L26-DR (U): How to configure a higher message rate?

IoT Modules GNSS Module
1

Dear Quectel forum team,

we are currently testing/evaluating the “L26-DR (U)”. In the document “Quectel_L26-DR_GNSS_Specification_V1.3-4.pdf” it is stated, that the UDR version of the module supports output rates up to 10Hz.
However I’m searching for the correct command to configure a higher output rate of the NMEA messages?
For this I have the document “Quectel_L26-DR_GNSS_Protocol_Specification_V1.1_Preliminary_20200630.pdf” available.

At first I thought, that this could be done with the “rate” parameter of the “$PSTMCFGMSGL” command. However if I set this parameter to 5 (for 5Hz) the module acknowledges this command and then just restarts without changing the output rate.

The module firmware: PSTMSETPAR,1500,L26UDRNR01A04V02_SCY

Best regards

Dear Sir
Please refer to the following commands.

1hz：

$PSTMCFGMSGL,0,1,0088004F,4F000000

$PSTMSAVEPAR

$PSTMSRR

5hz：

$PSTMCFGMSGL,0,1,0088004F,4F400000

$PSTMSAVEPAR

$PSTMSRR

10hz：

$PSTMCFGMSGL,0,1,0088004F,4F800000

$PSTMSAVEPAR

$PSTMSRR
Note: It is best to set the baud rate to 230400 for 10Hz.

Best Regards

Thank you very much!
The commands work as intended.

May I ask if the Quectel_L26-DR_GNSS_Protocol_Specification_V1.1_Preliminary_20200630.pdf will receive an update and be officially downloadable from quectel.com in the near future? Currently I do not find any corresponding documentation there:
