HL8548 - GPSCONF for GPS/GLONASS/SBAS/QZSS

The datasheet says that the value “2” is default. However, I readback GPSCONF and it gives 1. When I try 2 it throws an ERROR. Is it possible to get the extra systems?

This is on 5.5.23 version of the HL8548 firmware.

Little light on detail here, are you talking about setting GPSCONF to use GPS and GLONASS vs just GPS? If so do you mean the command

at+gpsconf=10,1

is failing (even though this is the default)?

Hello Matt,

Yes, I was trying to set what the “default” value in the datasheet for GPSCONF as you described:

AT+GPSCONF=10,1

Rob,

Just tried it with 5.5.24 and it seems to work ok.
