Thank you for this, I'd had something similar written, so it's nice to
see I was kind of on the right track! I tested this on my Thinkpad
X13s with an H2GO bluetooth Speaker and the range I can get is far
greater when it properly loads the b8c file (with this patch), than
with the .bin (without this patch). Thanks again!
