Using the PSoC 63 series bluetooth le phy/stacks, are there any ways to distribute a somewhat precise clock between 3+ devices?

Something like a light-weight 'over the air' precision time protocol. Preferably connectionless.

Hi @DaEr_349131 , There is no standard spec to transfer clock without connection between devices in PSOC 6 BLE, However you can explore the Current Time Service which can be used for Time synchronization between BLE devices, but the devices will be connected here. 

CE222604 – PSoC 6 MCU with BLE Connectivity: RTC with Current Time Service (RTOS)

Hi Bragadeesh,

Thanks for reply. The time service requires a phone to be paired and doesn't solve broadcast scenarios.

Are there any other ways of getting a timing determenistic hook from the pre rx and pre tx events!?
