1  Using Arduino / Project Guidance / Xbee vs Bluetooth with mobile on: March 28, 2011, 05:59:18 pm
Hi everyone!

In my project i need to implement communication between 2 wearable accelerometers(one in each hand) and a phone device. For these purpose I was thinking to make use of the arduino Pro Mini 3,3V along with XBee modules

Thw question is whether the Xbee can communicate with mobile devices.In case this is not feasible(haven't found anything while searching) is there any other device with which Xbee can communicate,and this device can have a (mini)USB port thus enabling its hacking up with a mobile??

Do you think implementation with bluetooth could be better???

Thanks in advance!

there is already a project in the lab of my university that uses two hand wearable modules each including:
a 3 axis-accelerometer, an Arduino Pro mini 3.3V and an Xbee 1MW with Antenna.  These modules send one each other data,compare them and display on a screen that the one of the two modules bear.

Now,I need these data to be sent to a mobile(preferably smartphone,PDA) wirelessly and to be displayed there instead of the small screen previously used.

Should I keep the existing hardware and sent it with the Xbee module?So,are there mobile phones that communicate wirelessly with Zigbee
( 802.15.4 IEEE) and if so,do they need extra hardware to be implemented?

The second opcion would be to abort the Xbee modules and replace them with bluetooth that all mobile include.

What seems better?Or of course any other ideas?

Thank you in advance!
In this case what bluetooth hardware is needed given the use of the Arduino Pro Mini 3.3V? As you see,there is a space limit because of its a wearable "watch" layout.
