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:
1、Decodes and encodes bluetooth communication.
2、Interfaced using RS-232 (anything else is acceptable, if you explain or give references for how to use it).
3、Nothing too fancy.
It could be more than one chip.
The microcontroller we are using is AT89C5131. According to its datasheet, AT89C5131 uses the 8051 architecture（Datasheet for reference: http://www.kynix.com/uploadfiles/pdf8798/AT89C5131A-RDTUM.pdf
