RTC Clock Update using HC-05 Bluetooth Module

Projects Networking, Protocols, and Devices

Hello,
I am trying make a digital clock whose timing will be updated from smartphone communicated with using bluetooth transceiver HC-05. Clock will be updated after every particular time set from arduino.
So my question is that, whether it is possible that , i'll just send any particular command from HC-05 to my paired smartphone and will get the latest clock timing from phone without using any app.
Is there any command that demands for clock timing from smartphone (Really without using any app).... :confused: :confused: :confused:

I Know i can use DS-1307 to get the clock...... But can i also use the above bluetooth method???

No.

Ok, Nick_Pyner
can you provide me any link that explains the process of initial pairing of two bluetooth devices (With commands of pairing)??
May be i'll get some idea or something else from it?

What you ask is far from specific. Pairing is usually done in the settings of a phone, PC, or tablet. You can programme two modules to auto-connect etc.
