Hopefully someone else has had this problem and can give me some advice. I currently have the Venus GPS module with SMA connector and I love it. I can get fixes within 30 secs and I am able to change almost all the settings via the binary commands. However, I am not able to change the update rate which is the most crucial for my purposes.
When the command to change the update rate is sent I get a positive acknowledgment but nothing changes and I still get NMEA messages at 1 Hz. Like I said, I can change baud rate, adjust it so that I only get the $GPRMC messages (all I need), and even adjust the $GPRMC message update rate as long as it is less that 1 Hz (i.e. set the interval to 1 or greater seconds). Here is the message I am sending:
Any ideas on what to try? Are the binary codes for changing the update rate correct in the documentation? I send the binary message from the documentation to enable WAAS but never get a positive ACK. I'm at a loss for what to do now. Thanks in advance for the help!!!

Code: Select all
The above code is to set it to 2Hz but that does not even work. I get the positive ACK but no change in the actual update rate. I have tried the other update rates with no luck as well. Also, before I send these I change the baud to 115200.A0 A1 00 03 0E 02 01 0D 0D 0A
