3310 is using FBUs protocol. packing and unpacking data to be able to introduce it to your controller is a pain..

use phone that supports AT commands so that you can have easy life

k… we hv found out nokia 6303 tht supports AT Commands…

bt the problem now is how to connect d mobile with microcontroller…

lyk..mobile can b connected to PC using data cable..n it responds well on Hyperterminal…

bt wat abt using same data cable wid microcontroller..!!??????……….

[romel emperado]

if it responds well in hyperterminal using AT commands you can connect it to controller ..

 

check this process..

 

mobile phone <—> max232 <—-> controller.

 

it is done via serial communication..

thanx for d reply….

bt i still hav some doubts

 

we chekd phone in hyperterminal on a system that had NOKIA PC SUITE installed…. 

PC SUITE is needed coz it has got the drivers fr datacable….

 

now d  question is tht…..

Would MICROCONTROLLER b able to connect through datacable n hav serial communication WITHOUT those DRIVERS fr datacable…???

 

 

also…..,

fr process….

mobile phone <

> max232 <—-> controller…

 

[romel emperado]

you dont need any drivers from PC suite

 

I said from my previous post it is done via serial communcation..

 

 

but i need you to answer this question.. what type of cable do you have?

 

make sure you have rs232 cable to have serial communication with the controller…

 

if you are using USB cable then you cannot interface that to the controller using my diagram above about the interfacing…

[Apuva shrivastava]

 

i understand its serial communication….

 

n cable which we hav is a USB to rs232 DB9….

 

 

we thot of USB to rs232 coz datacable of mobile phone has USB at its 1 end and othr end fr connecting to mobile’s port…

here  m sending the images of 2 cables we r thinking to connect…!!

 

wysiwyg_imageupload:967:height=127,width=127

 

wysiwyg_imageupload:datacable for mobile…:height=145,width=192wysiwyg_imageupload:966:height=115,width=154     

 frst 1 is data cable for mobile…its USB end connected to….ths USB to 232 cable..

 

is it wrong..??

[romel emperado]

yeah! its possible but i havent tried it yet. but the concept is the same..

 

 

let me know your progress.

hello apuva,

 

the pics you have shown above cable 1 is connect the mobile(your device) to PC(host) via USB… so the procols will be follwed as USB one… now in pic 2 ys have shown USB to serial converter… the USB side must be connced to HOST and the serial DB9 pin on the device side…. you cannot connet it in reverse way…

i never tried but i studied a little bit in USB so i can say that….
