One of the most questions received from our Community has been about using the 3G/GPRS shield for Arduino / Raspberry Pi to make video calls. In this video, you will be able to know how to do it with the Audio/Video Kit.
We make a call from our Arduino to our mobile phone. The video took from the camera in the Arduino is showed in the mobile phone in real-time.
In order to work with 3G Shield, you can take a look on this tutorial. It explains how to use it with AT Commands through a Serial Terminal like Cutecom or GTKTerm.
The basic commands are:
- AT+CREG?: it returns "+CREG: 0,1" orĀ "+CREG: 0,5" if we are connected through our own network (1) or in roaming (5)
- AT+CCAMS: we activate the camera
- AT+VPMAKE=<phone number>
- AT+VPEND: hang up.
Note: in this video, we type "AT+CMUT=1" and "AT+VMUTE=1" to mute the microphone and the speaker of the video/kit in order to avoid interferences.
