Wireless synchronization using low power mode

[Mehdi]

Hello,

I'm developing a custom application based on SDK 15.2 on nRF52  using softdevice S132 v6.1.

In my development, I want to ensure timestamp synchronization between 2 devices, so I integrated the provided synchronization implementation to do it.

If I understood the implementation correctly, the power manage is deactivated in this example.

So, a power manage activation in my application layer can impact the synchronization ??

Best Regards,

Hi

Due to the Easter holiday we are understaffed and you will have to expect delayed replies. Sorry for the inconvenience!

Where do you see that the power management is deactivated? It is enabled in both central and peripheral config files. In the peripheral side main file, the power management is active as well, able to go to both low power and system OFF mode. The reason the power management isn't mentioned central side, is likely because it is connected to a constant power source, like a computer or similar, so that it doesn't need power management.

However, if you were to implement power management central side, that might compromise the synchronization, as the timer, and maybe clock source, responsible for the synchronization will likely be deactivated by low power modes. You can probably reduce the current consumption somewhat by disabling the peripherals and stopping the timers not needed for certain periods of time, but you have to make sure what manages the synchronization is active for as long as you want the devices to be synchronized.

Best regards and happy Easter,
