Arduino ---> Android Bluetooth

Hi All,

I read that it’s possible to have the Arduino talk to an Android tablet via Bluetooth, however I am stumped on one thing. What library can be used on the Arduino to talk to the Android Tablet? Also what is the most common bluetooth device I can attach to the Arduino to communicate with the tablet (or anything in fact) ?

Thank you in advance

No library required

Hi Nick, one more question, if I test my project on an Asus 7 inch tablet, and I want to make the final production project on a Nexus 10, will the code still work via bluetooth? I'm trying to utilize the NFC reader to read a card, and send that to the Arduino. I want to test on a cheaper device first.

Essentially, Android is Android, and Bluetooth is Bluetooth, So what works on the Asus shiould be fine on a Nexus. This also certainly applies as far as Arduino is concerned, as all it is doing is having a conversation with Bluetooth.

utilize the NFC reader to read a card, and send that to the Arduino

I don't know what an NFC is but, initially at least, this sounds much more like an Android problem than Arduino. However, with the only file transfer system I know of, the PC does all the work. I guess Arduino could do a similar job, but I'm not sure about the practicality.

NFC - Near Field Communication is an RFID varient. http://en.wikipedia.org/wiki/Near_field_communication
Just another means to transfer information like Bluetooth, but NFC is well known for reading cards and other type of tags which have information on it.

I'll poke around and see if I can play around with this. I just purchased a Bluetooth module for the Arduino so I can start with my project. Thanks for your help

OK. You will get plenty of support with file transfer here.
