Some basic questions about Zigbee and wireless
I am trying to migrate from RS485 communication to wireless for my projects. I have decided to use the wireless module made by Microchip.
My questions are
1. Is the wireless communication full duplex. (ie: the module can send and receive at the same time), in the RS 485 single master network only the bus master could transmit while the slaves listened and transmitted only when asked for.
Is this the same for the wireless system???
2. Is it absolutely essential to use standard wireless protocols like MiWi or Zigbee etc ??
I am not sure these protocols could be accomodated on a small mcu like 16F648A or 16F88, so I may have to design one myself.
3. Can the module be housed inside a metal casing ???
