I'm a beginner in react native and I'm working on a mobile app for school. Within it, I need to send and receive data (draw graphs) from the cloud. We use cloud services from Mathworks - Thingspeak. Would you please advise me on how to start this communication? Is it necessary to set this communication on every screen where graphs will be displayed or send data? Is it possible to use write & read API keys for this task?
Thank you for every answer
You can use REST API for communication,

For write: https://www.mathworks.com/help/thingspeak/writedata.html
There are example requests on both pages.
You don't need to install a separate package, you can do it with fetch
Let me know if you succeeded, or I can help again!

I need to develop an app using React Native which will get some data from Amazfit Stratos smart watch.
The smart watch is connected to the phone via bluetooth and has an application "Amazfit" where it actually gets the data that I need (i.e. step count, heart rate, etc.). After a lot of research (google and youtube), I have not encountered a way to import the data into my application. Since I haven't started making the application, there is no code to show. Can any one provide any basic solution to this problem?
My guess is (if it's possible):
Make my application communicate with the smart watch
Make my application communicate with Amazfit Android application
Any help greatly appreciated!
I need to continuously sync with backend API. What are the changes done in backend it should be reflect back to front end in vue? How to continuously sync with API? Is the only way to set interval and call API or is there a better way?
If you only require that the frontend receive information from the backend then you could use something called a stream. You could create a readable stream that your Vue app listens to.
https://developer.mozilla.org/en-US/docs/Web/API/Streams_API
If you require that the front and backend communicate with each other, then you could use web sockets:
https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API
A very popular javascript library for this is socket.io.

There are a lot of guides on the internet about how to set it all up. If you have any further questions, I recommend creating separate questions on SO.
i use Key id for update real time table from json file .
I am developing an app that can go through an array of phone numbers and call one by one. And when the user answers the call, an automated voice should be played. Can anyone please help me by giving some suggestions to develop this app. Please mention any useful packages that I can use for my use case.
This cannot be done only React Native. You have to use third party API. As there will be so many calls so it will be better to put that in backend. Here are some API you can use :-
Twilio
Exotel
Tropo
I am trying to build an application which works this way: I as a user want to start a call with another user. The way I want the connection be made is by random. So it will connect to one of the many clients out there by random. Also when other clients try to make a call, it should connect to another random client and so on. I want those phone calls be made via application(such as WhatsApp) not as a phone call.
Now, the question is; is Twilio a good approach for this purpose?
If yes can you tell me which of their feature would fit my app the best?
Thanks for any suggestions!
Twilio developer evangelist here.
I can answer that Twilio would be a good approach for you to do this within your own application. I'd recommend using Twilio Video to build this as it allows cross platform communication via audio or video (in your case, you may not need the video, but this will give you the best audio quality).
As an example, my colleague Dominik built a video roulette application. It is the case that the interface was built in JavaScript for the web, but the idea would be the same for a native app. The code for the server side part of the application should give some insight into how to connect random pairings.
It's also possible to integrate Twilio Video with CallKit and Connection Services so that you can make outbound calls to other devices that ring like a real incoming call.
I'm developing an IoS and Android app using react-native, and am now starting to consider all the aspects of user registration, so that typically the person will provide some credentials, and then get sent an email (or possibly sms) enabling them to "verify" their account, after which point they are a registered user.
These registration processes (and subsequent emails/sms's seem to be fairly common , so I'm wondering if there are any API's which anyone has come across which make the job of creating the registration/activation process easier m rather than writing code from scratch ?
Many thanks in anticipation
It depends what you want when you ask for an API. If you're developing backend as well you can use Auth0.
If you want just to implement frontend, I guess you have to write your own code. Consider using something like redux or mobx to store your email and other things after logging in.
Anyways the REST part you have to write on your own. As for views you can google for it, for example there's react-native-login-screen
