I have two Reach RTK GNSS modules that I am planning on using for robotic autonomous waypoint navigation. One robot will act as a base station while the other is a rover. I have been able to connect the sensors using the micro USB and setting a serial communication with a ROS package to convert the NMEA format to standard ROS sensor topics. However, the most recent update v2.18.0 caused the lsusb and ls /dev port name to vanish. The module showed up as a ttyACM port now no new port appears. Does anyone know of a fix to this problem?
My second question is how to get corrected values if the sensors are connected over serial. The input corrected values is in a different format RTCM3, and I would like to use the robots own network. I am unfamiliar with the RTCM3 format. Can I send that message format over serial to the network of the second robot back to serial again? How do the modules actually communicate for the corrected GPS values?
