H Igor, Im facing an issue when using is SQ as server to accept POS transactions according to new logical i add. But all POS sends ASCII /utf8array encoded message to SQ. At my end why i convert using .toString('hex'), the result is different than the one i excpected.

here is the result after hex convertion 16030100FFFD010000FFFD030312607EFFFD3A5DFFFD46FFFDFFFD5A6A614DFFFDFFFD350E4CFFFD5EFFFD4F4D53FFFDFFFD3E6C68FFFD00002EFFFD2BFFFD2CFFFD2FFFFD3000FFFD00FFFDFFFD09FFFD0AFFFD13FFFD140033003900320038FFFD07FFFD1100FFFD00FFFD002F00350005000400FFFD01000064000B000403000102000A00340032000E000D0019000B000C00180009000A00160017000800060007001400150004000500120013000100020003000F00100011000D0020001E060106020603050105020503040104020403030103020303020102020203

Hi!

Which one do you expect?

You may refer to toString() method specification here: https://nodejs.org/api/buffer.html#buffer_buf_tostring_encoding_start_end

I suggest you debug your logic, dump the contents of your Buffer object and see how source data corresponds to what stored inside object and where it may get skewed.
