HC-05 Bluetooth Module with arduino

Hello guys,

I'm new here and I'm facing some problems while try to communicate with pre-designed hardware with my hc05+arduino uno.

Problems I faced is as described bellow.

1)How can i connect my hc05 automatically with pre-designed device? I've address of bluetooth used in device. Is it necessary for me to change mode of my hc05 to master?

2)How I come to know that my device is exactly connected with the device I want to connect? Any feedback signal or any function to check it?

3)I want to send command to my device via hc05(i.e. If i send command like read mobile number then device must be respond with mobile number only) How can I read command which are sent to device via hc05?

Thanks in Advance..

What is the pre-designated (?) device.

What software is running on the device to receive and respond to commands from your Arduino?

Can you post a list of the commands it can respond to?

There is TGAM chip and Bluetooth in pre designed device. Which read brainwave data like attention and meditation.

Suppose if i send command like brain.readAttention() then it will send value of an attention. I'm using brain library for simplicity purpose.

You must know if the pre-designed device use classic Bluetooth or Bluetooth Low Energy (BLE). The HC-05 does not support BLE.

Classic Bluetooth module is used in pre-designed device

Help people to help you. Post a link to the datasheet or user manual for this mystery device.
