NRF9160 AT Command, HTTP, NB-iot

Hi Elfving,

Sorry for the late reply.
My ncs is 1.7.0 and mfw_nrf9160_1.2.3.
Instead, I managed to send it using the TCP/IP method.

Currently I'm trying to use the latest ncs 2.4.0.

But the modem did not reply to my command. I'll try to figure it out.
If I still cannot, I'll create a new ticket.

Best Regards,
Rezan

Hello again Rezan,

That is odd. What NCS version and Modem FW version are you using?

Regards,

Elfving

Hi Elfving,

I did test. But I cannot send data. From the command I can connect to the server port.
But when sent "AT#XHTTPCREQ" straight get "ERROR" return without delay. What is the possibility?

AT+CGDCONT?
+CEREG: 1,"746F","03F7D27B",9,,,"11100000","11100000"
+CIND: "service",1
+CGDCONT: 0,"IP","m2mxnbiot","10.247.100.205",0,0
OK
AT+CGACT?
+CGACT: 0,1
OK
AT#XHTTPCCON=1,"postman-echo.com",80
#XHTTPCCON: 1
OK
%CESQ: 68,3,21,3
%CESQ: 77,3,21,3
%CESQ: 59,2,21,3
%CESQ: 50,2,22,3
%CESQ: 45,2,22,3
%CESQ: 40,2,24,3
AT#XHTTPCCON?
#XHTTPCCON: 1,"postman-echo.com",80
OK
%CESQ: 39,1,19,2
%CESQ: 41,2,24,3
AT#XHTTPCREQ="GET","/get?foo1=bar1&foo2=bar2"
ERROR

Thanks & Best Regards,

I just checked.

The SLM sample shouldn't have any limitations in regards to mode. So yes, NBIOT should be supported.

Not yet. As I'm based in a place which doesn't have the network. Need prepare the device first then will go to the place that has the network and run the test. So I need to minimize the possibility that it is not working.

I believe that should be fine. Are you getting any issues using NB IoT with SLM?

Hi Elfving,

Thanks.
Using SLM does it matter using LTE-M or NBIOT?

Hello,

Have you had a look at our SLM sample HTTP client AT commands?
