Thread: Problem with writing commands to GP-635T

Hi. I'm not a specialist in this area so I can be arbitrarily wrong, but I can google.
I've found that PSRF103 is a command for SIRF chips.

And if you search for "SIRF" word on the following page you would start thinking that maybe GP-635T is not SIRF based.

Also my intuition tells me that disabling some NMEA messages is not enough to increase the output rate and you should request the new baud rate by sending a specific command.
And, yes, 9600/5/8 = 240 is not enough for the NMEA message group if all NMEA messages are enabled.
My NMEA samples have ~400 chars per message group.
