Hi All,
I have been googling around but cannot find specific answer as to whether smartphones have rf transmission capabilities?
What I was thinking, if smartphones have rf transmitter/receiver capabilites, then I can receive data from my arduino on my samsung infuse through rf wireless sensor.
In short, please let me know if the smart phones are capable of receiving rf wireless data?
And if it is, do you know of a link/tutorial I can go to see how to do this with android? I found couple of results but with only bluetooth.
Thank you.
yes, most smart phones have WiFi and Bluetooth.
In addition to the Cellular link.
All are “RF”
@ stevech. Thnx for the reply.
I got confused. I was confusing IR with RF. Ok so if I have a 315 mhz transmitter(http://www.sparkfun.com/products/10535) on an arduino, is it possible to use a smartphone as a receiver? If so is there any tutorials you know about for this purpose?
I googled it around but did not find what I am looking for?
The iPhone does not contain a 315 MHz receiver.
I never mentioned about iphone. I have an android. But that’s not the issue. My question is how can I use a smartphone (in this case android) as a rf receiver? In other words if I have a rf transmitter that has the same frequency transmission, then how can I setup my phone as a receiver?
Also what frequency transmitter will I need so that the phone and transmitter can communicate?
Does anyone know of a tutorial that kind of explains this concept?
Thank you.
Sorry, misread your post. To match the phone with a given transmitter, you need to match the radio frequency AS WELL as the transmission protocol (ASK, FSK, OOK, QAM, etc.) in order to send & receive data. These are the subjects of a year or two of engineering courses, so you are unlikely to find a simple tutorial. But you might begin by exploring an example such as Zigbee: http://en.wikipedia.org/wiki/ZigBee
If you want a simple setup for experiments, buy a cheap 433 MHz transmitter/receiver pair from Sparkfun, a couple of Arduinos and play with the VirtualWire code examples. See http://www.open.com.au/mikem/arduino/VirtualWire.pdf.

Your Android device probably has IEEE 802.11 WiFi and IEEE 802.15.1 Bluetooth capability. Both use the 2.4GHz band, in different modulation methods.
Commodity items allow you to communicate via these two methods between the Android device and some other device complying with the same IEEE standard. Choose your standard, then go shopping for radio modules, many of which are sold here.
yes I also have the same question I would like to know how can I connect my 2.4 ghz transmitter so it can communicate with my android phone and is it even possible ???
