Time Sync between central device and multiple peripheral devices.

Hello NXP team,

I am using Kw45 evk board as peripheral and Kw45-LOC as central.

I am sending time sync to multiple devices using single Central devices, but it seems that time is not synced properly and there is a gap of 1-2 seconds between the time of sensors.

I am using LPTMR to store milliseconds

Hello,
Hope you are doing well.

To better understand the situation, could you share more information about your application?

What SDK version are you using? Are you using an SDK example as base? And how are you configuring and enabling LPTMR in your application?

Best regards,
Ana Sofia.
