+QFUPL: How is the checksum calculated?

[attie-ags]

See my reply to the other thread, here:

CRC32 algorithm

In case anyone else is looking for this information (I’ve looked in the past too), the CRCs are calculated using the following configurations. I’m using the BG95-M3, which has three CRCs in the response from AT+QFCRC: +QFCRC:<crc32>,<crc16>,<crc16_ccitt> Hat-tip to delsum! CRC-32 crc width=32 poly=0x4c11db7 init=0x0 xorout=0x0 refin=false refout=false out_endian=big CRC-16 crc width=16 poly=0x1021 init=0xffff xorout=0xffff refin=false refout=false out_endian=big CRC-16 / CCITT crc width…
