The above post link is in relation to my post.
I am using Mangoh Red with HL7800 module. I am using a sim from sierra wireless, well activated as per AIrvantage platform.
It seems that the micro sim receives no power at all, tried to detect the sim using various AT commands but I received either +CME ERROR 3 , +CME ERROR 4 or +CME ERROR 10 in response.
For instance:
>at at!band?
AT at!band?
+CME ERROR: 4
>at AT&K3
AT AT&K3
+CME ERROR: 4
>at AT+KSIMSEL=?
AT AT+KSIMSEL=?
+CME ERROR: 4
>at AT+KSIMDET?
AT AT+KSIMDET?
+CME ERROR: 4
I checked the supply voltage on CARD1_DET pin and found it to be around 300mV (which is too low). We tried to power up the board using CF3 usb, console usb and using an external battery but the results remained the same.
I’ve tried the following dip switch combos: (1,3,4,5 : ON, others : OFF), (1,3,5 : ON, others : OFF) , (1,5: ON, others OFF).
Also, I am getting weird traces on my terminal emulator from the device randomly:

Any help would be appreciated.
