Dear Nordic team,
we are evaluating the nRF9151 for a data acquisition application/device. Our first goal was to get the official HTTPS client sample to run on the nRF9151DK, but have run into an issue with a UICC failure which I couldn't solve so far.
I've been trying to run the official HTTPS sample with SDK version 3.3.0. The output of the sample application is as follows.
*** Booting nRF Connect SDK v3.3.0-ba167d9f3db4 *** *** Using Zephyr OS v4.3.99-fd9204a02d52 *** HTTPS client sample started Bringing network interface up Provisioning certificate Certificate match Connecting to the network +CEREG: 90 [00:00:01.019,073] <wrn> nrf_modem_lib_netif: The modem reports a UICC failure. Is SIM installed?
As per the output, the SIM card does not seem to be recognized and at this point I am unsure whether this is a hardware or a software problem. What I've tried/checked so far:
1. inserted one SIM card which came with the development kit and one SIM card which is known to work in another device
2. made sure the SIM cards are inserted correctly
3. made sure the jumper on P30 is connected
4. Added AT command "AT%XSIM?" to the sample which returns "%XSIM: 0" (which seems to mean it's not initialized?)
5. Tried the advice given in this thread: https://devzone.nordicsemi.com/f/nordic-q-a/128147/nrf9151-dk-uicc-failure-no-sim-vcc-after-previous-softsim-usage (all commands yield "OK")
Am I missing some hardware-side configuration for the nRF9151 development kit?
Best,
Tom
