hi,

I am unable to get 10 times a second gps reading with onion gps expansion.

i have tried to set 115200 baud rate as below , and nothing works.. i still get readings only 1 time per second
A. using my windows pc and ucenter.. (following this https://hackaday.io/project/167456-gps-receiver-configuration-and-comparison/log/168192-configuring-the-10hz-gps-receivers)

B. using ubuntu on jetson nano using 'stty -F /dev/ttyACM0 921600' and i have tried using cat on command line, python code and a c code with gpsd.

Can you please help.. if the product cannot perform 10 times a second.

Thanks.

@Manu-Yareshimi The baud rate just sets the communication speed between the Omega and the GPS Expansion. This is unrelated to the number of GPS readings per second.

I've never tried getting readings any faster than the default, but it looks like you will need to configure the GPS Expansion using AT commands to change the number of readings per second. I believe this is mentioned in the article you posted.

It's also possible gpsd may not be able to keep up with faster readings. But let us know how it goes!
