Hello,
I try to interface this GPS board with my Raspi4 with serial converter.
First, 115200 bd doesn’t work, but 38400 bd is good.
I want to know where to find the data protocol specification, mainly to change the period of emission of the scan/transmission of data.
It seems to be 1 second by default.
Which is the frame to send ?
Best regards.
Not sure if ublox has a manual of commands, but if they don’t you could use their [u-center software to send configuration commands and see what the software is outputting then copy that on your Pi.
Another thing you could do is configure the GPS with u-center then save that to the module so that your new configuration is always used.](u-center)
Thank you.
I succeed to receive frame, and to change frequency by command.
I will verify later if new period is valid after disconnection.
If found in doc “NMEA Reference Manual-Rev2.1-Dec07.pdf” the following frame, but it seems not possible to set less than one second. Perhaps it is only possible by proprietary commands of u-blox.
Best regards.
