Loading Extended Ephemeris on WP7702

IoT Modules
21

I try with AT commands but Xtra Data status always equal Unknown
LoadEphemeris file doesn’t change, AT!GPSXTRAINITDNLD doesn’t change

AT!GPSXTRASTATUS?
Xtra Time status   = Valid
Xtra Data status   = Unknown
Validity Start = 2025 06 26 3 04:00:00
Validity End   = 2025 07 03 3 04:00:00

I think if data status equal valid, xtra injection is working?
How can I make data status = valid?

I don’t see issue with WP76 module:

Still data status=unknown

How can I try with SUPL instead?

your module seems to have problem to download data.

For testing in SUPL, you need to find SUPL server first

25

If I try supl.google.com for SUPL server, what certificate do I need or can I try without certificate

26

i don’t quite see any command for entering the certificate.

BTW, I am still not sure if your module has data connection problem, have you verified if your module can download the following?
http://xtra1.gpsonextra.net/xtra.bin

27

Here can inject supl certificate?
le_gnss_InjectSuplCertificate()

Module can download using http://xtra1.gpsonextra.net/xtra.bin wget command?
Or you mean download another way?

28

yes, you can try first with wget

29

I have no data issue I can download files and access internet

30

then i have no idea why it shows unknown in AT!GPSXTRASTATUS?.. especially i don’t see such issue on my side.

31

What version of legato are you using? What firmware? Maybe carrier firmware is issue
