at+gpsconf=10,2 to enable GPS/GLONASS/SBAS/QZSS mode.
Then I run
at+gpsnmea=1,,15 to get all available NMEA sentences.
Among them, I saw sentences
$QZGSV,1,1,,,,,,,,,,,,,0.0*4B which seems to show that no QZSS satellites were found. However, according to the manual, QZGSV sentence is not supoprted in HL8548-G.
Despite this, does this still mean my device is not receiving the signal from QZSS?
How to know if it receives signal from QZSS?
HL8548-G supported the QZSS since FW v18.104.22.168.201612281616.x6250_1.
Here is some NEMA output from HL8548G:
Thanks. Did you just set
at+gpsconf=10,2 and it worked?
yes. need to set at+gpsconf=10,2` to enable GPS/GLONASS/SBAS/QZSS mode.
Make sure FW > v22.214.171.124.201612281616.x6250_1.
i c. I will try again.
By the way does SBAS work for you?
SBAS is part of the standard software provided by CSR.
SBAS should can work fine as well.
Suggest use GPS simulator to check.
