People tracking and fitness trackers

People tracking and fitness trackers.
Hello. Sorry for beginner question. I trying to develop a real time location system to track people (using rssi) and take data from their trackers (pulse etc). I use a common cheap fitness trackers, they require connection to device (dk nrf52840) to perform measurements (it takes 2 min). Interaction with the tracker perform through Nordic Uart Service.
Its possible to use ble mesh for tracking people with trackers and perform measurements? (connect node to a nearby trackers in range on a schedule). Maybe i'm missing something, couldn't find any examples

Any advise is well welcome. Thank you.
(I know that using rssi and taking measurements for 2 minutes could result poor accuracy, but that's okay in this case.)

(nrf52840, pca10056, s140.)

Hi Danila, 

We have an example in our Mesh SDK v4.2 that scan for beacon and do mesh at the same time. I think you can base your application in that example and send the information about RSSI, address back to a central node. 

This can be used to people tracking , but it won't establish a connection and get the measurement. You would need to develop your application to establish connection and get the data out. I guess there must be some logic need to be implemented otherwise the node has to be connected to all the scan nodes when it's moving around in the building. Maybe it would only advertise as a connectable node every 1 minute or more and advertise as non-connectable in the rest of the time.
