Hello,
I have L89H gps breakout board , I want to change the update rate from 1Hz to 10Hz.
Can someone guide me how to change it?
Thank you.

Hi C_Vishnu
The default baud rate of L89H is 9600bps. If you want to change the NMEA output frequency to 10Hz, you need to change the baud rate to 115200bps first.
The instructions are as follows:

  1. $PAIR864,0,0,115200*1B //Set the baud rate to 115200bps
  2. Restart the module //L89H baud rate changes to 115200bps
  3. $PAIR050,100*22 //Set the NMEA output frequency to 10HZ
  4. $PAIR513*3D //Save configuration

Hello Mr.George,
Thank you very much for your quick reply.
Do I need to send these commands just via UART and is there anything to be done to put the module in like configuration mode or just have to send it .
Thank you
Best regards,

Hi C_Vishnu
Steps 1, 3 and 4 can be sent via UART. Step 2 simply power off the module and then power it back on.

Hello Mr.George,
I was able to successfully change the baudrate ,set the output to 10Hz but after reboot the output changed to 1Hz at baudrate of 115200bps.
Can you help me with this issue.
Thank you
Best regards,

Hi @C_Vishnu
I am so sorry. Please execute the following command to save it.

  1. $PAIR050,100*22 //Set the NMEA output frequency to 10HZ
  2. $PAIR382,1*2E //Lock system sleep
  3. $PAIR003*39 //power off
  4. $PAIR513*3D //保存指令
  5. $PAIR002*38 //power on

Hello Mr.George ,
No worries, I have executed the commands from step 1 -5 and the NMEA output rate is successfully changed to 10Hz and I have even tested after reboot everything is fine . Thank you very much for quick support and reply.
Thank you
