We are a group of students that have an assignment for a customer, to make a system that contains of five NV08C-RTK GPS- receivers, where one is a Base station and the other four are Rovers. We are using Xbee pro s2 to communicate between the units. The Base station will receive NMEA signal from the different Rover`s, and send back RTCM correction signals. We need to have an address for each Rover the NMEA signal is coming from, this is to separate between them, and know who is who.
We have try to use API mode whit some luck, but we was unable to send correction signals back to the Rover`s. We need some help whit the API mode, and we are a little short of time.
Is this possible to use API mode, or do we need to use micro controllers.
