Not able to connect on x-t5

[kendarorg]

Trying to connect to an x-t5 (latest fw) but no luck, apparently it is not able to connect. There is a weird thing about that, the xt-5 does not allow the AP mode, but starts only a temporary AP when called by the bluetooth application when in "standard mode" (that i tried to replicate in java starting from https://github.com/gkoh/furble but with no luck... because the notification on the "configuration" gatt does not arrive, but this is another thing)
I tried to intercept the protocol used to communicate via tether app (through wireshark) but i have not found anything really interesting.
I even tried to connect with tether but the ports are closed (and a port scan gives no luck at all)
Some suggestion (or i am doing something really wrong in your opinion?)

ok when starting t5 in wifi tether, the fuji tether app sends first an udp message to find the port and init the connection changing the wifi icon from red to yellow when the handshake is completed, handshake made with a "http like" fashion
