dmjlambert: Just curious, how did you figure out you had CC-41A?
Several hints that will tell you it's a CC41-A clone:
-It's missing a crystal in the top left corner (placing the Bluetooth antenna on top facing you) See http://wiki.makespacemadrid.org/images/7/72/HM-10-fake.jpg
-It needs CR+LF terminated commands to reply. Original HM-10 will reply to any unterminated AT commands
-Doesn't support usual commands like AT+ADTY3 or AT+DELO2 needed for best performance as a beacon. When you issue an unsupported command you don't get any reply at all in a clone
-First commands you try, like AT+VERR? or AT+VERS? following usual guides don't return anything.
Im telling you as I fell for one of this. I found an article on how to flash them (using an arduino in between) with the original HM-10 firmware thou
