Applications / Libraries

ConnMan

Daemon for managing Internet connections within embedded device and integrates a vast range of communication features usually split between many daemons such as DHCP, DNS and NTP. The result of this consolidation is low memory consumption with a fast, coherent, synchronized reaction to changing network conditions. ConnMan Homepage

RFKill

A small userspace tool to query the state of the rfkill switches, buttons and subsystem interfaces. Some devices come with a hard switch that lets you kill different types of RF radios: 802.11 / Bluetooth / NFC / UWB / WAN / WIMAX / FM. Some times these buttons may kill more than one RF type. The Linux kernel rfkill subsystem exposes these hardware buttons and lets userspace query its status and set its status through a /dev/rfkill. Given that at times some RF devices do not have hardware rfkill buttons rfkill the Linux kernel also exposes software rfkill capabilities that allows userspace to mimic a hardware rfkill event and turn on or off RF.

Libraries

For C Bluetooth Development:

For Python Bluetooth Development:

For Python Bluetooth in Edison (using pip, if for some reason you don't have it, learn How-To Install Pip):

There are two common ways to test SPP, one is by using D-BUS, the other is by using RFCOMM transport protocol.

To test using D-Bus we can use this python script, copy it to Edison, enable the bluetooth device and run it:

Then in an android device install a Bluetooth SPP Manager.

At this point you need to pair the Intel Edison with your android device (see example above on how to use bluetoothctl, hcicontrol or any other user level application in your Edison).

Once paired, open the Bluetooth SPP Manager app, hit search, and when the Intel Edison appears tap on in to connect. now you can send text messages to Edison which can be seen on the terminal window of the Edison.

I know this need a lil' bit further explanation. just dropped here so i won't forget. Also what is going to be added is how to programmatically do the device discovering, pairing and SPP using c and python
