Problem with SIM card: XSIM returns 5

[mmajchrzycki]

I'm trying to connect nRF916 FP1 Preview DK to LTE-M network using LTE Link Monitor but it fails. Below is details about my firmware/software:

Zephyr OS v1.13.99-ncs2

Modem firmware: mfw-m1_nrf9160_0.6.8-30.alpha

nRF Connect: 2.6.2

LTE Link Monitor: 0.7.0

When I'm trying to initialize everything, LTE Link Monitor is stuck on AT%XSIM. Using console, I follow all commands from LTE Link Monitor and AT%XSIM response is:

at%xsim?
%XSIM: 5

The documentation doesn't say anything about such value (5). What does it mean?

Best regards,

Mateusz

Hello,

Please flash at_client_new.hex to your device and perform modem tracing as explained here. Then send me the LTE link monitor log.

Unfortunately, I don't get any trace output. I've tried with your HEX file and also with the one that I've found on the linked page. The at%xmodemtrace=1,2 is returning OK but Tace Collector is not capturing anything. The AT sequence is working as previously (stuck on at%xsim). Maybe the modem firmware (0.6.8) is a problem?

There might be something wrong with the boardcontroller, here's an excerpt from another post;

zephyr_at_client.hex and nrf52_boardcontroller.hex

First, ensure that the proper board control firmware is on the nRF52840. I have attached the firmware, nrf52_boardcontrolller.hex, above. Set SW5 to nRF52 and flash the attached hex using the following command

nrfjprog.exe --program nrf52_boardcontroller.hex -f nrf52 --sectorerase --verify

Then set SW5 back to nRF91 and program the hex file zephyr_at_client.hex with this command

nrfjprog.exe --program zephyr_at_client.hex -f nrf91 --sectorerase --verify

Then reset the board.

Now install Trace Collector in nRF Connect 2.6.2, then open and connect to the nRF91 board. Click "Start Capture".

Open LTE Link Monitor and connect to nRF91. Reset the board once more. Enter the AT command AT%XMODEMTRACE=1,2 and click send. It should return OK.

Now click on AT+CFUN? two times to get the program going.

I'm getting error when I try to download both of your files.
