Tmote Connect Advanced Operations

This section describes the Tmote Connect control protocol for expert users. The protocol has

been engineered for simplicity and readability rather than compatibility with existing standards

(like HTTP) or security. All protocol transactions take a form of

Command line

Optional data

Optional trailer

After issuing the command, the client reads the response from the socket until the server closes

the connection. The examples below use nc (netcat) utility to show protocols in action.

Currently, the following protocol actions are supported:

status

quit

msp430-bsl

baudrate

protocol

unfriendly_system_reboot

Status

Various status parameters of the Tmote Connect

control server can be obtained by connecting to

the Control port and issuing a single line with the

word “status”. The server returns a sequence

key value pairs, each on a separate line. Keys

are limited to be a single word, the value begins

after the initial space and extends until the end

of the line. For example, to access the status of

the server at IP address 192.168.4.104

connected to the mote on port 2, we could

execute the following command

echo status | nc 192.168.4.104 10002

Programming Protocol

Tmote Connect’s programming protocol is based on msp430-bsl application. The command

can be issued in the form:

echo “msp430-bsl <command-line-switches>” | nc 192.168.4.104 10002

Command line switches specify the device type to be accessed and a sequence of actions to

perform. When a program is being uploaded to the mote, the above command is to be

immediately followed by the program image in the IHEX format. The end-of-file is signified via a

blank line. The server responds with a sequence of diagnostic messages that one see as an

output from msp430-bsl.
