I have 2 Hm11 Modules. I am able to communicate with each other using basic sketch and Setting AT+ROLE1 in one of the module and AT+ROLE0 in another one. Although I wanted some security so I enabled AT+TYPE3 and set a custom pin using AT+PASS123456 in one of the module. Hoping that it won't accept connection from other devices without pairing and authentication.
But somehow from the master device I am still able to connect to this device even without knowing the password I kept there in the slave(Peripheral mode) device.
Can someone suggest if HM10/11 Modules can enable mandatory authentication for communication ?
If possible? How can I do that ?
