PPS signal


I have a HL8548-G but I am not able to get the PPS signal from my module.
I receive $GNGNS frames, so I think GNSS is working.
What do we have to do to enable it?


As per HL8548-G PTS(REV11_1) :-

“The PPS signal will only provide a pulse output once GNSS acquisition reaches sufficient accuracy to provide a reliable period. Specifically, this signal requires a GNSS fix to be obtained. Otherwise, no signal will be output at the PPS pin.”

It means PPS signal requires a GNSS fix to get activated.

Thanks & Regards,
