+=head1 NAME
+
+net-mqtt-sub - Perl script for subscribing to an MQTT topic
+
+=head1 VERSION
+
+version 1.143260
+
+=head1 SYNOPSIS
+
+ net-mqtt-sub [options] topic1 [topic2] [topic3] ...
+
+=head1 DESCRIPTION
+
+This script subscribes to one or more MQTT topics and prints any
+messages that it receives to stdout.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-help>
+
+Print a brief help message.
+
+=item B<-man>
+
+Print the manual page.
+
+=item B<-host>
+
+The host running the MQTT service. The default is C<127.0.0.1>.
+
+=item B<-port>
+
+The port of the running MQTT service. The default is 1883.
+
+=item B<-client-id>
+
+The client id to use in the connect message. The default is
+'NetMQTTpm' followed by the process id of the process.
+
+=item B<-verbose>
+
+Include more verbose output. Without this option the script only
+outputs errors and received messages one per line in the form:
+
+ topic message
+
+With one B<-verbose> options, publish messages are printed in a form
+of a summary of the header fields and the payload in hex dump and text
+form.
+
+With two B<-verbose> options, summaries are printed for all messages
+sent and received.
+
+With three B<-verbose> options, a hex dump of all data transmitted and
+received is printed.
+
+=item B<-keepalive NNN>
+
+The keep alive timer value. Defaults to 120 seconds. For simplicity,
+it is also currently used as the connection/subscription timeout.
+
+=item B<-count NNN>
+
+Read the specificed number of MQTT messages and then exit. Default
+is 0 - read forever.
+
+=item B<-one> or B<-1>
+
+Short for B<-count 1>. Read one message and exit.

+0x00 Seq # DWord(4) R / 0 The platform can carry the ID when the platform downstream reads and sets the device parameters, and the device returns the same data. Please refer to the example for use.Each seq # refer to one command and its response.
+0x01 PN DWord(4) R / / /
+0x02 Model Byte(1) R 32 32 Inner number:32
+0x03 X axis angle Float(4) R ‐90°~90° / X axis angle
+0x04 Y axis angle Float(4) R ‐90°~90° / Y axis angle
+0x09 X axis relative angle Float(4) R ‐90°~90° 0 Return the X angle value according to the set relative zero
+0x0A Y axis relative angle Float(4) R ‐90°~90° 0 Return the Y angle value according to the set relative zero
+0x0C Sensor temperature Word(2) R ‐32768~32767 / signed,sensor temperature =Data/100, unit ℃

+0x11 Arming/disarming Byte(1) R/W 0~255 1 0 means disarming, non‐zero means arming
+0x12 Alarm delay time Byte(1) R/W 3~255 20 The unit is 0.1 second, which means that the product responds to the alarm only after the alarm has exceeded the alarm angle for a certain period of time.
+
+0x13 Restore factory setting Byte(1) R/W 0~255 0 0: Do nothing Non‐zero: Restore the non‐network‐related parameters of the sensor.
+0x14 Server IP&port 4*Byte(1)+Word(2) R/W / CTIOT:117.60.157.137,5683 MQTT:0.0.0.0,0 The server address should be IP, not the domain name; using the domain name may cause the connection server to be unstable and cause data loss.
+0x17 Signal strength Byte(1) R 10~34 / A larger value indicates a stronger signal
+0x18 Sensor operating mode Byte(1) R/W 0 0 The sensor can only work in absolute measurement mode
+0x19 Alarm axis Byte(1) R 0~ 3 / 0: no alarm; 1: X‐axis alarm 2: Y axis alarm; 3: X/Y axis alarm at the same time
+0x1A SIM card ID QWord(8) R 0~18446744073709551615 / Take the first 19 digits, the last digit is discarded
+0x21 Heartbeat interval DWord(4) R/W 60~131071 86400 Interval at which the device periodically uploads data to the server
+0x22 IMEI number of the device QWord(8) R 0~18446744073709551615 / Refers to the IMEI of the NB‐IOT network module in the product.
