GPS+HTTP POST

[Hoang]

Dear , 

I tried to use HTTP POST to POST the information from GPS to my webserver. 

But I couldn't combine 2 of them together. ( they, GPS and HTTP POST, worked well separately). 

Could you please help me. 

1. GPS: (works)

gps.7z

2. LTE HTTP POST (works)

LTE_Debug.7z

3. GPS+LTE HTTP POST: ( DOES NOT WORK)

GPS_LTE_debug.7z

I couldnt enable GPS when I set: 

# LTE link control
CONFIG_LTE_LINK_CONTROL=y

in prj.conf file. 

Plz help me. 

Thanks so much

I am using: 

ncs_ version:

 v0.4.0 

SES 4.16 

firmware: mfwnrf916007029alpha

Hardware: nRF9160 DK v: 0.8.5

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

Dear Håkon Alseth

Thanks so much

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

Thanks,

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:

Cheers,

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

I changed to NB_IoT:

I got reply:

then, I couldnt POST by NB_IoT

What is wrong with my NB_IoT?

My code:

LTE_M_NB-IoT_debug.7z

Thanks

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

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

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,

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
