Connect to closest Central

[ran]

Hi, 

Let's say I have 2 nrf52 Centrals in a room , now - I'm adding a peripheral and I'd like it to connect to the central with the better RSSI ( out of the 2 ) 

My idea involves role switching and seems pretty complicated. 

Thanks,

That helps you with obtaining the RSSI value at each Central separately.

It doesn't help you with how one Central knows the RSSI at the other.

Since I have my peripheral connected to 2 centrals now, I can get the rssi of the connections , and then decide which connection I should drop. 

I didn't think a peripheral can be connected to more then 1 central until today :)

OK: so instead of the original proposal, where the Centrals decide between them before making any connection, you're now going to have the Peripheral connect to all Centrals, and then decide which connection to keep?

Which should achieve the same end.

The only slight downside is that it means more "intelligence" in the Peripherals - which is usually the most-constrained device.

It also means more radio traffic.

But these things may not matter in your use case.

Any particular reason why you need this complication ?  Why not just reverse it.  2 periph instead of 2 centrals, and the centra (instead of periph)  decides which periph to connect to ? Wouldn't that be simpler ?

Hi, 

Imagine 2 stars ( central connected to 4 peripherals ) . 

Those 2 stars can overlap. 

I'd like to add another peripheral to the 1st star. Both Central are in range, one will be further away. 

So - I need the peripheral to automatically "choose" which central should connect to him.
