Supposedly Lifx bulbs can communicate with each other on an 802.15.4 mesh network but I am having trouble seeing that in my installation. I have a string of bulbs in fixtures going down my driveway which i would expect to be the ideal demonstration of the mesh since each bulb in line can act as a relay to help move the signal as you get farther from the Wi-Fi Access Point. In theory the last bulb in line should have just as strong a signal as the first one but the RSSI numbers for the AP show the last bulb to be at a much lower signal strength than the nearer ones.
So does this mean the bulbs maintain the direct connection to the Access Point but don't use it and instead relay through the nearest bulb? Or is the mesh used for something else besides status and command signals? How do I verify that the mesh is functioning and what exactly it is doing?
