can you once confirm that both the cards are from same manufacture
and are of same specifications ( different cards may have different voltage requirements or different delays )
could you please elaborate more about SL-Commands, I searched on internet but didnt find any proper information.
are you referring to these SL commands 9http://www.bilko-automation.com/Assets/Documents/M3TR1-SLcommands-EN-V3-39.pdf)
What type of touch you are looking at?
Cheap and easy to interface -- Resistive touch ( but single point touch only )
a bit expensive (depends on quality) and needs interface IC -- Capacitive touch ( supports multi point touch )
there are 2 parts in case of touch,
a. Touch panel
b. Touch...
what is your objective??
what you want to achieve?
and what new AT commands you have included in your code?
as your thread says SMS interface, and in last point you said that code for only sending SMS works fine.
so now what are you trying to add?
Hi Adityabhandari54,
it is a 8051 microcontroller.
the instruction set for all of the 8051 variants will be same.
only difference is regarding the memory and peripherals.
so you may try a similar model having same memory, and dump that hex file.

in addition to the suggestions by kgshankar1980
please verify few other things also
1. try to communicate your GSM modem using PC ( hyperterminal or similar software) to check it is functioning properly
2. check whether your modem required full HW control ( if yes you can use null...
Hi billu anand,
as already mentioned by chandu.kurapati you need to work a bit.
but let me explain them step by step ( assuming you are new to microcontrollers, and you have choosen AT89S51 )
1. get a working code of UART communication for 8051 (can be easily found on any blog)
2. make it...
Hello djc,
submit the schematic for a clear understanding of the connection.
from your description it seems that you are getting continuous input, so the led turns ON and OFF continuously.
may be you have to change the HW logic to configure the latch so that it will give the input only once...
