Question about using Xbee to transmit waveforms

Wireless & IoT
1

Hi,

I am new to the XBee modules so I don’t know how to start, what I want is that I want to transmit a piece of 38 KHz square waves using the XBee 1 series. What do I need to do to make it work? I checked the manual and start thinking that it won’t work on XBees since its sample rate only at 1ms the maximum. I appreciate that if someone can help.

Thanks.

that it won’t work on XBees since its sample rate only at 1ms the maximum

That is correct.

And since XBees use a data packet over the RF link there isn’t another way that I can think of.

You might get this to work if you use a ‘simple’ Transmitter and Receiver that can modulate at 38kHz or greater.

Do you need this to be RF?

Would an IR link work?

This is the thing, I am simulating a remote control deivce. I give order on a MCU and I want the target device to receive the command wirelessly and generate 38KHz in some formats, which will be the IR signal.

If the remote MCU is generating the 38kHz and all the is needed over the RF link is a command to say ‘start’ or ‘stop’ the 38kHz and if the exact timing is not too critical (+/- a few 10’s of msec) then you could use an XBee.
