I add these useful commands for module debugging:
$PAIR003*39
disable gnss so output in terminal is blanc for read only command response
$PAIR002*38
enable gnss
I use sscom with a partial english translatet gui: 445.5 KB folder on MEGA or http://www.daxia.com/download/sscom.rar
as have difficult to send commands by Qgnss.
