Bluetooth 5.1: a big step forward for better indoor navigation
With Bluetooth 5, we took a big step forward in the data transfer standard for short distances. Now, the Bluetooth Special Interest Group (SIG) has announced the new standard 5.1. Here are the details.
Bluetooth 5.0 brought a wider transmission range (up to 240 meters), lower power consumption, faster transfer rates (up to 2 Mbps) and the ability to pair two audio devices with another device. Now the so-called Bluetooth Special Interest Group (SIG) has published information about the new Bluetooth 5.1 standard.
The biggest innovation is a feature called "Direction Finding". With Bluetooth 5.1 it is also possible to determine from which direction a signal is sent. This should make it possible to determine the location with an accuracy of just a few centimeters, instead of, as has been the case up to now, in a rather wide range between 1 and 10 meters.
According to SIG, the new location will play a major role in indoor navigation and replace WLAN-based positioning in the long term. GPS positioning could also be improved, especially in places with poor GPS reception. Of course, the location of the misplaced key or the like should also be easy.
Faster pairing and fewer disruptions
More features of Bluetooth 5.1 are optimized Generic Attributes (GATT) to achieve faster pairing and higher transmission speeds, and an improved Random Channel Index to prevent data packets from "colliding" during transmission, resulting in disruptions or disconnections.

Indoor navigation in museums or large shopping arcades? Do you use this or is the notification about an indoor map always displayed on Google Maps when you leave the store?
Wow it's really good but can I know whether we can use this in offline
"Indoor navigation" is nothing but euphemism for "spying"
Bluetooth is a great way to listen to your music via BT speakers and or headphones /earbuds as I use them daily cycling, I can get all my calls, receive sms and listen to my music 🎶 via Bluetooth but being able to use two different audio devices at once is what I've been wanting for ever, obviously a wider bandwidth means either better quality sound and two Headsets at once. I presume it's just a software issue (maybe hardware I only know so much) but if it is software I would love to see handsets as far back as say SD810, SD820 etc get a Bluetooth 5.0/5.1 upgrade, personally I would pay for this software just to have 2 BT speakers running in stereo would be a great addition to your audio experience.
If anyone knows if this is possible through an app sideload etc please let me know.
Thanks loving this new technology.
