Hello everybody!
I am considering adding wireless capabilities to my new design. Due to the very low expected datarate I am cosidering the Nordic IC's. However, since this is my first wireless endeavor, I have these two questions:
-How can I GUARRANTEE that a packet from an other transmitter that happens to be in range is not to be misinterpreted as a valid packet?
-How can I rest assured that my design will not have the same undesirable effect on others?
The 802.15.4 standard, used by Zigbee, makes use of a 64 bit unique MAC address, obtained by IEEE thus taking care of this issue.
The Nordic nRF2401 has an address field that is not uniquely assigned! Do I have to use some sort of master/slave configuration working with ACKs and packet counters (I intended to use transmitter-receiver and not tranceiver-tranceiver configuration), or add some extra identifying bytes in the data to reduce the possibility of conflict near zero? I can tolerate high packet loss, but not the possibility of receiving wrong data.
Is there a better solution / am I missing something here?
please excuse my poor English!
