which crc lib?

[vovagorodok]

BleOta uses default CRC32 calculation. Find nodejs library with that

[sdetweil]

thanks. first two produce different results...

Hmm, am I understand correctly uploader.sh and flutter app has different crc result for same binary?

[sdetweil]

correctly uploader.sh and flutter app has different crc result for same binary
no, you just use two different approaches, flutter is from one buffer, uploader is incremental

man this is harder than it should be

download the same file from the same server, wrote a node test app

same crc as your lib
your lib gets the data from my app (so that is good)
my app calculates from full data (like you flutter app) like the node test app

node test app 226795867
your lib 226795867

my app BEFORE sending the data 3074055154, technically the crc lib returns signed number -1220912142

finally had to embed in source
