issue in Serial LTE Modem v22.04

[praveenpalaparthi]

Hi Team,

I have flashed the given serial LTE Modem hex file(attached) into dev kit nRF9160 and tested TCP server mode.

I am facing issue with AT command: AT#XBIND=3442\r\n, due to this I am unable to open TCP server socket.

Log attached for your reference.serial_lte_modem_22_04.hex

Hi Praveen,
I just tested on a live network with my own TCP server:

Here you can see the server connects and receives the message from the TCP client.

---

However, if I shut down the TCP server and try to connect, I get the same error as you see:

XSOCKET: -116. closed

So please make sure that you have a TCP server up and running that has the correct port open.

---

We will also replicate this on the callbox, but this may help you a bit comparing live network results vs. callbox.

Hi Praveen,
Please follow the instructions given here:

Hi Martin,

Checked at server it is not closed.Its in listening mode.

We are using Hercules application- TCP server as shown in below picture.

Here I am also attaching our Call-box profile file. Please rename the file to *.dfl

kk_nRF91.txt

[Martin Lesund]

Hi Praveen,
I am not familiar with that setup.

Please follow the instructions given in the link provided in my last reply, since that is what we have tested and know works, then if you have any issues with that we can much easier support you.

BR,
Martin L.
