powering lilypad and sensors

Hy all!

I have a Lilypad, there're some flex sensors connecting to them, and there's a CR2032 what gives power to the flex sensors. If i connect the bluetooth module, neither the lilypad's led won't blink if I press the reset button, nor the bluetooth module's led won't blink.
I think the bluetooth module can't get enough power.

How should I give more power without killing something? I will add more things to the Lilypad in the near future.

Tried to connect the cp2102's 5V to the bluetooth VCC, cp2102's GND to bluetooth GND, and lilypad's rx to bluetooth tx, lilypad's tx to bluetooth rx. Nothing.
I don't understand, the power is from the PC, not from the CR2032 battery. Still no blinking red leds on the bluetooth module.

Tried to connect the bluetooth module with Arduino Uno, with the same program uploaded on there and the bluetooth's red leds are blinking.

What the hell is wrong with it?

Dude, that's like taking your car to the shop, handing over the keys and telling them to fix it.

At least provide a proper schematic of how you have things wired up. What voltage is the battery, how much current does it supply? Sensor specs. Which Bluetooth module, specs?
