I use the pistar on the raspberry with the dvmega as a hotspot, for over a year and everything works very well. I often use the private call oint to point to a friend who also uses a different hotspot than mine. Since I updated the pistar to the latest version I can no longer make the direct call; I listen to the friend who calls me but he doesn't listen to me. What may have happened? can someone help me?
