I'm looking for advice or a link, to extend the range of Xbee pro. I've heard the term "Mesh", but no explanation how it works.
I have a tracking solar array controlled by an Arduino uno on the hillside behind my house 170 feet way. I have an XBee pro installed with the Arduino. I'm getting reasonable comms reception (on my laptop using a Xbee pro in a usb) from the upstairs bedroom closest to the hillside, but marginal reception anywhere else in the house.
I think I need to have some kind of mid point repeater and came across the term 'mesh' while searching, but could not find set up information.
Advice or links would be appreciated.
