low power wireless serial link
Hey,
I am looking at designing a project, and I need a bi-directional serial link between two microcontrollers. Does anyone know any chipsets that could acomplish this. I have the following restrictions;
1) I do no wish to use commercial rs232 transmit/recieve modules as these are too expensive, and two pairs would be reqd for bidirectional comms
2) The link does not have to be bidirectional at the same time, i.e. there is a master and a slave, both will not be transmitting/recieving at the same time.
3) If preferable i would not like to use bluetooth, but if there is no other alternative then this would be ok, hopefully someone could point me in the direction of some good introductory documents and a good bi-dir bluetooth chipset then this would be ok i gues
4) Range is ~20M radius of the xmitter
Thanks alot for any help
