Hey guys. We want to work on personal project for indoor navigation using mobile phone and ble bracelet. We want these two together. But if it is not possible at first using one.
We researched on nrf52811 and its feature.
But i think we are faced some challenges.
At first at this time nordic does not have sdk for nrf52811 and find direction until Q3.
We are not a Electronics Specialist or having much experience about embedded system to read datasheet and write library.
So it is not available yet.
But if it is available.
Can older mobile phone with ble 4.2 and above as a transmitter work with ble 5.1 as a receiver?
Or for using direction finding we need ble 5.1 for both side?
Because at this time most of mobile phone using ble 4.2 and above. Not reasonable for implementing this as service for people.
As another challenge i found out each mobile phone rssi have different behavior. I don't know exactly how to handle this.
Maybe for version 1 we need accuracy with 1meter error.
All in all What is your suggestion?
Module of module, algorithm or anything else that is useful.
Thank your for your concern.
Sorry if ask question in wrong category.
