The GP1818MK GPS module produces messages at 1hz, is there command to send to the module that will increase the rate? The TX port on the module and similar produces is undocumented, is there documentation to what if any commands the modules will accept?
As sold, I don’t believe these accept any commands since the TX pin isn’t broken out. I’m not seeing anything in the data sheet that indicates these are configurable either but it may be possible if you can find a command list somewhere. It doesn’t look like sparkfun has a command list though.
