B4R Question project ideas

[Leif N]

hallo there!
I am new here, but not with Arduino and electronics.
I want to construct a home automation system with a arduino (due) and a gsm-shied.
my idea is to control the arduino from a app in a iPhone or android cell phone.

maybe I can use B4A to make such a app.
the thing a want to be able to do is, to fetch data remotely (air temp and humid) to my app on my cellphone. Thing number two is that I want to take a picture with a dig. camera connected to the Arduino and send it to my cellphone. Maybe MMS?

I want to make a request with SMS or call to the arduino , and then it should send the requested data.
This way the arduino doesn't have to be connected to internet, but only to the public mobile network.

can anyone give me some help?
is it possible?
are there any others that have done something like this?

There are many examples of communication between iPhone or Android and Arduino.

the thing a want to be able to do is, to fetch data remotely (air temp and humid) to my app on my cellphone

This is simple. Check this example: https://www.b4x.com/android/forum/threads/esp8266-udp-bmp180-simple-weather-station.70243/#content

Thing number two is that I want to take a picture with a dig. camera connected to the Arduino and send it to my cellphone. Maybe MMS?

I never connected a camera to Arduino. I think that it will be easier to implement it with Raspberry Pi or an Android phone instead.

If the board is in the house then it will be easier to connect it to the local network than to use SMS or MMS.

thanks!
I don't understand how the data is transferred from the Arduino gsm shield to the cellphone?
I have a small cottage where I want to place my arduino with sensors and want to remotely to see the temp and humid on my cellphone.
its 250km to my cottage from my home and there is no wifi network or internet connection in my cottage.

the camera problem, can be solved later.

You need to call GSM.SendSMS with the data you like to send: https://www.b4x.com/android/forum/t...-the-arduino-with-sms-messages.66770/#content

The Android app will intercept the SMS and parse the data.

 

[Leif N]

yes!
now I got a start to this - thanks!

I wonder how it works with GPRS.
can I send a variable from the Arduino with the shield to my app on the cellphone with GPRS?
if that's possible I don't have to use SMS.

 

[Erel]

No. The code doesn't allow you to open a socket over GPRS. Even if it was possible you cannot directly connect to the Android device over a mobile network.

Thanks!
I will start my project with SMS as the communication between the Arduino and the android phone.
