;
}

{
const char *service_name = "cb_boiler";

ESP_ERROR_CHECK(wifi_prov_mgr_start_provisioning(security, pop, service_name, service_key) );
wifi_prov_mgr_wait();
wifi_prov_mgr_deinit();
