" summary

Android Bluetooth low energy discussion shows measurable results: a 100 kB transfer using default MTU/LE1M and a 48.75 ms interval takes ~8 seconds, but increasing MTU, choosing LE2M PHY and the shortest connection interval cuts it to just over half a second; using reliable write requests drops from ~500 seconds to ~10 seconds with the same tweaks. LE Coded PHY extends range up to ~4× (reports of 3 km exist). Mesh control uses a 16-node mesh proxy via two GATT characteristics for in/out and works as shown.
