Hi!
Newly using BFT4KB here. We have been using PCEngines products for a while, then Corpshadow's FW series (might be Protectli related).
We always have been using Sierra MC7455 LTE cards.
Now it doesn't seem to work in a BFT4KB : LTE modem is recognized, I am able to send commands via the serial port. However when looking for the SIM status using AT+cpin? command, I always get the message "+CME ERROR: SIM not inserted"
OFC I tried both SIMs slots. I did reboot the unit after swapping.
Any ideas?
