bluetooth and 8051

hi guys
this my first post so i hope i am in the right forum 😀.

I am a computer engineer and and I am working on graduation project. and i have some question about bluetooth if any one here can help me 😒.

What i want to do :
Send a byte from a mobile phone to a microcontroller (8051) by bluetooth to open some switches depend on the byte I have been sent.

Problems and question :

P1- I am planning to connect bluetooth rs232 like #-Link-Snipped-# to the microcontroller ,Is that possible? , I ment is this device can be connected to the rs-232 of the microcontroller normaly or it need some kind of Drivers or some think like that.

P2- I find many kind of those bluetooth rs232 - Do you recomnd me one you use or know about it that is work fine with some one.

Q1- Is this the write way to solve my problem by useing bluetooth rs232 or there is a better way to use bluetooth with the microcontroller.

Q2- when i sent a byte by bluetooth how it will arrive on the other way , is as a byte or header+byte+"pla pla"?


Plz help me i just have 2 months left to do my project and I dont know what to use and how to do it 😔
