How do I send files to and from devices using NFC beam. I tried the Google tutorials
to send a file and receive a file
I searched around the internet and didn't find any good tutorials.

I'm going to set up any open-source XMPP server such as ejabberd or prosody to use it within a small group of people like a working chat with no federation. XMPP client monocles claims it supports voicemails. At the same time I've found no solution for transferring files like images or voice messages in XMPP. Is there such a solution? Or should I move to another technology like matrix? The only condition is peer-to-peer encrypted messaging with an ability to transfer images/voice messages. Voice calls are not necessary.
no solution for transferring files like images or voice messages in XMPP
Really? Gajim's chat window has an clip button to send and random local file (text, image, whatever). Obviously many other XMPP clients have file transfer support.
The only condition is peer-to-peer encrypted messaging
As seen in https://gajim.org/
End-to-End Encryption Chat securely using OMEMO, PGP, or OpenPGP.
If Gajim has it, then other clients do it too
I propose you:
Install ejabberd or prosody in your desktop machine (there are installers, container images, packages for the most common operating systems)
Try several well-known clients (Gajim, Conversations, Psi...) to check if the features you want are available as you desire.
If the feature work with some clients, then check if they work correctly in Monocles Chat.
What i want to do is get some kind of nfc reader so i can put my smartphone on top of it and it sends some data to my server. For example i have app where i store my name and when i put my phone on top of the device it sends "John says hi" to my server.
I am not sure which keywords i should use to find this kind of device but i think that there should be devices like that because there is mobile pay etc.
And if there is not any devices like that is there any alternatives for example device that works with bluetooth?
You could simply buy a cheap NFC-Tag and program it, so that it opens an URL on your Server or start an App which sends something to your server.
They are very cheap and easily programmable.
I'm trying to come up with a solution to this situation:
Imagine you are in an area and you do not have any cell phone service but you do have Wifi.
The ask is to have a user that only has data to be able to text a number (via iMessage) and get a confirmation code in return.
The first tool I thought would be necessary for this would be Twilio - but it seems like Twilio only sends over standard SMS.
Are there any other tools out there anyone have used that would work in this idea? Something similar to Twilio but only ran on data?
Twilio developer evangelist here.
This is something you can only do as the phone provider or network provider (using Three in the UK allows me to make phone calls over wifi with no phone signal, for example).
The two things you can do is either build yourself a native application that you can send messages to using push notifications or send messages to existing native apps, like Messenger, Viber or Line.
i manage to send my temperature sensor data to Google Drive by using Arduino. I am currently stuck in sending message from arduino when my sensor hits a predefined value. I am able to send SMS from Google Drive by using Twilio and some codes to the script editor. By any chance, am i able to connect my Google Drive back to my arduino as i am using 2 different spreadsheets (one for the sensor data, and the other for SMS)
Thanks in advance.
I am creating a small VB project and I want to send some information through SMS. I tried to find solutions in here many threads but can get one.
I am using Huawei E1731 3G USB modem, which is capable of sending and receiving sms through its official software. How can i use the modem to send a fixed message to particular number by getting the number from text box in a form?
Hopefully you are using VB.NET and not VB6.
Here is a solution in C#.NET which you should easily be able to convert to VB.NET :
