hey fast96pgtze-T,
i have used the easy-Radio Transceiver Modules in the past.
note that i used the Transceiver Modules on their own rather than the pre-built boards that Active Robots are selling.
specs here:
http://www.lprs.co.uk/main/product.info.php?productid=199i got around 50 meters range out of these indoors, with random furniture and partition walls in the way without paying any particular attention to areal mounting location, etc.
while it would definitely be possible to get better range than i did with a bit more care when designing circuit boards and mounting aerials, i'd say the quoted "Range up to 250m (line of sight)" range applies only to out door applications and you would only get this in ideal situations with some sort of flow controll in software to test for mistransmitions.
as for using these modules with other software,
they are fairly easy to use in any application that uses your computer's serial port.
in my project, i had a PIC microcontroller, attached to a PC's serial port using the PIC's UART using a max232 to change the voltages between the TTL of the PIC and the RS232 voltages of the PC's serial port..
once i got the application working using a serial cable it was a simple matter of inserting the easy-Radio modules between the PIC and the MAX232.
when the distance between the easy-Radio modules was small the whole project worked first time without any other changes.
at longer ranges occasionally a bite would not arrive or be the wrong value, presumably due to radio interference. as a result i implemented a checksum at either end of the link. when ever data was transmitted i would also transmit a checksum .(i just added the values of all bites transmitted and transmitted that total at the end.) if the message did not match the checksum then the receiving end would request a retransmission.
so in answer to your question:
I was wondering if these telemetry modules were capable of interfacing with all programs and if they are capable of performing the need tasks.
that all depends on how your application is connected to your laptop.
if you are using the serial port then yes, these modules would be usable without changing your application much.
at short ranges you can think of them as a replacement for a serial cable only wireless.
at longer ranges you will have to accept that occasionally a transmitted bite will not arrive or be corrupt.
all the pre built boards i have seen using these modules also use the serial port.
Active Robot's "Radio Data Modem - USB Radio Telemetry Module" for example appears to the PC it's plugged into as a serial port. it has in effect a USB to serial converter built in.
so, some questions about your application:
how are you connecting your project to your laptop?
do you need 2 way communication or is simply sending information to your motors enough?
what sort of environment are you dealing with? will there be obstacles in the way? will the remote end be moving or in a fixed position?
dunk.
