i have a project to connect a mobile with MCu and the problem now that most the new mobile phones has a USB cable.
firstly i connect the mobile with PC with USB cable and send the AT command and every thing is perfect.
now i want to connect the mobile with the MCU. Is it possible to convert...
i think you have two errors in your code
first you forget the semicolon ;
second you made infinit loop which sends the command infinit times. you should send the command once and make the infinit loop after the command as....

In the sence of electonic devices
1) EPROM - Electrical programming read only memory
It's implemented using MOS transistor for each bit. But the MOS transistor has an extra feature which is called "floating gate transistor" which is simplly a normal MOS transistor with a piece of metal...
Many thanks pisoiu
but what dose CSD means????
and assuming thet the CSD is activated, do i have to configure any parameter in the phone or use any commands before ATD??
My final question.... if i connected correctly and get the responce <connected>, how i can send a packet of data "i.e...
data call atd no carrier
i am useing GSM mobile phone sony-ericsson W800 and connect it to my PC.
i establish a call using ATD command
when i use the voice call command ATDxxxxxxxxxxx; "with semicolon" the call is established correctly but when i remove the semicolon to start data call i...
what is a digital transmitter
You need both transmitter and reciever in both sides. Many RF transcievers avilable.
you can use bluetooth module but you will meet a problems in interfacing USB with microcontrollers. The another solution is using XBee modules which is the latest technology . I...
Many thanks Gorkin for your replay
BUt if you have more information about CSD please inform me
i found only that CSD means "Circuit Switched Data" but it's not AT command
good morning every body
i'm trying to use my mobile phone as modem for real time data transmission
i have implement data transmission system using SMS but the data is not in real time because the SMS is firstly routed and stored in Meaasga Service Center (MSC) then MSC sends it to the...
Mainly, analog filter is designed by op-amp with feedback circuit. Any feedback circuit has transfer function
H(s)= A(s) / 1+B.A(s)
the transfer function is a ratio of two polinomials thats form a IIR filter not FIR
notch + 50 hz + op
Use coaxial cable and onnect the core to sensing electrode and the chees to ground to reduce the picked up noise.
But 50 Hz noise should be removed by 50 Hz notch filter
If you have a design for this filter send it please

DLL or Delay tracking lock loop is a unit in CDMA reciever used to generate the PN code with the same phase of the transmitted one. Any phase shift between the modilating PN code and the Demodulating PN code leads to low signal to nosie ratio.
PLL is exactly like DLL but used in...
HI every body
it's my first message
i need to connect my nokia phone with PC and use AT command. but i have some quistion
1- are all nokia phones support at command? if not is nokia 6110 and 1100 supports?
2- to connect the phone to the PC and using the hyperterminal software; is the correct...
