Ben's notes

See the following documentation for more information:

• Huawei MU609 miniPCIe Hardware guide.
• Huawei MU609 miniPCIe AT command spec.
• Huawei MU609 miniPCIe Application guide.

• ttyUSB0: MODEM port: simulated using USB, for AT command interaction and establishing data connection.
• ttyUSB1: DIAG port: simulated using USB, for DIAG (diagnostic) command interaction (mainly used to debug modules at present).
• ttyUSB2: PCUI port: simulated using USB, for AT command interaction only.
• ttyUSB3: GPS NMEA port: simulated using USB, sending unsolicited indications for NMEA positioning data only.
• ttyUSB4: GPS Control port: simulated using USB, for GPS AT command interaction only.
• eth3: ECM port: for establishing communication connection.

• Set the positioning method to Standalone.

  AT^WPDOM=0

• Set the session type to single positioning.

  AT^WPDST=0

• Set the session type to tracking and positioning.

  AT^WPDST=1

• Set the number of positioning times and the interval between each positioning for the tracking and positioning. If the session is a single positioning, you do not need to set these parameters.

  AT^WPDFR=65535,1

• Set the positioning service quality. The first parameter indicates the response time, and the second indicates the horizontal accuracy threshold.

  AT^WPQOS=255,500

• Start positioning.

  AT^WPDGP

• Present the positioning result.

  ^POSITION: 113.94026d,22.53206d,270m

• The first value indicates positioning end reason, and the second indicates the left positioning times.

  ^POSEND: -1,9

• Stop positioning.
