Serial LTE Modem TCP/IP Example

[edahlke]

I have programmed the NRF9160 with the Serial LTE Modem example and am following along with the example here - Testing scenarios — nRF Connect SDK 2.0.99 documentation (nordicsemi.com)

First thing I notice is AT#XSLMVER returns 2.0.2 instead of 1.5 in the example. 

When I try AT#XSOCKET=1,1,0 it returns XSOCKET: 0,1,6 instead of 1,1,0,6 in the example. 

AT#XSSOCKET? returns 0,1,0 instead of 1,6,0.

I do get the expected OK response from AT#XSOCKETOPT=1,20,60

The rest of the example trying to connect to port 80 of google.com does not seem to work. 

Any ideas, or perhaps I've done something wrong?

Thank you!

Thank you for the reply.

My local FAE suggested I try using a standard terminal program instead of LTE Link Monitor to send the AT Commands, and this worked. Link Monitor would get hung up after I would send AT#XSEND, and the +++ command could not get it out of of data mode. 

Now that it is functioning properly, does Nordic have a TCP server that echos data sent to it, or is there a public one that you know of?

Thanks!
