Issue with 'W' Command "Save color patterns" on blink(1) device #684

I am encountering a problem with the 'W' command, as outlined in the HID command document.

As per the given structure { 1, 'W', 0,0,0, 0,0, 0 }, this command should enable me to "Save color patterns" to Flash. Unfortunately, this command doesn't seem to function properly on my blink(1) device.

While trying to use the 'W' command to save color patterns, the command fails to execute successfully, without any visible changes or error messages in the blink(1) device, and patterns hadn't been kept after the power off.
