I'm Looking For A Chip That Can Be Used In My Electronic Project

02/28/2017 12:54 AM

My teacher wants to add Bluetooth communication to the electronic project in are school. He asked me to check out the possibility.

I tried googling, but I couldn't find anything I was sure about.

I am looking for a chip that fulfils the following conditions:

· Decodes and encodes bluetooth communication.

· Interfaced using RS-232 (anything else is acceptable, if you explain or give references for how to use it).

· Nothing too fancy.

It could be more than one chip.

The microprocessor we are using is AT89C5131.

ask your teacher

otherwise

perhaps https://www.bluetooth.com/develop-with-bluetooth/developer-resources-tools

(+ an overshoot but a possible source for detailed low level spec.-s if such required https://www.inf.ethz.ch/personal/hvogt/proj/btmp3/Datasheets/Bluetooth_11_Specifications_Book.pdf)

Nice article, lovely use of the word Guru, but KangaRoo is the correct spelling for our spring loaded mouse....

I have used hc-05 modules before and had good luck with them. They run between about $4 and $10 depending where you get them; you can find them on Amazon and Ebay (just search hc-05).

The only tricky thing, which may or may not be an issue for you, is they output 3.3v signals so you may need a level converter depending on the project. If I remember, they are tolerant of 5v data inputs (but don't quote me on that).
