Activating the L26-P function

IoT Modules GNSS Module

Good afternoon! Please write what commands activate NMEA messages: GSA; GSV; GLL; GBS; GNS; GST; ZDA.

Hi，
Please refer to the $PSTMCFGMSGL command in the attached protocol document.

Hi，
Please help provide the L26P firmware version, which can be queried through $PSTMGETPAR,1500.
In addition, when opening these statements, please pay attention to the amount of output data and whether the current baud rate can be met.

Best Regards

Good afternoon! I’ve been looking at these specs. I am not an engineer and the logic of these commands is not entirely clear. Check that the commands you enter are correct:

ON $–GSA message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x4
$PSTMSAVEPAR
$PSTMSRR

ON $–GGA message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x2
$PSTMSAVEPAR
$PSTMSRR

ON $–GST message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x8
$PSTMSAVEPAR
$PSTMSRR

ON $–GNS message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x1
$PSTMSAVEPAR
$PSTMSRR

ON $–RMS message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x40
$PSTMSAVEPAR
$PSTMSRR

ON $–GSV message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x80000
$PSTMSAVEPAR
$PSTMSRR

ON $–ZDA message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x1000000
$PSTMSAVEPAR
$PSTMSRR

ON $–GLL message*

$PSTMGETPAR,1201
$PSTMSETPAR,1201,0x100000
$PSTMSAVEPAR
$PSTMSRR

Hi，

It cannot be configured like this.
Please refer to this method in the following picture, first read the current parameters, and then write the required statement parameters after calculation.

Best Regards

I wrote that this guide is incomprehensible to me. Where did this 0х00180056 figure come from? Can I just ask you to fix my commands?

8

Hi，
0х00180056 is the current configuration of the module returned after querying the $PSTMGETPAR,1201 command.
You need to provide the current firmware version, so that I can provide you with the corresponding commands. These default parameters are different for different versions, so I asked you to provide version information before.

Best Regards

What program can I use to send a version request? I updated the module with the firmware L26PNR01A02_QX_BOOT.bin. Can this help?

10

is this what you need?:
$$PSTMDRSENCONFIG,IMU GYRO,LSM6DSR,125,4375,52,26.0,13E
$$PSTMDRSENCONFIG,IMU ACC,LSM6DSR,2,61,52,26.067
$$PSTMCFG,LMS,1,0,0,50.0,50.0,05,03,60.0,0.000000,0.000000,-2.671600*12

11

L26PNR01A02_QX is the firmware version. I will confirm the commands before replying.

Best Regards

Hi，
By default, GGA and RMC are enabled.
The command to enable GSA+GST+GNS+GSV+ZDA+GLL is as follows:
$PSTMCFGMSGL,0,1,01B8034F,00000000
$PSTMSAVEPAR
$PSTMSRR

Please refer to the attached document for the specific configuration method.

What NMEA messages do I need to connect to work in RTK mode?
Please tell me where to download the program rinex_tools.exe to convert raw data from the receiver to the RINEX format?
What commands can I use to switch between NMEA and RTCM?

20

Hi，

1.The realization of RTK requires an external algorithm to parse the satellite raw data of NMEA sentences (PSTMTG and PSTMTS sentences).
2.I don’t have the program rinex_tools.exe you mentioned. Where did you see this tool.
3.I need to confirm before replying.

Best Regards

21

Good afternoon! How to connect these PSTMTG and PSTMTS offers?

22

Hi，
PSTMTG and PSTMTS are enabled by default.
The external master control obtains the PSTMTG and PSTMTS statements through the serial port, and then parses the required information according to the definition of the protocol document, so as to perform the RTK calculation of the algorithm.

Best Regards

23

Good afternoon. I looked through Teseo_Suite_Pro, there are only PSTMTG messages. PSTMTS do not go.

24

The base station does not see the coordinates of the rover and does not send it corrections

25

Hi，
PSTMTS is turned on by default. Is this statement not output through the serial port of the module at present?

Please provide screenshots or serial log.

Best Regards

26

Hi，

I don’t quite understand what is meant here?
The output of L26P is the original observation and measurement of the satellite, which requires an external host algorithm to implement RTK.

Best Regards
