# Commands Accepted by the Tracker 650 Here is a summary table of commands the Tracker 650 recognizes. Each message is described in further detail after the table. “Sticky” means the effect of the command is preserved across a power on/off cycle. Commands are terminated with a newline (ASCII 0x0A, C++ “\n”). Carriage returns (ASCII 0x0D, C++ “\r”), if any, prior to the newline are ignored. There are additional commands for factory use that are not documented. Try not to experiment, for example, we recommend not sending a “BRICK-DEVICE” command to see what will happen.
