Algotithms to perform Time Synchronization of multiple nodes, preferably all nodes in a mesh network?

[MJung.6]

Hi experts,

I am looking for algorithms or any examples demonstrating time synchronisation of nodes in a BLE mesh network. It may seem to resemble to NTP server for time synchronisation. I want to have more accurate, within 5ms accuracy of synchronisation among the nodes in a mesh network.

If any one knows any algorithm or examples provides such results please share with me.

Thanks

Hello,

Did you look at Time Model from Mesh Model specification ?

I am not confirming if this solves your requirement, however, it will be good idea to review the standard. For example, please go through the following section in the standard "5.2.1.2 Time Set". So, if this message is sent to all nodes in the network, there is good change of nodes synchronisation.
