I just start experimenting with an EM7455 module for an upcoming project and I’m trying to wrap my head around the PRI IDs (and files), what are they used for and how they relate to the firmware for different carriers.
I’ve been searching around the net but cannot find much (probably not asking the right questions). Can someone point me in the right direction?
I’m using Verizon. I’ve updated the module’s firmware using Windows and so far everything is working (as far as I can tell). I’m just trying to get a better understanding and make sure I’m not messing something up.
After running 9999999_9904780_SWI9X30C_02.33.03.00_00_VERIZON_002.079_001.exe to update the firmware, this is what I get for the AT!PRIID? command:
at!priid? PRI Part Number: Unknown Revision: Unknown Customer: Unknown
