Description

This is my Bluetooth 4.0 to 900Mhz mesh network bridge. Here is a quick summary of what it will do. I plan to use this design as a development platform. There is plenty of room for code, and potential applications are starting to pile up. Possible applications so far are home automation, weather stations, boat monitor (I don’t want any repeats of the early morning fishing trip turned mid scuttle shuffles), and proximity light controller.
