Communication between android tablet and iphone - iphone

hii,
I want to communicate between an iphone and an android tablet. The tablet as well as the iphone work on different 3g data services. Can any body give me an idea how to communicate and send messages between the devices...

You could use the Bump SDK, which is available for both iOS and Android:

How to make flutter_blue to scan bluetooth devices other than Bluetooth Low Energy (BLE) devices like mobile phones or PCs

The problem is that I am trying to scan for other mobile devices near me using flutter_blue but it is made only for devices like earbuds or speaker. So it is not able to show me other devices in the scan results.
Is there any solution for this?
Is there any other package available for doing this?
I Have tried everything but it has no solution.
You can not connect with other PCs and devices via Bluetooth connection, android does not give permissions for this because of security reasons, you can only connect with BLE devices with any Flutter Bluetooth library.
You can check Android Documentation For more.

Flutter: Is it possible to make a P2P connection with nfc_in_flutter package?

I would like to send a message from an Android device to an IOS device using NFC.
I found multiple NFC packages and tried out example app from nfc_in_flutter but was not able to send a message between 2 phones.
Do they only support reading and writing to NFC-Tags or am I missing something?
iOS does not support Peer to Peer NFC even natively and Android has deprecated support for it in Android 10 (Android Beam).
So you are not missing something, iOS lags behind Android and only in iOS 13 supports reading/writing where as Android has supported reading/writing and Host Card Emulation for a long time.
Better to use Bluetooth or Wifi Direct

bluetooth GATT over BLE for iOS and Android?

I have a project that needs iOS/Android APP to communicate with embedded side via Bluetooth Low Energy(BLE) to transfer small amount of data. My embedded side is CSR chip which supports the dual mode.
Does anyone know is that possible for both Android and iOS to support this GATT over BLE? Any fee like joining developer program?
I think Android side should be OK, but I am very new to iOS and don't know it is easy to do so.
thanks
Yes Android supports GATT over BLE. Yes iOS supports GATT over BLE. Yes Apple requires you to be an Apple Developer in order to develop iOS apps and it costs $99/year. You will also need an Apple computer to do the development.

Ibeacon app developing

Just started reading about this ibeacon that apple is selling out to retailers. If I wanted to created an app that connects to these beacons.. how can I do so? Cant seem to find any apis or any help for doing this, it is a relatively new technology. Also, can Android devices also utilize this technology?
Apple has an app called AirLocate that they released at WWDC this year. If you search on "AirLocate" you can find it online.
It is an app that lets you turn your BLE-capable iOS device (iPhone 4S or later, iPad mini/ iPad 3 or later, or 4" iPod) into either a beacon or a beacon detector.
With that source it's quite easy to figure out the basics of iBeacon programming.
As the other poster said, the newest Androids are able to detect beacons, but so far the firmware does not support sending as a beacon.
Yes, Android devices can interact with iBeacons using Radius Networks' Android iBeacon Library.
You can find a table that compares the APIs for both Android and iOS on this page. You may also want to Google for a tutorial.

Does the iPhone sdk support l2cap bluetooth sockets?

Does the iPhone sdk support l2cap bluetooth sockets? Any additional information about SDK classes, etc would be greatly appreciated.
The latest CoreBluetooth does expose L2Cap through CBL2CAPChannel: https://developer.apple.com/documentation/corebluetooth/cbl2capchannel
It can be opened from a CBPeripheral: https://developer.apple.com/documentation/corebluetooth/cbperipheral/2880151-openl2capchannel
No.
There are no direct support for Bluetooth APIs in the SDk,
REfer the game kit programming APIs for application development with Bluetooth for peer-to-peer gaming
Other than than you will have to join the Made for iPod/iPhone/iPad program to get access and develop bluetooth connected accessories
Bad news from MFI FAQ (2014):
Q: I want to develop an accessory that communicates with an Apple device using only Bluetooth Low Energy. Do I need to join the MFi Program?
A: No. Accessories which connect to an Apple device using only Bluetooth Low Energy/BTLE/Bluetooth 4.0 or standard Bluetooth profiles supported by iOS are not part of the MFi Program.
I'm developing an app to connect with a L2CAP device on Android, now I'm studying porting on IOS but I found this issue.
For enabling a device to talk by Bluetooth, it must integrate the Apple authentication chip into device and must be able to connect with built-in Apple's Bonjour discovery service.
No L2CAP for any device... Sorry!
