How can I change the output frequency of NMEA messages? I need the GPGGA message to output at 5Hz instead of the default 1Hz.
Hello! You can easily adjust the output frequency of any NMEA message using the LOG command via the serial port.
To output a message at a specific interval, you define the time in seconds. For 5Hz, the interval is 0.2 seconds (1 second / 5). For example, to output the GPGGA message on COM1 at 5Hz, you would send: LOG COM1 GPGGA ONTIME 0.2
If you want to change it back to the default 1Hz, you would simply send: LOG COM1 GPGGA ONTIME 1
That's very straightforward. Is there a maximum frequency limit I should be aware of for modules like the K803 or K827?
Yes, excellent question. The maximum output frequency depends on the specific module you are using. For instance, the K803 supports a maximum output rate of 20Hz, while the K902 can go up to 50Hz.
