BluTuNode - Wireless sensor/actuator node software for Bluetooth modules

This is experimental firmware for CSR BlueCore based Bluetooth modules
allowing a host to control most of the I/O aspects of a module via wireless,
Bluetooth connection, thus allowing for low-cost, flexible, easily accessible
solutions for various remote control and automation tasks.

This software is released under the terms if GNU General Public License
version 3,


This application should be considered proof of concept and alpha stage. It did
not undergo sufficient testing or was used in production setups. If you are
intrested in this project, please consider testing it, reporting the issues,
and trying to fix them.


To build this software, you unfortunately need a propriatary XAP CPU toolchain
and library from CSR. Prebuilt application files are provided for convenience.
If you are interested in this project, please consider developing OpenSource
toolchain for XAP/BleuCore.


To flash this application into a BlueCore module, you need to combine it with
CSR Bluetooth stack firmware. You can extract such firmware from your module
or download it from CSR. This project cannot distribute stack firmware or
combined firmware image due to licensing restrictions. If you are interested
in this project, please consider developing OpenSource tools to read/write
module flash and combine firmware images.


Once module is programmed and powered on, on the host, as root:

1. Pair the module with your host - use whatever utilities you have and

2. Find out the Bluetooth address of the module:

# hcitool scan
Scanning ...
        xx:xx:xx:xx:xx:xx       linvor

"linvor" is common name in lowe-cost HC-04 modules, your module may have
another default name.

3. Create RFCOMM devic to communicated with the module:

# rfcomm bind /dev/rfcomm0 xx:xx:xx:xx:xx:xx

4. Connect to the BluTuNode software on the module:

# picocom -b 115200 /dev/rfcomm

There may be delay few seconds before "Terminal ready". Immediately after
connection, BluTuNode prints GPL notice.

5. At this point, BluTuNode is ready to accept commands, which by common
convention start with "AT" prefix (case is not important).

6. List and format of support commands can be found in file command_parse.parse
