Hello, I have the problem in my rtk express that it does not launch the configuration network to be able to change values that I want, in this case to be able to use it with survey master, I know that there is an option to do it by computer but I need to have the facility to do it by Wifi
What version of firmware is on the RTK device?
Can you see the RTK Config network from your phone?
What happens when you attempt to connect to RTK Config, then 192.168.4.1?
THE DEVICE DOES NOT LAUNCH THE NETWORK, I HAVE CHECKED IF IT IS MY CELL PHONE, BUT NO OTHER MOBILE DEVICE OR COMPUTER DETECTS THE NETWORK RTK CONFIG 
IT HAS THE V_3.6
