HC-06 ends blinking after a few seconds

Hey,
at first im not sure if this is the right topic.

My Problem is, that i bought 3 HC-06 Bluetooth recievers, but now when i connect them 2/3 are stop blinking after a few seconds, and i cant connect it via Bluetooth.

I connect the VCC to the +5V Arduino
the GND to the GND
the RX to the TX
and the TX to the RX.

I think those modules are 3.3v and like 4.2 max if i'm not mistaking

In the description theres called +5V, but i tried it with bothes.

You need to post EXACTLY what hardware your working with and exactly how you have EVERYTHING wired.

As I said

I connect the VCC to the +5V (Arduino)
the GND(HC-06) to the GND (Arduino)
the RX(HC-06) to the TX (Arduino)
and the TX(HC-06) to the RX (Arduino).
