Configure UPDATE Rate on adafruit gps breakout

by luckyodisetti on Fri Nov 24, 2017 6:00 am

Using the Adafruit gps breakout board with raspberry pi. Interfacing directly with the ttyUSB0 using python Serial interface or gpsd both give update data only 1 per second. The update rate says 10hz so im assuming i should get close to 10 updates per second. Am i missing some configuration ?

In the downloads section, there is a command sheet for the module and you need to set the baud rate high enough to allow the update rate first or the command will be ignored.

I am using a raspberry pi so cannot make use of the arduino library that is available.

However i did try the following on the terminal and i still get only 1 update per second

//setting baudrate
>echo $PMTK251,57600*2C > /dev/ttyUSB0

//setting update rate to 100 milliseconds
>echo $PTK220,100*2F > /dev/ttyUSB0

No Lucky, it continues to only send at 1 per second. Appreciate the help!
