PPS configuration in Quectel L26-T module

IoT Modules GNSS Module
1

Hi,

I’m working on the Quectel L26-T GNSS module and I have few doubts regarding configuration of the same.
1/ Does the module (L26-T) support AT commands to obtain particular NMEA message sentences?
2/ Can I directly configure the PPS manager to generate PPS signals using PSTM commands or any other settings?
3/ Should I save and reset the module to retain the configuration in case of PSTMPPS commands?
4/ While configuring PPS manager should I disable the PPS and then configure?

Thanks

Hi，
Please refer to the following:

  1. AT commands are not supported. For NMEA sentence configuration commands, please refer to PSTMCFGMSGL.
  2. You can refer to “2.3.15. $PSTMPPS” chapter and examples.
  3. Yes.
  4. No need.

Best Regards

Hi,

After booting I’m getting continuous NMEA logs from L26-T module.
I’m not able to send PSTM commands for configuration from the same serial terminal.

Thanks

Hi，

  1. Please confirm whether the serial port RX is working normally. For example, sending “$PSTMGETPAR,1500” will return version information.

  2. Please provide the PMTK commands you sent and the corresponding log.

Best Regards

Hi,

I’m not able to type any commands in serial port since the log is continuously coming.

Thanks

Hi，
The continuous output of TX does not affect the input of RX.
Are you using the serial port tool on the PC?

Hi,

I’m using minicom in PC.

Hi，

Perhaps you can use the serial port tool of the Windows system to test it first.

Hi,

I’m able to get the GPS parameters using libgps API’s.
Is it possible to send the commands to gpsd using gps_send() API from libgps?
How should be the command format?
Does it support wire-protocol commands to be send to the gps deamon?

Thanks

Hi，
Sorry for the late reply.
No matter what method is used, as long as the module’s serial port can receive it.
For the command format, please refer to chapter 2.3 of the protocol document.

Best Regards
