Since Spark Fun discontinued the version of the BlueSmirf that I used in the first edition of Making Things Talk, (the BlueSmirf v1) I’ve had a few requests for the data sheets, etc.  Apparently a number of people (me included) still have them and use them.  The AT commands appear nowhere online that I’ve found, so here’s what I have:
