synchronisation of multiple BLE peripherals

Hi

I am looking a simple way to synchronise multiple devices which might be in connected state(and streaming data) or not(storing data on flash).

I need an sync accuracy between my devices of about 100-300 microseconds.

This is should be a common problem no?

I see many articles on how to do it. But what is the simplest approach?

Ideally I would also transmit a 16 bit value to all devices at once.

My device/peripheral is smapling some ADC values with a sampling rate of 1000 Hz.

Any idea?
