CC2650STK: How to achieve time synchronization between two devices using TI-RTOS

myc

Part Number: CC2650STK

Dear Ti engineer,

is there any easy way to implement time synchronization between two devices, which will make two devices set up a common notion of time, instead of only know the time since each of them was powered?

Thanks

Hi,

Thank you for reaching out.

You should start by reviewing the way the RTC clock works on CC265: https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/487901/aon-rtc-examples

Then, there is quite a lot of resources out there dealing with clock synchronization:

I hope this will help,

Best regards,
