After the HEG worked properly with my MacBook and Chrome I've changed to bluetooth-connection to work with my Android, but it doesn't work. Than I liked to return to Wifi, but now I can't see My_HEG in Wifi-connection. Red light of Alpha-HEG is shinning, but I can't reach. After sending the command 'b' or 'B' twice via the correct COM port there is no Wifi- nor BT-connection to the HEG Alpha in my MacBook. What can I do?
