u can use mbus protocol, but u have to connect your phone with microcontroller or computer to send mbus commands which are send at 9600pbs

need the circuit diagram of gsm allarm with pic16f84

hallo

if any body have a circuit diagram with pic16f84 with any nokia mobile phone pls send to me



thanks

ckt diagram is simple just connect pic16f84's serial pin to the mobile directly to Tx and Rx if you are using fbus and if you are using mbus u can connect both pin to single mbus pin on mobile through resistor.

pic Tx --- resistor 220 hms optional ----> Fbus Rx mobile
pic Rx --- resistor 220 hms optional ----> Fbus Tx mobile

pic Tx --- resistor 220 hms ----> mbus mobile
pic Rx --- resistor 220 hms ----> mbus mobile

further more ciruits are given below for pc connectivity
and nokia pins
