I used the instructions on this page to bind 2 HC05 modules: [https://howtomechatronics.com/tutorials/arduino/how-to-configure-pair-two-hc-05-bluetooth-module-master-slave-commands/](https://howtomechatronics.com/tutorials/arduino/how-to-configure-pair-two-hc-05-bluetooth-module-master-slave-commands/)  
This worked very well for me.

Are you able to enter AT mode to make the changes? If not, this tutorial may help: [Setting HC05 (ZS-040) to AT mode](https://forum.arduino.cc/t/setting-hc05-zs-040-to-at-mode/1059616)
