GNSS Module Series GNSS SDK Commands Manual 1 Introduction Quectel GNSS modules support SDK commands which are defined and developed by Quectel. This document describes these SDK commands. The configuration parameters saved by SDK commands will still exist in flash even after upgrading the modules’ firmware. This document is applicable to Quectel L70, L80, L76, L76-L, L86 and L26 modules. Their supported SDK commands are shown in the table below: Table 1: Current Supported SDK Commands SDK Commands Description L70 L80 L76 L76-L L86 L26 PQBAUD Change NMEA Port Default Baud Rate PQEPE Enable/Disable PQEPE Sentence Output PQ1PPS PQFLP Set the Type and Pulse Width of 1PPS Output Set the Module into FLP (Fitness Low Power) Mode Y Y Y Y PQTXT Enable/Disable GPTXT Sentence Output N PQECEF Enable/Disable ECEFPOSVEL Sentence Output PQODO Start/Stop Odometer Reading PQPZ90 PQGLP PQVEL PQJAM PQRLM Enable/Disable Switching from WGS84 to PZ-90.11 Set the Module into GLP (GNSS Low Power) Mode Enable/Disable 3 Ways Velocity Sentence Output Enable/Disable Jamming Detection Function Enable/Disable Return Link Message Output PQGEO Configure Parameters of Geo-fence N N N N N N N Y Y Y Y Y Y N N N N N N N N Y Y Y N N Y Y Y Y Y Y Y Y Y Y Y N N Y Y Y Y Y Y Y Y Y Y Y Y Y Y N N Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y Y GNSS_SDK_Commands_Manual Confidential / Released 5 / 28 Quectel Confidential

GNSS Module Series GNSS SDK Commands Manual 2 Quectel NMEA Packet Protocol This chapter introduces the Quectel NMEA packet protocol which is a set of extension messages of the standard NMEA packet protocol. These messages are used to control and configure Quectel L70, L80, L76, L76-L, L86 and L26 modules. The structure of Quectel NMEA packet is shown as below: 2.1. Quectel NMEA Packet Format Preamble TalkerID PktType DataField * CHK1 CHK2 CR LF Packet Contents: Preamble: One byte character. ‘$’ TalkerID: Two bytes character string. “PQ“ PktType: 1-10 bytes character string. An identifier used to tell the decoder how to decode the packet. DataField: The DataFileld has variable lengths depending on the packet type. A command symbol ‘,’ must be inserted ahead of each data filed to help the decoder * : process the DataField. 1 byte character. The star symbol is used to mark the end of DataField. CHK1, CHK2: Two bytes character string. CHK1 and CHK2 are the check sum of the data between Preamble and ‘*’. CR, LF: Two bytes binary data. The two bytes are used to identify the end of a packet. NOTE The maximum length of each packet is restricted to 255 bytes. GNSS_SDK_Commands_Manual Confidential / Released 7 / 28 Quectel Confidential
