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???
Bluetooth is a protocol heavy standard. If the mobile phone you are using doesn't implement the serial-port profile, you are going to have to write the stack yourself. (Hint: Most mobile phone platforms do not support it.)
Xbee will require some form of communication as well. If you want to connect anything via USB you will need a phone that implements "Host" mode or you will have to build the "Host" in your hardware. Again, you'll need the software stack to support serial devices. (In a case where a mobile device supports working as a "USB Host" this is more likely.)
Where you need to start is, finding a mobile device with a general purpose I/O interface, so you can talk to other devices.
did you find the answer to your question, i also want to try to connect my mobile via bluetooth to my xbee module. let me know if you found any hint that could help me.
