I just updated my antennas (Reach RS) to v2.18.1 and in the Base Mode function it does not stop transmitting corrections to the rover, the tab is “Off”.
The only way to cut the corrections is by changing to another type of correction.
After updating my antennas I connected them through Ntrip, there were no problems.
When I turned off the ntrip corrections on my Base antenna, my rover antenna still received them. The same happened with LoRa corrections, when I turned off the “base mode” box on my base antenna, my rover antenna was still receiving corrections.
