Is there a way to take an 8bit ascii serial data string (11 bytes) from a serial port and and decode it to hex values?

This conversion doesn't work as I believe it only uses 7 bits. I get mostly bad data.

data = Buffer.from(msg.payload,"ascii");

Thanks, Gary

The buffer-parser node will help.

You might look at bitunloader too, not sure but it might do the job too

Thanks for the reply's. I have it working now. Turns out to have been a serial node configuration error. Once I switched the output type to 'buffer' all was good. It was set to 'string' originally.
