@mntmn Well done! I've never seen (or looked for) a _real_ card, just 2D mockups and the specs. Does it work well?

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=big

Thanks delsum!

A swing and a miss! 🤦♀️

This is utterly wild... am I a little smooth-brained, or is this totally unrealistic?

- 200 Mbps compressed to under 1 Mbps
- Realtime, i.e: ~1ms latency or better
- Encode and transmit in <10mW (yes, including radio)
- Lossless
- High-entropy input

... if you succeed, just email them your solution - no mention of any reward or Nobel Prize nomination.
