Bluetooth transmitter and receiver modules arrived in the mail. Ordered from amazon here and here. I'll be hacking these for a new project where I'll need to send audio wirelessly between devices roughly 6 inches apart.
Walter keeps watch while I plug in the modules to charge.
First test run of the equipment. With the press of a button they are able to sync and send audio over a relatively large range. This guy cut out around 50 meters, with furniture and walls between.
I'm satisfied, and will now see what's inside.
I started with the transmitter module. Opened by sliding a large sharp blade along the seam between covers. I should post a video on my strategies for popping stuff like this open... it can take some finesse.
I found these items inside: x1 stereo audio cable with stereo 1/8th inch mini jack, x1 3.7v Li-ion battery pack, x1 bluetooth/audio circuit board.
Without the battery this guy is pretty teensy.
And should fit this project quite nicely. Next I'll dissect the receiver. I'm expecting a similar-sized pcb inside.
