I'm new to react-native
I got one requirement, using react-native, we have to develop IOT app
Which will have
Bluetooth Mesh using Bluetooth Low Energy devices
Able to add and delete a device
can some one suggest me a plugin in react-native or javascript
As a start-up, we tried to use 2 plugins for our ble tool.
We started with Ble Manager but we had some limitations / bugs we coulnd't easely fix.
Then we tried Ble PLX which is, in my opinion, harder to use and slower but we didn't had the same issues. Our app is now in production with Ble PLX, we still have bugs on our side but the plugin is doing the job.

I am working with a peripheral device that communicates with an app via BLE UART.
To test and modify the peripheral’s firmware, I want to find a starter Android app that can communicate with the peripheral. I want to be able to modify the app along the way as I modify the peripheral firmware.
I got the Nordic nRF Toolbox app working in Android Studio and running on my tablet. However, when I look through this project it is far too difficult for me to understand right now. I have worked through several tutorials that offer a far simpler solution, however not a single one of them has ever fully compiled correctly at the end – I assume they are all out of date. So it has been a difficult journey so far.
I need the app to be able to scan for devices, and allow the user to connect to one – and then be able to communicate with the BLE peripheral via UART.
Can anyone point me to (a) a starter app with code on GitHub or similar, that they have tried recently, or (b) a tutorial / walk-through, that they have successfully completed recently?
Thanks in advance for any suggestions

I'm trying to develop a C++ application on Windows 10 (using Visual Studio 2017) capable of looking for nearby mobile devices and sending data (images) via Bluetooth. I'm new to Bluetooth applications, but from what I understand, the best solution is to use BLE and make the computer a GATT server.
For this purpose, I'm quite confused about which tool I should use in order to start creating my application, since most of the libraries I have found online are outdated or poorly documented (libblepp, gattlibpp, bluetoe).
I've also found this Windows API but I don't understand if this is what I should use and I don't know how to include it in my project neither.
Has anybody had some experience with this and could provide me some hints concerning the right tool to use, in order to get started with my project?
On the other side, I would like to develop a mobile app using Flutter capable of receiving the image and reading the data sent by the computer. flutter_blue looks like the best option to go with.
Edit: The idea for the application is the following: the computer runs an application that generates various frames. In the meanwhile, it constantly scans for nearby devices and, whenever a user makes a request, it sends the current output image to the device that makes the request.
The Windows API is what you should use if you write a C++ application for Windows. That will be the best supported option. If you happen to find some library that also does BLE it will probably just be a wrapper around the Windows API.
Unfortunately these APIs use the WinRT architecture which is not the easiest to set up but should work fine once you've managed to set up the environment.
(originally asked on GoogleGroup support)
If you are experiencing an issue please mention the full platform your issue applies to:
IDE: NetBeans
Desktop OS: Mac
Simulator: none, due to Bluetooth usage which is not available on Simulator
Device: Android phone
Bluetooth device: pedometer
It seems BLE support is unreliable. I turn on my Bluetooth device that I'm trying to connect to (a pedometer), then on the phone I start scanning for the device, and sometimes it picks up, sometimes not. If it does pick up, I try to connect using the address, and I get a "Could not connect to device". (incidentally, if I use isConnected(), it throws an exception saying it was never connected. I assumed it would just return false)
I'm trying to duplicate a native iOS app, which has no issue connecting to the pedometer every time.
I've been searching for a "best practices" on BLE comms, but can not find anything substantial. The link the Cordova docs are cumbersome due to requiring translation into the Codename One lib.
As you mentioned in the https://groups.google.com/d/msgid/codenameone-discussions/b2b022e0-47e3-4a4c-9c33-4998ce2ef65e%40googlegroups.com[thread in the discussion forum] the API is callback based and expects you to wait for a response from the device asynchronously.
This is because we ported a Cordova plugin to implement this functionality in a stable way. Since JavaScript doesn't support synchronous calls those weren't added.
We thought about extending the implementation but we also wanted to keep it as close as possible to the original so changes there can be brought in quickly.
So I'm trying to build an app that uses iOS 7 Multipeer Connectivity framework on the iPhone, but I'm now trying to connect the iPhone to an Android device using the same technology. Is this possible?
Is there something like Apple's multipeer connectivity framework for Android, or is there any way of connecting an iPhone to an Android device without using internet or mobile services, but using Wifi and bluetooth only?
Maybe a bit delayed, but technologies have evolved since so there is certainly new info around.
As iOS has yet to open up an API for WiFi Direct and Multipeer Connectivity is iOS only, I believe the best way to approach this is to use BLE, which is supported by both platforms (some better than others).
On iOS a device can act both as a BLE Central and BLE Peripheral at the same time, on Android the situation is more complex as not all devices support the BLE Peripheral state. Also the Android BLE stack is very unstable (to date).
If your use case is feature driven, I would suggest to look at Frameworks and Libraries that can do cross platform p2p for you, without you needing to build it up from scratch.
For example: p2pkit.io or google nearby
Disclaimer: I work for Uepaa, developing p2pkit.io for Android and iOS.
There is currently no way to connect with android over bluetooth, but you can connect with wifi using the Multipeer framework I believe. I know the developer of spaceteam accomplished this with his game. I'm not sure how exactly but it is possible.
Mutipeer connectivity cannot connect iOS and Android devices. Firechat & Spaceteam are using their own implementation.
More information here:
A couple of weeks after its iOS launch, FireChat made its debut on Android. Since Android doesn’t support Apple’s Multipeer Connectivity Framework, developer Open Garden had to build its own mesh networking technology to enable off-the-grid messaging across Android devices. However, FireChat messaging hasn’t been possible between iOS and Android. That is, until now. Open Garden has just updated FireChat to allow for off-the-grid messaging even between iOS and Android devices. While it declines to reveal the exact details of how it managed to make Apple’s multi-peer framework and its Android mesh network connect with each other, Open Garden has told TechCrunch that its cross-platform capability uses peer-to-peer Wi-Fi and Bluetooth personal area networking.

