Hi,
I received my Raspberry Pi 5G Development Kit 2 weeks ago, today finally have time to test on it. After I connected the Telit 5G module and inserted the SIM (works my phone), I got the error “SIM not inserted” when try to retrieve SIM information.
I notice the 1st pin seems like is broken compared to the 2nd and 3rd pin.
Appreciate your help on this. thanks.
Assuming it is not a hardware problem, I also had SIM not inserted errors with the Telit fn990.
The following guide for the fn980 helped me solve the issue:
Here are the steps I made to resolve the issue on the fn990:
Steps to detect SIM:
hot swap off
AT#HSEN=0,0
AT#HSEN=0,1
SIMIN polarity to High
AT#SIMINCFG=1,1
AT#SIMINCFG=2,1
Perform MODULE_RESET via GPIO
Drive PIN 13 high and a few seconds later back to low:
sudo raspi-gpio set 13 op dh
sudo raspi-gpio set 13 op dl
