Hello all,
Currently I am developing a code in which a central (nRF52840) scans and reads adverisement packets from 2 beacons (no connection required). I decided to use an adress filter to limit the amount of advertisement data received; however, it seems that it is not working because:
1. I´m getting TONS of advertisement packets that don´t look similar to what I´m expecting.
2. The event NRF_BLE_SCAN_EVT_FILTER_MATCH is never triggered.
Below I´ll show you some key points of the code:
