AVR ATmega16 interface with bluetooth
I want to interface bluetooth module to atmega 16..
please help me if anyone has used any bluetooth module ..
i never used it but tilll where i know it uses a serial string formate
i m still studying bout bluetooth working..have no idea bout which BT module wil suit best for atmega16..
have found following BT ic datasheet links..
see i never worked on bluetooth yet so must give me some idea so that i can search how to do that.... from where you got the bluetooth module and the links you have given to me:
i went through the i went through the national semiconductor one LM9838 blue tooth serial port module
you can use that i just required a serial interfacing to exchange the data which will be very easy....
i don't know about the rest two...
my advice (if you havn't got them yet)... please go through every details of that part, see the compatiblity, see weather you can easily interface it collect all the materials and then order it..... do complete all the home work first before you order it.....
not finalized my project yet..
m planning to make a robo car which wil be interfaced with AVR n controlled via cel phone BT ..
its just tht i want to try some thing different..do suggest if got some better idea..
i got this link for BT based smart home..
All i knw bout BT is how it works..
im working on same kind of project . im using aubtm-20 bluetooth module to interface with atmega16..
im gonna use android app to send strings to module.
can you help me with code for microcontroller ?
The coding required to interface the bluetooth module is nothing more complex than the code for serial interfacing. Initialize the uart for the baud rate of your bluetooth module, enable reception and read the data from uart register. Try it, and update here if you face any problem.
Does this uart-bluetooth connection work both way?
I am using AUBTM-20 bluetooth module with atmega16 microcontroller...however, the data that is being sent on the module through phone is not received by the microcontroller..When i connect the module to the PC via terminal, i receive the data..i think the module is not forwarding the data it receives, to the microcontroller..for the microcontroller code, i have initialised the uart and reading data from the uart pin..but it does not receive any data there...what might be the problem? can some1 help? i have to finish this project in another week
