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 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:

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

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)

I changed to NB_IoT:

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

I got reply:

OK

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
