We have recently got adafruit bluefruit le which looks like
Now we are interfacing it with Lilypad ATMEGA 328 as the same shown below link::
LilyPad interfacing with bluefruit
For configuration of bluefruit we are using this link.
Here it is mentioned
connect the CTS pin on the Bluefruit to ground if you are not using it!
But we are not able to find CTS pin on the Bluefruit. Please suggest if you have any idea.
On Flora board CTS pin connected to the ground on hardware level. CTS not used on this board by default.

I am building some software on mac os x that uses iobluetooth and corebluetooth to connect/manipulate bluetooth devices.
Like most Bluetooth speakers, the Bluetooth classic network is hidden unless pairing but often the Bluetooth Low Energy network is visible.
I was wondering if there was some way to find a link to the Bluetooth classic section through the Bluetooth Low Energy network and use the details to establish a connection to the Bluetooth classic network.
I am assuming that your speaker is supporting both LE and classic Bluetooth profiles.
So you can connect le first by giving BD_ADDR and all the details for your speaker and later on you can change the transport to classic Bluetooth such as A2DP or SCO.
Thanks.

I am thinking of doing a project with wearable electronics.
First off I was wondering if you can connect the HC-6 Bluetooth device to the Lilly Pad, to send data to a computer via Bluetooth? or do I absolutely have to buy the "expensive" Bluetooth Mate?
Second, if the above is not possible, what is the smartest and cheapest solution for sending data from a Lily Pad to a computer?
I don't see why not. First off, this tutorial shows you how to attach the HC-06 to an Arduino Uno: http://www.instructables.com/id/Add-bluetooth-to-your-Arduino-project-ArduinoHC-06/?ALLSTEPS
Even though you are using a Lilypad, the pins are the same. Here is a pinout diagram for the Lilypad: http://figures.oreilly.com/tagoreillycom20090710oreillybooks308088I_book_d1e1/figs/I_mediaobject5_d1e21363-web.png
This does a decent job of explaining Bluetooth serial communication for Macs: https://decyborg.wordpress.com/2013/09/08/bluetooth-serial-communication-with-arduino-jy-mcu-bluetooth-and-macbook-pro/
Or you could check this out for Windows: https://www.microsoft.com/en-us/store/apps/bluetooth-serial-terminal/9wzdncrdfst8
Hope this helps.

I'm trying to create an Arduino bluetooth remote that can connect with my Mac (and potentially other devices) and basically transmit a few distinct signals back and forth at the push of a button (or Arduino pushbutton). I want to create a remote to control a web app I've built, basically a controller for a game.
I have an Arduino Uno Rev3 starter kit, an RN-42 bluetooth module & a 1sheeld from Google Play, and a Macbook Pro.
Could anyone suggest good guides or online tutorials that can help me set up the communication from Arduino to my computer? Or does anyone have experience with this and would be able to give me some tips?
It's relatively straightforward.
bind the arduino bluetooth to your mac bluetooth.
use Serial.* print commands. Normally these go to your computer via USB, but if you have the Bluetooth connected it will go over the Bluetooth connection.
the default baud rate of most bluetooth devices is 9600 baud.
So, develop your code the same way as if you were connected via Serial over USB, and it will work without change when you attach the Bluetooth.
Note: Typically USB and Bluetooth will use the same pins, so you can only use one or the other, not both at the same time.

On my machine lspci -v shows that my ethernet controller is using tg3. Can I use e1000e instead of tg3. Unloading tg3 module and the load e1000e module is not helping because the eth0 interface remains down after the e1000e is loaded. Please suggest if I am missing something.
Thanks.
No tg3 and e1000e are drivers for different models of ethernet card. If you want to use e1000e for some reason you'll need to buy a suitable intel Ethernet card.

Can someone tell me about RFID reader that is compatible with Beagle Board??
Anything that is Linux compatible over USB should work easily. The OpenBeacon looks interesting to me.
What type of RFID LF/HF/UHF? MiFare? The beagle board has a UART and supplies power, that should be enough for most embedded readers out there. You could also use a bluetooth shield and have even more flexible options.
Well if you are looking for a PICC's UID reading with a low-cost solution you should look here. It is a lightweight library written in C for BeagleBone Black.
You could use this library with RC522 Module. Communication protocol is SPI(SPI0) between BBB and RC522 Module.
