 2. At least one advertisement packet needs to be sent to enable periodic advertising.
 3. It will use the same PHY as the auxiliary packet. Each periodic advertiser has the same parameters as connection. Additionally, the channel is also determined the same way as connection using the Channel Selection Algorithm #2.
 4. Because it is based on extended advertisements, it uses data channels as opposed to advertisements channels.
+5. Periodic advertising supports Adaptive Frequency Hopping (AFH). Similar to Bluetooth connections, the advertiser and synchronized scanners can dynamically avoid channels experiencing high interference, improving robustness and reliability in congested RF environments.

-If the data of the periodic advertisement does not fit into one packet, the AUX_SYNC_IND packet can be followed by AUX_CHAIN_IND packets. AUX_SYNC_IND along with AUX_CHAIN_IND make up a sequence of advertisements forming a periodic advertising train.
+If the data for a periodic advertisement does not fit in a single packet, the AUX_SYNC_IND packet can be followed by one or more AUX_CHAIN_IND packets. Together, AUX_SYNC_IND and AUX_CHAIN_IND form a sequence of advertisements known as a periodic advertising train.
+
+Periodic advertising also supports AFH. Because periodic advertisements use data channels and Channel Selection Algorithm #2, the channel map can be updated to exclude channels affected by interference. This allows the periodic advertising train to adapt to changing RF conditions, similar to Bluetooth LE connections.
