How long does a Nano G1 Companion last on battery?
At about 90 mA average draw, a Nano G1 Companion runs roughly 1.4 days on a 3000 mAh 18650 cell and 4.6 days on a 10000 mAh pack. Real-world life depends on transmit duty cycle, screen and Bluetooth use.
What is the range of a Nano G1 Companion?
With the stock 2.15 dBi antenna at 5 m, the theoretical line-of-sight range is about 14.3 km. In practice terrain and obstacles reduce it; raising the antenna is the single most effective improvement.
Is the Nano G1 Companion good for a solar node?
It can work, but at ~90 mA average draw it needs a bigger panel and battery than nRF52840-based boards (≈12 mA).
