I'm trying to connect HC-05 to a device (HC-05 connected with Arduino Uno), I managed to enter the AT command and currently in process of connecting it. here are the pairing command: ` * AT+UART=57600,0,0 AT+ROLE=1 AT+PSWD="0000" AT+CMODE=0 AT+BIND=C464,E3,EB8454 AT+IAC=9E8B33 AT+CLASS=0 AT+INQ…

I solved the problem by upgrade it to VERSION:4.0-20190815 from VERSION:4.0-20190728

HC-05 does't return ok for few commands

Are you sure that it is a HC05? Post photos of the module, front and back.

How are you communicating with the module? What baud rate?
