I downloaded the Firmware 31 (reach-rs2-v31.0-r3) and I installed it using the Reach Firmware Flash Tool 1.9.2. in my RS2.
When I started with the Base configuration, on GNSS Settings, there is not Positioning Mode available and I could not select between Static or Kinematic mode.
I did the installation procedure again and the result was the same the Positioning Mode is missing.
Before Firmware 31, I was installed 30.1 and it worked well.
Someone has the same problem with RS2?
