Hello, I have learnt that there are four PDUs in BLE advertising (ADV_IND, ADV_DIRECT_IND, ADV_NONCONN_IND, ADV_SCAN_IND), they are designed for different scenarios. I am not sure if beacon is the same as ADV_NONCONN_IND mode. Since my case is that (in outdoor scenario) nrf52840 advertises certain information, and the mobile phones nearby could receive the information. I think the ADV_NONCONN_IND mode is suitable, but I am not sure if I could set the nrf52840 to be a beacon. Thank you very much!
