i want to connect a mobile to a microcontroller using an fbus for our project...its baud rate requirement is 115200bps....is it necessary to use PIC micro controller or can i do the above using some other microcontroller based on 8051...also what is the distinct advantage of using a PIC over other micro controllers in terms of serial data transfer..
thank you for the reply...also i have a doubt that whether the microcontroller will receive the message sent to the mobile on its pins directly after connecting or we have to request the 3310 to send the message...
uC-3310 communication is done with AT Command, uC have to ask 3310 to transfer received message to uC.
Please tak a look at AT Command Set For Nokia GSM And WCDMA Products v1.2 English to understand what AT Command is.
i have seen the embeddtronics webpage but still have a doubt rearding this...also can u tell why we send 'U' 128 times for syncronisation.
The next step is to synchronize the UART in the phone with your PC or microcontroller. This is done by sending a string of 0x55 or 'U' 128 times. Simple! The bus is now ready to be used for sending frames.
AT Command for SMS is a standard set of AT Command, that command is same for all brand of GMS cellphone!
I am having some problems in the circuit for IR transmission and reception.I have designed the 555 Timer for 38KHz but the o/p doesnot go to 0V when a object is detected,rather the voltage drops to just about 3.8V...i am not able to find what the problem is...i am using a 5 V regulator also...
this is the circuit by which i am generating the 38Khz frequency for ir emitter...but i don't know where i am going wrong...the detector senses the voltage drop but only to 3.8V...its output is never 0 even when emitter is aligned to the receiver...i am using 7805 voltage regulator for both emitter and detector with different power supply...should i give timer output to receiver also?
i have connected the fbus tothe computer using serial port and the other end is Nokia 3310..i tried connecting via Windows Hyper Terminal...But the mobile does not respond when i give "AT" in main window.i tried some other commands as well but i don't get any output...i checked using portmon software(sniffer) it gives writing successful but reading failed...what should i do...which other software can i use for interaction and where can i get it..
