I have a question, I want to buy a beacon and send the signal from the beacon to the flutter application and then do something.
Is that possible with flutter?
Thank you very much!
Yes, it is possible. I tried https://pub.dev/packages/flutter_beacon for myself interest once when covid-19 declared a pandemic by WHO to solve Handshake problem.
I was converting the existing device as a beacon and then used "flutter_beacon" package to get the list of beacons in a defined region. So yeah, it is possible to do it flutter also. You can customize it as per your need further. But basic things are possible like getting the list of beacons in reason.
If asked whether or not, the answer is yes. but there are some obstacles or limits, such as Bluetooth will not scan in the background as in this article, this is indeed from Android and IOS which causes the limit. I am also working on this project, but there are still some problems as I have described above.
This link also can help Beacon scanning in background - Android O

I am developing in flutter a stock market alert app that checks in the background a certain stock price and send a push notification. I used the background_fetch library but that is only able to fetch the price every 15 minutes, and have some reliability issues on ios.
Therefore, I was wondering if there was another way to implement the same feature.
You can try android_alarm_manager package from pub dev, but it is only available for
(you guessed it) android. This will solve the 15 min frequency I hope it works for you. On a side note I also need a function to run when user enters a geofence when app is on background and I still haven't found a solution. Because in my problem it shouldn't run every x minutes but when sth is triggered.
there is this answer of a similar question but on IOS but it work the similar way on android hope this help and i am sorry for this negative answer :(

I am developing an ARKit application using World Tracking. However, the worldMappingStatus is always limited. Does anyone have the same issue or know how it can be solved?
Best regards,

That's not normal but I'd need a bit more info to properly answer your question. 1- How do you know it's always limited? 2- are you moving the phone around when you launch the app to "understand the surroundings" 3- what code have you tried?
Is it possible on iPhone to create a data connection by specifying the SSID of the network?
Is it possible from application to check the signal/availability of the network with specified SSID?

What you're trying to do is sadly not possible without the usage of private (undocumented) API-s.
Hopefully Apple will provide this kind of functionality (with users permition) though i don't think this is bound to happen soon.
If you want to research this topic further the first place to check would be iphone-wireless - the home of Stumbler which shows a nice usage of MobileApple80211.
Hi im still not 100% with xcode and android. I have the Droid X and I code with Xcode. My dad is on the Fire Dept. and wants me to code an app for either the android and/or iphone that detects the dispatch's radio signal and receives it and streams it in the background so the firemen could listen to the radio on their phones so they wouldn't have to carry their bulky radios with them everywhere. If there is someone that could help me or point me in the right direction, I would greatly appreciate it.
Thank you, Halokllr
Some bad news Halokllr, the iPhone doesn't have a radio chip, and the FM radio included in some Android models will probably not be able to physically pick up emergency broadcast signals. In order to do what you are suggesting, you would need a web service of some kind that already exists and streams audio for the emergency signals you're interested in. Now there ARE some services like this, though I would strongly suggest that if it is intended to be used for actual first responders that you very carefully research their timeliness guarantees. Some of them may be hours behind live events. Check out http://www.radioreference.com/ as an example service provider.
Is it possible to connect non iPhone device (like Blood sugar monitoring) with the iPhone to display its data.
So my First Question is:
1.Is it possible
2.If yes can you provide some links for development or Example codes.
Thanks for any kind of help in advance...
You can get the answer of your question here
P.S. The link is same as it is on the comment of the answer.. But since I didnt noticed the comment and was searching for the long time. So for the ones who havent seen Brads comment in the question. I have passed the link in answer.
Thanks
Do you want code or an application? Search for Bump on the AppStore. If you want code, I'd suggest looking at the GameKit framework however I don't know if you can use that to talk to other devices or not...
I would imagine it's definitely possible. A protocol like Bluetooth or WIFI would be device-agnostic. I guess it would depend on the device that you want to interface with your iPhone. Do you have a device in mind?
