Hello everyone

I am facing very strange issue. I am using "hc01.com" bluetooth modules.

I am using three bluetooth module. one as master and other two as slave. when i try to do inquiry(AT+INQ) using master bluetooth i am only able to get one slave bluetooth MAC address not second bluetooth MAC address.

But for same second bluetooth module i am able to see its name in android mobile.

If i replace that second slave module to new slave module(fourth bluetooth module) then i am able to get both slave module.

Please guide me for any suggestion or any solution.

Thanks.

HC-05 can only connect to one other at a time. The fact that the phone can see the other one, suggests that there is nothing wrong with it.

He should be able to see both addresses/devices though....right?

Before pairing with ONE of them?

I am connecting one at a time only but in inquiry list it should be display both slave devices address.
