Calculate File CRC32 (LCC.web_file.crc32)

Signature​

checksum, err = LCC.web_file.crc32(path, timeout?)

Parameters​

  • path
    String. File to check.
  • timeout
    Number, optional. Request timeout in seconds, default 60.

Returns​

  • checksum
    String. 8-character hexadecimal CRC32; nil on failure.
  • err
    String or nil. Error description when the call fails.

Notes​

Computes the file's CRC32 checksum on the controller.
Useful for quick integrity verification.

Example​

local crc32, err = LCC.web_file.crc32("/firmware/patch.bin")
if crc32 then
    print("CRC32=" .. crc32)
end
