COMMANDs
Following are Commands to control and set various operating modes of the HP-01
Magnetometer, that can be distinguished in two main categories:
•
Query Commands: ?
•
Setting Commands: S
The commands have this format:
#H1Qcommand(parameters)* where:
# = command string start
H1 = header string always present (model identifier)
Q = ? for query commands
S for setting commands
Command = command string
(parameters) = setting parameters value (where present)
* = command string end
All commands, except for #H1?SPC* , produce a reply which contains the
command itself.
Example:
#H1?SPA* Reply: SPA=0 .
In the case of an unrecognized command (available commands are ? and S ),
HP-01 replies with Command ERROR.
Example : #H1&SPA* Reply: Command ERROR
In the case of a wrong command field, HP-01 replies with the received command
followed by
ERROR string .
Example : #H1?SIPA* Reply: SIPA ERROR.
