Connecting 64 ESP32 together on Bluetooth in BMS sensor network

[Ibrakhattab]

I'm trying to find the best way to connect 64 ESP32 together on Bluetooth, so that I have the minimum of masters. I think to connect them with one master - to save energy- , while all slaves are paird with the master, and the master connect to them in groups alternately, . the master should e.g has a connection to a group of slaves, gets the data and the connect to another group. Does that work with ESP32, and when yes, is this process fast? Have you any other idea to connect all ESP32s with the minimal number of masters? Thanks
