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?
