MCPD Distance Measuring measurements imbalance

[Metran]

Hello

I am doing research for my paper which includes using MCPD distance measuring between nrf52840dk boards. I currently use nrf_dm sample to measure the distances. I have a problem that number of measurements vary greatly to different anchors and in different experiments, for example in one experiment in 10 minutes I have 100 measurements to one anchor and 20 to another, but when I start over again it's the opposite. As this is study for paper I need more balanced data. I tried changing config, especially CONFIG_DM_TIMESLOT_QUEUE_COUNT_SAME_PEER, CONFIG_DM_TIMESLOT_QUEUE_LENGTH, CONFIG_DM_RANGING_OFFSET_US, disabling measurements between anchors, changing adv interval, scan interval and window and few other methods but I can't get balanced data. Is there any solution for this?
Above plots show 3 experiments in the same configuration (nrf_dm sample without any changes) in 10 minutes timeframe

Hello,

Could you tell me which SDK version are you using here? This can be because of the issue mentioned in this thread.

Kind Regards,

Hello,

I use SDK in 2.5.2 version

Hello,

Have you checked the thread I pointed out in my first response? I also recommend checking the distance measurement library, where you can find the configuration used for adjusting the synchronisation of nodes.

Kind Regards,

Hi, yes, it was enough. Finally i have created mechanism in code to block request to each anchor after given number of measurements to balance data. Thank you very much for help.
