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,

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. 

This is for electricity meters monitoring in a building

I think a bluetooth mesh network would be a better choice for this.

Indeed - sounds like exactly the kind of thing Meshes were invented for!

and then you're not limited to there being just 2 "stars", or 2 Centrals in range, or ...

About Mesh - Understood, I've been struggling with this for a while.

This is why I'm thinking a star will be better for this case : 

1. The requirement is that an installation of a new peripheral will be EASY. Mesh provisioning of a new device seems pretty complicated last time I've tried it.  Installation is done by Electricians. 

2. This installation can be transferred to a battery operated environment, where I will have to add powered Friend-Nodes .

3. I hope I'm wrong, but the whole BLE mesh looks like it is meant at this stage for lightning projects.

4. Learning curve for Mesh ....Boss man wants this fast :)

Oh...also - key consideration. 

Mesh does not support Coded PHY  ( at least officially ) - which might be needed for more rural environment.
