Philip, you are absolutely right!

I did not realize that for setting 4-bit mode it only requires one
half of a byte, I thought that you had to send the full 8-bit byte
before the module resets itself to 4-bit. Using your init sequence,
sending the resets for both 8bit and 4bit, the display is now
initialized correctly everytime.

Thank you.
