I am seeing a significant difference in the range of the Bluetooth signal from different products. My Smart Battery Sense and ip 65 charger appear to be significantly longer range than my IP22 chargers. Is there a reason for this
That’s the nature of bluetooth really - it’s incredibly fickle. “More than a kilometer, less than a meter”, because it is so wildly dependent on so many other factors.
