Probably wiimote speaker audio will still be broken.

But will be nice to give it a try.

I think you can add 2 diodes at the 5v line antd make it 3.5v.

Very risky. Such a chip is also able to not use any power at all (<<1mA), so it would still get those 5V. And please don't talk about a parallel 300 Ohm resistor.

Not sure why, diodes will take 0,7v each in serial connection.. But, a voltage regulator will be the best option. You can get some from Xbox 360 boards. The DVD drive uses 3.3v.

Also there are tons of BT dongles using bt2045 chip.

So, probably wont change anything for dolphin users. Maybe better range.

My homemade USB sensor bar uses diodes for a voltage drop, and they work exactly as intended, and don't get any hotter than the LEDs themselves (as they've got no more power dissipated through them). In this case, a chip causing a 3.5V drop is going to put out more heat than a pair of diodes with a combined 1.5V drop when the current is the same, so if the chip's not melting, then the diodes will be fine.

Glad to see this is proving to be useful. Let me know if there is something I can do to help.

For powering it, just use a linear regulator. They are cheap and easy to wire up. The current draw fluctuates quite a bit, and the diodes won't provide a stable dropout at different currents. Resistors also aren't good because the voltage will change based off the current draw. Voltage dividing circuits are for reference voltages, and should not have loads put on them. Any 3.3v regulator will work, but linear ones are better suited for this situation for simplicities sake.

If you aren't sure, use this one. You won't need to wire up a feedback pin to calibrate it, since it is already set to 3.3v:

Yes, and nothing else. It may work with a diode and a resistor (parallel to the bluetooth chip), but quite risky...

Hi!
Do I Have to connect the "test pads" under the sticker (black circles in the upper right Corner of the right module on the first pic of this post) also to ground?

Hmm... connected everything as you said. But the bluetooth module is an "unknown device". Tried to installa bt2045 driver but this didnt help

Can you help me?

The wiring description in the first post is wrong:
green dot ist green usb wire but data- (not data +)
white dot is white usb wire but data+ (not data-)

I tried to connect a 2in1 remote this way with the pc, cause i thought, that when the 2in1 remotes can connect to a wii console, they should also connect to a pc using the wii consoles bluetooth board. But it doesnt work. The 2in1 remotes are not recognized (other bluetooth devices are recognised so the module is working)...

edit: they also dont connect using the toshiba stack...
