Did you finally found how to send GPS data to your host over the http post? I'm trying to achieve the same thing, however...

I'm starting to test this with a Thingy:91 so I was looking for some example here to test it

Dear Håkon Alseth

Thanks for your support,

I was confusing about nb-iot connectivity in at_client also, so I tried to show you the report, i hope you can help 🙂

When I tried to enable nb-iot: %XSYSTEMMODE: 0,1,0,0

and I check the network:

AT+COPS?

+COPS:0

AT+COPS=?

+COPS: (1,"","","24201",9),(1,"","","24202",9)

OK


I see: NB-IoT is connected, but


LTE & PDN 
and 
Show serving station location: NOt availbe 

Is it correct?

Thanks,

Regards,
hng

Hi Hng,

It's a bit unclear for me, do you get nb-iot connectivity in at_client?

COPS will do a search, and return the operators in your area.

24201 holds two things, country code and operator.

242 = Norway, 01 = Telenor.

02 = Telia.

Using the iBasis SIM, you can choose the network. If you want to check with Telia, this is the command:

AT+COPS=1,2,"24202"

Kind regards,

Håkon

It looks like you are disabling the modem, then enabling NB-IoT, as per the specification for XSYSTEMMODE:

Only one supported mode allowed at a time. Use this command before activating the
modem using the CFUN=1 command. If the mode needs to be changed, deactivate the modem
first using the CFUN=4 command.

Have you checked if you have NB-IoT coverage in your area?

Are you able to successfully get a connection with at_client using NB-IoT?

Kind regards,

Håkon

Dear Håkon Alseth

Thanks, I will wait,

Another thing, with NB_IOT, I have lit problem:

1. I use LTE_M to POST to my webserver: it works

nRF9160-SICA

OK

+CGDCONT: 0,"IP","ibasis.iot","10.160.52.35",0,0

OK

%XCBAND: (1,2,3,4,5,8,12,13,14,17,20,25,26,28,66)

OK

Checking LTE_M signal.............

+COPS: 0,2,"24201",7

OK

+CEREG: 2,5,"765D","0110C303",7

OK


Original String is: +CEREG: 2,5,"765D","0110C303",7

I changed to NB_IoT:

AT%XEPCO=0
AT+CFUN=4
AT%XSYSTEMMODE=0,1,0,0

I got reply:

OK

OK

OK

+CFUN: 4

Original String is: +CEREG: 2,0,"765D","0110C303",9

COPS:0 ----------------!!??

then, I couldnt POST by NB_IoT

What is wrong with my NB_IoT?

I am sorry for disappointing you! :( Hopefully, we'll make it up to you soon!

This should arrive with the public release at the end of June, as shown here:

Dear Håkon Alseth

Thanks so much

disappointed 😞. do you know when can we use GPS + NB-IoT, or GPS + CAT M1?

Thanks,

hng

RE: GPS+HTTP POST

Håkon Alseth — Mon, 03 Jun 2019 09:07:17 GMT

Hi,

The current modem firmware, v0.7.0-29-alpha, allows you to choose the system mode via command %XSYSTEMMODE, but it does not support them concurrently, meaning that you cannot have GPS + NB-IoT, or GPS + CAT M1, enabled simultaneously at this time.

Kind regards,

Håkon
