(0.89976) \* pow(ratio, 7.7095) + 0.111

Sorry. I don’t understand your question. Could you please describe it?

288/5000  
I’m working with the receiver I mentioned in the title and ptthon in a desktop app, I need to know if they have implemented something for the calculation of distance between the sender and receiver I am using this:  
(0.89976) \* pow (ratio, 7.7095) + 0.111

But it gives me very variable values

Here’s a [function](https://bbs.aprbrother.com/t/how-to-find-beacon-distance-by-the-received-rssi-in-android/425) to calculate the distance of beacon. But it’s also not accuracy. It’s hard to get the exact distance by RSSI.
