help in transmitting data from cell phone to receiver

[rimshiv]

Hi,

I am doing a project where currently I m sending data from pc to MAX 232 to a transmitter that transmits data at 433.92 MHz AM band and then a receiver receives the data which then goes to the micro controller and then does things according to the data.. now I want to add in my cell phone to this loop such that the data packets are produced in cell phone and then sent to the transmitter somehow.. I do not want to go through the pc. Is this possible by having another device that gets the data packets from cell phone and sends it to transmitter?

Some further info.. I need to send data back like a confirmation back to cell phone.. so would this device be capable of sending data back when connected to the receiver?

I appreciate any help in this matter. Thanks.

Hi,
I think your cell phone should have some communicate interface, just like bluetooth, IR, wifi and so on and have opreation system.Then your project is viable.
For example, if your cell phone has bluetooth and opreation system. You can design a tansmitter to link with cell phone through bluetooth.And you need to write a software running in cell phone.Then you can send and receive data with cell phone.
If you need more information, can contact me:ruixuedz@gmail.com

Thanks for the reply and yeah I was thinking along the same lines.. but I still have the same problem. Let me give a little bit more info. Say I m using the iPhone and do develop a software that can create the corresponding data packets based on the user input, now the problem is the connectivity of the iPhone to the transmitter/receiver. The iPhone can send signals in bluetooth/infrared.. while the receiver can receive signals only in 433.92 MHz (the receiver I am using is: http://www.rentron.com/remote_control/RWS-434.htm).

So the problem comes from the fact that I do not have a receiver that can receive data packets from the iPhone. That is where I needed help.. any input is appreciated.

Thanks

Sorry.. also wanted to ask one more thing.. while we are at this point, I needed to ask about the power consumption of the chips. Currently as I stated, I am using pc --> max 232 --> transmitter --> receiver --> mcu (Basic Stamp 1). All these chips need 5V of power. I was thinking of using 4 AA batteries = 6V and then using a voltage regulator to make it into 5V. Is there a better way to do this? Also, how long would the battery last for? Because maximum battery life is another main concern. I am not sure if it is possible to keep some/all of these chips into sleep mode such that they only use up power mostly when active.

The chips I am using:
Transmitter: http://www.rentron.com/remote_control/TWS-434.htm
Receiver: http://www.rentron.com/remote_control/RWS-434.htm
mcu: http://www.robotshop.ca/parallax-basic-stamp-1-microcontroller-module.html

Thanks
