What is difference between
*Memory mapped I/O
*I/O mapped I/O
*Memory mapped Memory
*I/O mapped Memory
Memory-mapped I/O uses the same address bus to address both memory and I/O devices.
I/O-mapped I/O uses the separate address bus to address memory and I/O devices.
First 2 concepts are...
Hello shree4u,
If you receiving OK after LLL its fine, after this you should give ENTER before typing any command (Ex. AT, AT+MODE) & after typing also ENTER command is required...you may be missing out this...try it once...
Hi
As long as you are running the same application then no need of changing configuration else its required to change as per application. If you want connect two bluetooths then use AT+BDISCMODE=3,0 command so bluetooth discoverable mode is enabled(you can search in your mobile this device can...
hi kunal123,
Two things tobe done
1. Set the properties correctly (baud rate,ascii setup,etc..attachment you can see)
2. After every command give enter (when you are connecting to hyperterminal it gives OK then give ENTER then type LLL & ENTER then AT commands..)
try this..
Hello,
You can use Arduino UNO board its easy to learn, interface & which is best for the begginers where you can interface LED's, LCD, Switches, Relay's, Buzzer almost all interfacing can be try..More over codes are already written you just need to see the schematic, rigup the connection, dump...
Only properties changes i made then it started working...actually if all these are done then should work..
when you connect is it giving OK after you type LLL & enter..till what step it is working...
Hi tahertinu,
After connecting Bluetooth to PC with UART, open Hyperterminal, select the COM port, Baudrate(9600)..
Do the Hyperterminal settings ie. File-->Properties-->Settings-->ASCII setup (check the image attached).

hi mpch_elec,
I have worked on interfacing between SIM300 GSM modem & LPC21xx controller & it works well.
Few points tobe taken care
1. Modem has inbuilt max232, so how about uC side.
2. Try connecting straight cable(RS232) between Modem & uC (b'coz i tried with cross cable it was no...
