CC2640R2F: Using real time clock to synchronize two BLE devices

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2650STK,

Hello,

I want to synchronize two BLE devices (CC2640R2F and CC2650STK) without any communication between them. I want to modify some data at a define interval (seconds) in both devices.

Is there a way to do this using some RTC or timer, so that the devices remain synchronized for a long period (weeks or months) ?

Without any communication, I think it is not feasible.

Hi Calin,

I just want to expand on what YK said; for two or more devices to synchronize you need some form of communication between them, make it be wired or wireless communication. However, after synchronization, you can keep them synchronized for some prolonged time before you have to re-synchronize.
