Bluetooth range
What can cause my iPhone 6splus bluetooth range to be very short and what's the solution
Consumer Bluetooth by design has short range. Around 30 feet or 10 meters is the maximum range assuming there is no interference of any kind.
Normally, about 9 to 15 feet or 3 to 5 meters is the average range.
Are you saying you have a lower range than that?
What kind of range are you expecting?
