How to connect to HC-06 bluetooth module?

Question

Android

I am writing an android application. The user using this application will send some commands to the microcontroller via bluetooth.
Bought HC-06 bluetooth module. I connected everything correctly in the circuit, i.e. TX, RX, VCC, GND. But I can't connect to bluetooth. And the bluetooth itself only responds to the following commands: AT, AT+VERSION, AT+NAMEnewname, AT+BAUDnewbaud, AT+PINnewpin.
Maybe someone has already met with such a problem and could help.

Answer 1

article about HC-05 will not help?

Answer 2

TX and RX change

Answer 3

Late reply but may be helpful to others. The bluetooth module on the computer must contain a com port profile. if the module has a profile, you need to reinstall the driver. (My case).

Answer 4

Try to turn off the module, connect all contacts one by one or together to GND, wait, return all contacts to their places, turn them on and check. It works for me after that, but I need to constantly do this or automate it (it's easier to buy a good module).
