NAME
nxtrc - a program to interact with LEGO NXT via BlueToothSYNOPSIS
nxtrc [-s]nxtrc [-a ADDR] [-v] command
DESCRIPTION
NXTRC (NXT Remote Command) is a small program that allows to send various commands to a LEGO Mindstorm NXT Brick. It uses the Bluetooth protocol through the Bluez libraries.The option -s starts a scan to find BlueTooth devices. If a BT address is given in the command line or is in the Environment Variable BTADDR it connects to the NXT and performs the task specified in <command>. The first time you connect with a device you need to exchange a password, this task is usually done by the Operative System BlueTooth Management (as Kbluetooth under KDE).
COMMANDS and OPTIONS
- -a
- BlueTooth Address of the NXT, required if BTADDR Environment Variable is not set to the address
- -b
- Get Battery Level
- -d FILE
- Delete FILE frome NXT
- -h
- display a short help text
- -i
- Get info on NXT brick
- -k
- Stop a program running on NXT
- -l[PATT]
- List files on NXT brick matching PATTern if present (e.g. -l*.rxe) N.B. No spaces between -l and PATT! see at the end the patterns allowed
- -m FILE
- Play sound file FILE once
- -M FILE
- Play sound file FILE indefinitely
- -n NAME
- Set NXT name to NAME
- -p FILE
- Run Program FILE on NXT
- -r FILE

- -v
- Be verbose. This is the only option that can be given with another command. It's not always very useful....
- -w FILE

File Names and Patterns
On the NXT File names are of the form "Name.Ext" with max 15 characters for the Name and 3 for the Extension. When asking a listing with the -l command you can give a specific file name to see if it's on the NXT and list its size, or a Pattern using widlcards. Due to the limitation of the NXT API patterns are limited to the form "*.ext", "Name.*" or "*.*" this last one is the default and can be omitted.
EXAMPLES
scan for devices$ nxtrc -s
00:10:20:30:40:50 NXT1
00:01:01:02:03:04 NXT2
set up Environment Variable for connection with NXT1 and ask for info
$ export BTADDR=00:10:20:30:40:50
$ nxtrc -i
load program Prog.rxe on NXT1 and run it
$ nxtrc -W Prog.rxe
$ nxtrc -p Prog.rxe
