Hi jyijyi,

We have a MangoH Yellow which uses WP7702.
Can we use it?
What would you suggest about it.

Thanks & Regards,
Pallavi.

i think you can try it …

Hi, how can I understand that the board is connecting to the supl server, I have set up a proxy GitHub - tajuma/supl, but I can’t see the requests.
at what time is the board connected to the supl server? after cold start?
is there a way to debug?

24

how about for indoor environment and not connecting GPS antenna and see if you can get gps fix?
SUPL should be working inside indoor environment

25

So do not connect the gps antenna?
and set the msBase mode?

and quotes bother me? where should they be placed? after the port or before? if yes then i get error

I believe you need to use “MS-assisted only” mode in AT!GPSfix.
Have you tried to put the port number inside the quotes?

27

yes, i tied., got ok. But line “is not checked for correctness”

28

gnss set agpsMode msAssist
gnss restart cold
gnss get loc2d

can i use cat/dev/nmea?

29

how about using AT!GPSFIX?
you should see something in /dev/nmea

30

AT!GPSFIX?
got
error

31

at!gpsend=0
OK
at!gpsfix=?
!GPSFIX: ,,
: 1-Standalone, 2-MS-Based, 3-MS-Assisted
: 1-255 seconds
: 1-4294967280 meters

OK
at!gpsfix=1,255,10000
OK

32

at!gpsfix=1,255,10000 it’s for standalone.
for checking a-gps, i should use
at!gpsfix=3,255,10000
yes?

33

yes, you should use "MS-assisted only”

34

so, supl connection doesn’t work. because i don’t see any request to me proxy,
data connection is enabled, i can ping server, gnss get loc3d, recieve some location, with bad accuracy.
AT!GPSCOLDSTART return me error 18.

35

did you setup the profile 1’s APN in AT+CGDCONT?

36

AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“ip.primetel”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0

cm data

APN: ip.primetel

Dns1[IPv4]: 194.154.128.2
Dns2[IPv4]: 217.27.32.196

yes, inertnet is up.
i can ping 8.8.8.8 and supl-proxy

Manufacturer: Sierra Wireless, Incorporated

OK

37

how about using the following?

at!gpslbsapn=1,0x1f,“IPV4”,“ip.primetel”
AT!GPSfix=2,255,255

38

i entered these commands
after that gnss disable
gnss stop

gnss enable
gnss start
gnss get loc2d
and wait response on the supl-proxy.
doesn’t work.
maybe I’m forgetting something?

39

There is no need to enter gnss commands, you can use AT commands only

40

at what moment the module sends a signal to the supl server?
Is there any way to simulate manully?
