[Help] Buying Bluetooth Module.

[carlosr]

Hello,

I'm starting a small project to make a "RC" car controlled by android via Bluetooth. I've found 2 Bluetooth modules that I like:

http://www.adafruit.com/products/1588

I would like to know what is the difference between them. I will be most trading 'Strings' between the arduino and the android. Also I would use this into another project that already uses SPI and the arduino mega, again to trade mostly strings.

Greetings.

I think both devices are capable of doing what you want. Although both modules should have similar transmission range, the Bluetooth LE module will use less power for communication.

However, the BLE standard is still fairly new and the tools are limited. We are recommending this for advanced users only at this time:

Please note: There is not an Android version of the Adafruit Bluefruit LE App available (our native BLE application) at this time,however you can use Nordic's Android nRF UART application with the nRF8001 Breakout on BLE capable Android devices (Nexus 4, Nexus 5, Nexus 7, etc.) for sending/receiving data. This is a product for ADVANCED USERS - At this time we recommend this product for people who are either OK with using the apps available (Nordic's UART demo or our Bluefruit LE Connect) or are comfortable with writing iOS apps (and can refer to our App repository). We do not have a tutorial for writing your own iOS or Android BLE app at this time, don't worry we're working on one :)
