I want to make a mesh network consisting of 1no. coordinator XBEE and 75 no's of Routers XBEEs. The distance between each router will be 60mtrs. Also There will be three digital inputs for each router. I want to address each digital input in series, e.g. Switch1, switch2, switch3.....,switch'n' (diginput1, diginput2, diginput3......, diginput'n').
How to configure each router and coordinator, so that I can get all digital inputs at single coordinator?
