i am not using gps module. I am using gps receiver. it consists of 8pin.
PIN1: 3.3v
PIN2: ANALOG AND DIGITAL GROUND
PIN3: Rx
PIN4: Tx
PIN5: v-ANT (2.7 TO 3.3V)
PIN6: GND (ANALOG AND DIGITAL)
PIN7: RESET (NO CONNECTION)
PIN8: EXTERONAL ANTENNA

With a good model (I don't know about yours) and good circumstances, it can be pretty low (a couple of meters). Some units will report an
estimate positional error dynamically. (I don't know which models).
I don't see any use of MAX232 or MAX3232... there is no need to convert the signal to TTL logic as both work on CMOS logic.
Simple interfacing RX(of GPS)->Tx(of MCU) and Tx(of GPS)->Rx(of MCU) should work, won't it???
Hi,
I think you got your two connections wrong. they are just interchanged. As tx of gps should go to rx of microcontroller and rx of gps should go to the tx.
So, Corrections should be:
pin10 of max 232 >pin 11 of mcu and pin 9 of max 232 >pin 10 of mcu
