Is it a Quectel Tool?

Hi, I’m testing my LC29HDA by QGNSS 2.0.
Module receives and calculates some position data, however no information appear on the detailed views ( satellites, power, etc.monitors are completely empty). Can it be a firmware issue, or do I configure something wrong?

Can better use QGNSS_V2.2_EN | Quectel or set 2.0 properly…

You have only $GNGGA sentence in nmea output…
$PAIR062,-1*0E to return NMEA output to default settings; & $PQTMSAVEPAR*5A

for individual nmea

$PAIR003*39 → power off GNSS system
$PAIR062,1,0*3F  Disable GLL sentence.
$PAIR062,2,0*3C  Disable GSA sentence.
$PAIR062,3,0*3D  Disable GSV sentence
$PAIR062,4,0*3A   Disable RMC sentence.(Recommended Minimum Specific GNSS Sentence)
$PAIR062,5,0*3B ; Disable VTG sentence.
and 
$PAIR062,0,1*3F  **turn on** GGA nmea ,,, after to save:
$PQTMSAVEPAR*5A
$PAIR023*3B   reboot  module

Usually the lc29hda version is for default in rover mode…
However,checks and tries to execute this set of commands:
When executing commands, note the response and copy/paste for debug

$PAIR382,1*2E → Test command for lock system sleep enabled   
$PAIR003*39 → power off GNSS system  
$PAIR512*3C  clear data
$PAIR514*3A  Clear the current configuration and restore the default settings set via $PAIR
$PQTMRESTOREPAR*13   → Restores all parameters set via $PQTM
$PAIR023*3B   reboot  module
$PAIR003*39 → power off GNSS system 
$PQTMCFGRCVRMODE,R*32  ask result
if not in rover mode (1) do
$PQTMCFGRCVRMODE,W,1*2A         Set Rover mode
$PAIR063,-1*0F  ask for all nmea status: see pos. after -1 (all sequence with 1,1,1,1,1....)
if not do 
$PAIR062,-1*0E  Default enable all nmea
$PQTMSAVEPAR*5A   save file system
$PAIR511*3F    Save current navigation data from RTC RAM to flash
$PAIR513*3D  save file system
$PAIR023*3B   reboot  module
$PAIR007*3D → Full cold start will performs a cold start and clears system and user configurations,Restores all parameters  to factory settings.
