Dexter Industries dGPS Sensor

Recommended Posts

The Dexter Industries dGPS sensor manual has a reference to use I2C commands to turn on and turn off extended firmware functions that provide HDOP, altitude and number-of-satellites data. The manual also states that these extended functions can slow down dGPS processing.

I am seeing some long delays in updating distance-to-waypoint data from the navigation block used with the sensor. I would like to turn off the extended firmware functions temporarily to see if the distance data gets updated quicker. However, I don’t know how to send I2C commands to the dGPS via the NXT-G configuration software, or if it’s even possible.

I would appreciate any guidance I can get on how to send I2C register change commands to the dGPS sensor.
