I am also having the same problem on two hc05 boards I got from DSD Tech
I am using SoftwareSerial to try to communicate with the module.
I have also used a restart method that directly connects to Rx and Tx using delays before sending the AT commands.
I can not get a response from the board in AT mode.
Felic, if you could post where you got the board we can see if it is a manufacturer error or something.
