ESP32 Bluetooth on Wroom

[sorova]

I have a Wroom bluetooth module I am working with. I will need three in total and I have a 4th processor which will do image processing - let's say a Raspberry Pi. The Pi will do image processing and send x,y,z coordinates - just integers, to the three separate ESP32 devices. I was thinking of sending the information via Bluetooth, but can you send from a Pi and have it connect to three separate slaves? Or let us suppose I decide to use a 4th ESP32 processor instead of a pi for the image processing, can I send from it to three other ESP32s? If bluetooth isn't possible maybe I could use I2C, the connection doesn't have to be wireless.
