Description of SinoGNSS K8-series GNSS Modules Common Commands

Upon receiving any GNSS modules/GPS modules for the first time, it's natural to want to verify certain essential information. To assist you with SinoGNSS K8-series GNSS modules in this process, We've compiled a list of frequently used checking commands that we'd like to share with you today.

Such as Log version/loglist/comconfig...

What do these instructions entail in terms of details? Let's delve into the specifics.

Begin by connecting our board and powering it on. Press the power button, and the software will promptly exhibit power-on information. For instance,

1. “LOG VERSION”

 log version // Check the receiver board type, SN serial number, firmware version, FPGA version, BOOT version and other information.

2.“LOG LOGLIST”

log loglist // view the command information currently set by the receiver/board

3.”LOG COMCONFIG/COMCONFIGA/COMCONFIGB”

The content of ”LOG COMCONFIG/COMCONFIGA/COMCONFIGB” is the same, but they are different information formats.

➤ log comconfig // Check the serial port status and baud rate setting of the receiver/board.

The meanings of the numbers in the two columns of RxType/TxType are:

"1": Any setting of the port can input and output commands normally;

"27": Set as RTK differential port, unable to receive commands.

➤ log comconfiga // Describe the configuration of the serial port, such as baud rate, COM ID, etc.

✔ “#COMCONFIGA,COM1,0,60.0,UNKNOWN,1930,000416.550,00000000,0000,1114” // COMCONFIG Header ;

✔ “*df1d6a86” // 32-bit CRC check (only available for ASCII and binary)

➤ log comconfigb

There are three ways to express the data on the board: Simplified ASCII, ASCII, and Binary. All commands and messages can be expressed in any one of the three formats. In addition, ComNav boards also support RTCM2.X, RTCM3.X, RTCM, CMR, and NMEA format messages. The number of bytes of binary data is minimal.

4.“LOG SYSCONFIG”

 log sysconfig // Check basic configuration, rtk configuration and work mode like PPS, Event, and SBAS.

6.”UNLOGALL”

 Unlogall // cancel the output of specific serial port messages. If no serial port is specified, the message output of all serial ports will be stopped.

If the serial port is specified, the message output of the specified serial port will be stopped. For example,

unlogall com1  // then the output of serial port 1 will stop.
