Help needed on PIC 16f877 wireless

[karthi27]

I need to transmit an 8bit code from one PIC IC to another PIC IC in the proximity of 10 feet...
Please suggest me the hardware and code / algorithm to get it done...

U can use RF or infrared signals.Post ur code and circuit as per ur req. we will help to troubleshoot ur code or circuit.



Good luck.

Am starting from ground zero for wireless communication using PIC.
I need to transmit the temperature and blood pressure values wirelessly, out of line of sight, for a maximum of 15-20 feet within a home.

My code converts these analog values into 8 bit digital codes.
I need to transmit these codes wirelessly.

What is the best mode of communication?
Is bluetooth advisable?
How do I interface it with my PIC microcontroller?
Please post a sample circuitry & algorithm...

Hi,

You can use these lo cost Sparkfun boards 315 or 433 mhz.

You need to use Manchester coding otherwise you will pick up every transmission going.

Bluetooth is possible but a lot more expensive, you also need to check the range as many cheaper modules can only do 9-10ft.
