I have been using this with no problem until I'm updating to ios14 and esptouch stop working and get error
client: sendto fail, but just ignore it
: No route to host
I try to run your example and it perfectly works. But when i try to implement to my own apps it is not working.
The problem is i am using kotlin file, but in your project is using java file. So please add example using MainActivity.kt (kotlin file)
Thanks
Thanks so much for making this package. It's just what I need for my ESP32 project. I build a test app using the connectivity package to get the device's Wi-Fi details then your sample code to configure the ESP32 device. My code to configure the device is:
print('setWifiConfig()');
if (_wifiName != null && _wifiBSSID != null && _wifiPassword != null) {
final ESPTouchTask task = ESPTouchTask(
ssid: _wifiName,
bssid: _wifiBSSID,
password: _wifiPassword,
);
final Stream<ESPTouchResult> stream = task.execute();
final printResult = (ESPTouchResult result) {
print('IP: ${result.ip} MAC: ${result.bssid}');
setState(() {
_remoteNotifyIPAddress = result.ip;
_remoteNotifyMacAddress = result.bssid;
});
};
StreamSubscription<ESPTouchResult> streamSubscription =
stream.listen(printResult);
// Don't forget to cancel your stream subscription:
streamSubscription.cancel();
} else {
print('Missing configuration value');
}but when I run the app, I get the following:

Have you seen this before? Do you know how I can fix this?
I am facing build error when using smart config and esp_touch package in same flutter project.. How i can remove it??
Error showing is

The 1.1.0-androidv2 of esptouch_flutter has been setting in pre-release for a year with the last updates to esptouch_flutter coming 18 months ago. What package are people using with similar functionality now?

I have changed the minSDK of android to 19 instead of 16 due to breaking features in newer versions of firbase libraries.
After changing the minSDK, esptouch stopped from detecting a successful wifi paring with esp8266.
I returned to minSDK 16, it worked fine again.
Hi,
"class SimpleWifiInfo {
static const platform =
MethodChannel('eng.smaho.com/esptouch_plugin/example');"
when I deal with this part on my own project I constantly get error. I cant acces to ssid and also bssid. I also tried to use wifi_info and connectivity but I didn't get any results. What should I do?
The application shows no devices found, even if the ESP32 board is in SmartConfig mode and the WIFI creds are hard coded to the function
Hey,
Multiple devices are not scanning, every time it's scanning only 1 device at a time.
esptouch_flutter: ^1.0.0
Flutter SDK Version- 2.16.1
Android Version- 10
I run the demo , and it's working on Android but not on iOS(13.3). Is there any configuration I need to do?

However when on debug mode the app runs flawlessly. What could be the issue?
Not support EspTouch V2.Do you have an updated plan？
newer version of android did not show the success message. bur the esp get connected to the wifi

I want to know which library are we supposed to use in arduino ide ??
"dispatch_get_current_queue" is deprecated and will be removed in a future release.
Hi, I've been unable to get this package working on iOS 15.1
Currently, I have been able to set up permissions correctly and get the multicast entitlement connected with the application. Even after following all the steps from 16, this has not been working.
I am concerned that whenever I call "flutter run", that the code signing that occurs there overrides the extra code-signing that was specified within the multicast setup thread.
Are the any steps I may be missing? Alongside that, is there anything that I can do to actually debug where the issue may lie as my app currently runs fine but just cannot connect to my ESP8266.
i'm trying the example code in the package on pub dev and when i press execute and receive the data on UDP SEND/RECEIVE
i receiving infinity of number one
can't fetch current wifi ssid and bssid.
getting the below error.
ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: MissingPluginException(No implementation found for method ssid on channel eng.smaho.com/esptouch_plugin/example)

HI,
Sir as I was going through the documentation and trying to figure it out to work I would like to inform you that the connectivity package has been updated and the breaking change is (ThegetWifiName,getWifiBSSIDandgetWifiIPare removed towifi_info_flutter).
Also sir I would really be thankful if you could suggest to me that I should put the GET wifi code in the wifi_info.dart file in your example code.
Thanks for your help and Thankyou for working on getting esptouch to flutter
🙌
See changelog in the connectivity package:
2.0.0 [Breaking Change] The
getWifiName,getWifiBSSIDandgetWifiIPare removed towifi_info_flutter.
I cannot build my project with this library included.
I'm getting this error:
Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:
- package:esptouch_flutter
For solutions, see https://dart.dev/go/unsound-null-safety
Can you please make this library to support null safety?
flutter run error:
esptouch_flutter-1.1.0-androidv2/android/src/main/java/com/smaho/eng/esptouch/EsptouchPlugin.java，uses or overrides deprecated API.

}
I was wondering if this package or part of it can get converted to native dart and thus work on all platforms, and can get executed from server side as well?.
What part of this library require the flutter framework and what part of it only required native dart code.
Null Safety and device count is not working.
When two ESP are in on it is connected to two ESP's but for only one ESP the data is Going .
Please Resolve it sir.
Hello,
When i connected successfully i see the ip adress of the module and the bssid information on my app.
How can i send some other information to app alongside the ip and bssid when connected successfully?
Dear author
Just a question about smartconfig.
Can i use smartconfig without WiFi BSSID input?
Thank you and have a nice day
Hey,
When I try to connect via the example from Github it works fine. However, there is one case where an error occurs:
If I enter a password that is wrong it will output "no devices found" after a minute. Then it goes back one page and when I enter the correct password, it still aborts after a minute and displays "no devices found".
Does anyone know what to do?

I tried to connect with different devices running iOS < 16 and it worked very well. But it could not match my iPhone XS Max and iPhone XS that have updated to iOS 16.
It would be great if you guys can release an update for iOS 16. Thank you a lot.

This is an email that I got:
I got some users reporting app was not working to find the ESP devices anymore. Investigating I realized they updated iPhones iOS version from 15 to iOS 16 and this is the issue. For some reason your lib is not working anymore on iOS 16.
I couldn't verify it yet, but in case someone is able to provide more info, this ticket would be the right place.
Hey,
Sometimes the device is not connecting and also multiple devices are not scanning/connecting.
I have also tried esptouch_flutter 1.1.0-androidv2, but the result is the same.
esptouch_flutter: ^1.0.0 and esptouch_flutter 1.1.0-androidv2
Flutter SDK Version- 2.16.1
Android Version- 10/11/12
Note-: Can you please provide some updates because we are facing that issue in our live application?
Good day,
When installing the package and running Flutter pub get the below warning appears.
The plugin
esptouch_flutteruses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it
since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
Will there be an updated version published in the near future?
Thanks
Etienne
