The main objective of the project is to control several devices/appliances through a mobile phone's infrared signal. I am t say2paul<say2paul@nospam.com> http://www.8051projects.net/forum-t10181.html Well afaik mobiles use an IRDA protocol to implement IR communications.So first of all you need to make your 8051 IRDA ready.Secondly the communicatio sashijoseph<sashijoseph@nospam.com> http://www.8051projects.net/forum-t10181.html Thanks sashijoseph,But I really need a mobile device as I need to develop a logic in mobile device where the mobile device will authenticate the user say2paul<say2paul@nospam.com> http://www.8051projects.net/forum-t10181.html What kind of data should I send from Mobile phone IR to the IR connected to the micro-controller.Is there any particular format for it? Or I can send say2paul<say2paul@nospam.com> http://www.8051projects.net/forum-t10181.html Mobile communication over IR is same like FBUS in some mobiles. you need to send data in packet format.