Google Nearby can do it. To cross platform, Google Nearby Message Api can do it.
I have been searching for a while now and decided to post a question here to see if someone had already traveled down this specific road.
I am developing a bluetooth enabled device, using the Bluegiga BLE112 chip. They announce this chip to be easily used with iOS devices (and this was our main reason for choosing it)
The device will need to communicate with an App, that we need to be developed for iOS, Android, Windows Phone, and Blackberry. Due to this need, I've decided to use Rhomobile, as it seems to be the only one that supports developing BT apps for iOS without having to develop further plugins.
I only need to send small messages (like commands, small strings) and sometimes a bigger file to the device's internal memory.
On Rhomobile's BT documentation, they state that for iOS it is only possible to comunicate between iOS devices ( i'm thinking that they say this because of the MiFi limitations imposed by Apple, but that using Bluegigas chip are not a problem...)
My question is:
Since Bluegiga's documentation has examples of devices communicating with iOS using their chip, i should be able to develop using Rhomobile and not suffer from the limitation stated above. I wanted to be as sure as possible before making my company spend money ordering the chips and development board and what not..
Has anyone tried this, is my thinking missing something?
Thank you all for your time.

Good Question, I think I can understand the reason for your confusion.
The main reason is many people/products/frameworks does not clearly mention if they are talking about Bluetooth Classic or Bluetooth Low Energy (BLE).
These are both 2 different things and even thougfh they are called "Bluetooth" one cannot talk to the other.
(Some devices can be both Classic and Bluetooth Low Energy, which allows it to connect to either types)
Ok now comming to your Question :
THE bluegiga dongle is BLE
The Rhomobile is refering to the Bluetooth Classic version of the API.
On iOS the BLE APIs are open to applications, but Classic is limited on iOS , one way for Apps to use Classic Bluetooth on iOS is via the Gamekit APIs but that is possible only when talking with iOS devices, so it wont connect to another Android or Win device that is also Classic.
Needless to say with BLE APIs you cannot connect to calssic anyways.
The bluegiga examples are BLE examples, and apple also has good documentation and examples / samples on how to use BLE so yes it is easy to build a device and app using BLE on iOS.
There is nothing special abut any particular chip yo ucan use any BLE chip - there are many vendors today.
BUT Android (and I guess Windows as well) does not yet have BLE APIs for applications to use :( (Bit I think is is comming soon :))
So I hope this clears things up a bit.
