Hi,

One idea would be to reduce the advertising interval of the advertiser. A shorter interval means more frequent advertising packets, which increases the probability of synchronization and allows more measurements per unit time. You could also increase the scan window and/or decrease the scan interval on the scanner. This makes the scanner listen more often and for longer periods, increasing the chance to catch advertising packets and synchronize faster. But increasing the speed like this can result in increased power consumption too.

I would suggest you to take a look at the following documentations:

https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/bluetooth/nrf_dm/README.html#power_consumption
