Wifi connection to a network without internet access
esleybonomo opened this issue · 3 comments
I have a project that connects WiFi to an IoT device, generating the APK in --dev-client mode, everything works perfectly, however when I generate the APK for testing in QA, it doesn't work, it seems to create a second network and it doesn't connect to the available.
useEffect(() => {
(async () => {
const granted = await PermissionsAndroid.request(
PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
{
title: 'A permissão de localização é necessária para conexões WiFi',
message:
'Este aplicativo precisa de permissão de localização, ' +
'pois isso é necessário para digitalizar redes Wi-Fi.',
buttonNegative: 'DENY',
buttonPositive: 'ALLOW',
},
);
const { status } = await Location.requestForegroundPermissionsAsync();
if (status !== 'granted') {
return;
}
const location = await Location.getCurrentPositionAsync({});
enableWifiUsage().then(() => {
console.debug("WiFi local ativado. Conectando...");
connectToWifi(macAddress, setIsLoading, wifiGatewayPassword, setNewMacAddress).then(() => {
console.debug("Conectado!");
getDeviceConfiguration().then(() => {
console.debug("Carregou os dados de rede do equipamento.");
},
(e) => {
let msgError = "Erro ao carregar dados de rede do equipamento. " + e.error;
Toast.show({
type: 'error',
text1: msgError
});
throw new Error(msgError);
});
});
});
})();
}, []);
const wifiGatewayPassword = async () => {
const response = await services.gatewayWifiPassword(macAddress);
const wifiPassword = response.data;
setGatewayPassword(wifiPassword);
return Promise.resolve(wifiPassword)
};
const getDeviceConfiguration = ( async () => {
const responseData = await services.GetDeviceConfiguration();
const response = responseData.data
setSsid(response.net_ssid);
setPassword(response.net_pass);
});
I created WIfiManager.js
import WifiManager from 'react-native-wifi-reborn';
import Toast from 'react-native-toast-message';
export const enableWifiUsage = async () => {
try {
await WifiManager.forceWifiUsageWithOptions(true, { noInternet: true }).then(() => {
console.debug("Todas as solicitações de rede serão roteadas para a rede WiFi sem Internet.");
});
} catch (error) {
console.error("Falhou em permitir o uso de Wi-Fi sem internet: " + error.message);
}
};
export const disableWifiUsage = async () => {
try {
await WifiManager.forceWifiUsageWithOptions(false, { noInternet: true }).then(() => {
console.debug("As solicitações de rede serão roteadas para a rede padrão.");
});
} catch (error) {
console.error("Falha ao desativar o uso de WiFi: " + error.message);
}
};
export const connectToWifi = async (macAddress, setIsLoading, wifiGatewayPassword, setNewMacAddress) => {
const newMacAddress = macAddress.replace(/:/g, '-');
setNewMacAddress(newMacAddress);
const ssid = 'Connect Lite ' + newMacAddress;
setIsLoading(true);
const password = await wifiGatewayPassword();
try {
WifiManager.isEnabled().then((enabled) => {
if (!enabled) {
WifiManager.setEnabled(true);
console.debug("Wifi Enabled");
}
})
await WifiManager.connectToProtectedSSID(ssid, password, false, false).then(() => {
Toast.show({
type: 'success',
text1: 'Conectado à rede Wi-Fi',
text2: ssid
});
});
} catch (error) {
Toast.show({
type: 'error',
text1: 'Erro ao conectar à rede Wi-Fi do gateway',
text2: error.message
});
} finally {
setIsLoading(false);
}
};
Can anyone help me identify where my error is?
I found solution.
My suggestion is to include this in the lib in some way, so you don't need to create a plugin to change the AndroidManifest and do the prebuild generating the android and ios folders.
File plugins/network_security_config.xml
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">192.168.0.1</domain>
</domain-config>
</network-security-config>
File plugins/network_security_config.js
const {AndroidConfig, withAndroidManifest } = require('@expo/config-plugins');
const {Paths} = require('@expo/config-plugins/build/android');
const path = require('path');
const fs = require('fs');
const fsPromises = fs.promises;
const { getMainApplicationOrThrow} = AndroidConfig.Manifest
const networkConfig = config => {
return withAndroidManifest(config, async config => {
config.modResults = await setCustomConfigAsync(config, config.modResults);
return config;
});
}
async function setCustomConfigAsync(
config,
androidManifest
) {
const src_file_pat = path.join(__dirname, "network_security_config.xml");
const res_file_path = path.join(await Paths.getResourceFolderAsync(config.modRequest.projectRoot),
"xml", "network_security_config.xml");
const res_dir = path.resolve(res_file_path, "..");
if (!fs.existsSync(res_dir)) {
await fsPromises.mkdir(res_dir);
}
try {
await fsPromises.copyFile(src_file_pat, res_file_path);
} catch (e) {
throw e;
}
const mainApplication = getMainApplicationOrThrow(androidManifest);
mainApplication.$["android:networkSecurityConfig"] = "@xml/network_security_config";
return androidManifest;
}
module.exports = networkConfig;
And in app.json include it:
"plugins": [
"./plugins/network_security_config.js"
],
And it's important run npx expo prebuild --no-install

I think it is the problem. The differences of connections.
Look the description of TiqueTaque_180... : "Disponível via Setup TiqueTaque" (Available via TiqueTaque)
if connect manually in network settings of device appear a different description:
Look the description of TiqueTaque_180... : "Conectado ao dispositivo. Sem acesso à internet." (Connected to device. Can't provide internet.)

(NOT WORK) Thanks. In my case, I am not using EXPO. So I tried this:
PROJECT/android/app/src/main/res/xml/network_security_config.xml:
<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
<domain-config cleartextTrafficPermitted="true">
<domain includeSubdomains="true">192.168.4.1</domain>
<domain includeSubdomains="true">http://192.168.4.1</domain>
</domain-config>
</network-security-config>
PROJECT/android/app/src/main/AndroidManifest.xml:
<manifest xmlns:android="http://schemas.android.com/apk/res/android">
<!-- your existing permissions ... -->
<uses-permission android:name="android.permission.INTERNET" />
<application
<!-- your existing options ... -->
android:usesCleartextTraffic="true"
android:networkSecurityConfig="@xml/network_security_config"
>
</application>
</manifest>
Some solution?
