I see an example of a central device and peripherals as one, and I see it using the following three registers to determine the start or end of the broadcast, the beginning or end of the scan, and the beginning or end of the Bluetooth connection during a radio outage:
NRF_RADIO->POWER
NRF_RADIO->FREQUENCY
NRF_RADIO->SHORTS
| NRF_RADIO->POWER | NRF_RADIO->FREQUENCY | NRF_RADIO->SHORTS | remark |
| ==0 | According to the following three judgments is the end of the broadcast or the end of the scan or the end of the connection event | ||
| !=0 | ==2 | ==0 | Think it's the beginning of the scan |
| !=0 | ==2 | !=0 | think it's the beginning of the broadcast |
| !=0 | !=2 | do not care | Is thought to be the beginning of a connection event |
I have not found a basis for appeal in the official documents, I would like to ask if this is a basis? Or can you tell if the scan starts or ends, the broadcast starts or ends, and the connection event starts or ends based on the devices above that are integrated with the central and peripheral devices?
