Hi,
I'm currently working on getting LTE to work on our custom card, featuring an nRF9161 and an MFF2 eSIM (without PIN), but I can't seem to initialize our eSIM. I have flashed the latest version of the modem firmware available (mfw_nrf91x1_2.0.1) to replace the factory test one which comes by default. I saw that the modules come without an IMEI number, so I created one and programmed it with the following command:
AT%IMEIWRITE=0,"<my_IMEI>"
Despite this, I had no LTE connection. Continuing my diagnostics and comparing with what I have on the nRF9161-DK, I saw that when I initialize the modem and run the following command, I get a different response that indicate a Universal Subscriber Identity Module (USIM) card failure (see here).
nRF9161-DK
Send:AT+CFUN? Rec: +CFUN: 0 OK Send: AT+CFUN=1 Rec: OK Send: AT%XSIM? Rec: %XSIM: 1 OK
Custom board
Send:AT+CFUN? Rec: +CFUN: 0 OK Send: AT+CFUN=1 Rec: OK Send: AT%XSIM? Rec: %XSIM: 0,9 OK
Are there any other commands and/or initialization I need to do on a new nRF9161 to get it working?
Thanks,
Michael
