Your second option is true, the assembler comes back with

*** Error: Out of range
20 ST LEN(3)

Any value over 0x80 produces the error, so I allow sbasm to assemble the program with 0x75 and 0x76 and then manually change offsets.

Program currently limited to 256 bytes per load, but since each load only takes 1 second to load, not sure if this is a problem.

If you are developing code for the MK14, the M5StickC program could be developed to accept a file from a PC via WiFi. Currently I have to compile the arduino sketch ever time I make changes to the file transfer process or add additional programs.
