Hi,
I’m working on development of GPS asset tracker with BG96.
Using at+qgpsloc
command, it collects position information and post to server. Basically it works well.
Now I’m curious if it uses QZSS or not.
If I enable Beidou by gnssconfig command like AT+QGPSCFG="gnssconfig", 1
, does it already using QZSS also for positioning?
Or, do I need to do something special such as upload a specific firmware to enable QZSS for positioning?
In both BG96 GNSS AT commands manual
and BG96 GNSS Application Note
, I could not find description about how to enable QZSS for positioning.
Just for NMEA sentences, I found that QZSS sentences will be output along with Beidou sentences.
Best regards,
Takashi

Thanks for the answer.
I thought that the enable/disable of NMEA sentences is just about if the module output sentences when requested by AT+QGPSGNMEA
command, which is independent to AT+QGPSCFG="gnssconfig"
controlling which constellation to be used as a whole system.
Let me change my question.
Does BG96 use QZSS to get position by following commands?:
AT+QGPSCFG="gnssconfig",1 // GLONASS ON/BeiDou ON/Galileo ON
AT+QGPS=1 // Turn on GNSS.
~~ wait for fix ~~
AT+QGPSLOC? // Obtain positioning information.

Could you let me know the confirmation status?
Best regards,

I suppose whenever GPS is enabled, QZSS is also enabled.
However you need to check PRN number stated in the NMEA messages to see if any QZSS satellites have been used.
