       The 32-bit CRC used by Quectel's AT+QFCRC command is a mystery, and there are a handful of unresolved posts on their support forums. I have no idea why this seems to be guarded and isn't in the manual.So here you go, in case anyone was looking. It seems to be a non-standard configuration of the common polynomial (i.e: Ethernet, Gzip, etc...)crc width=32 poly=0x4c11db7 init=0x0 xorout=0x0 refin=false refout=false out_endian=bigThanks delsum!https://github.com/8051Enthusiast/delsum
