 | Bluetooth: Central Periodic Advertising Sync Transfer (PAST) | 
 | ############################################################ | 
 |  | 
 | Overview | 
 | ******** | 
 |  | 
 | A simple application demonstrating the BLE Periodic Advertising Sync Transfer | 
 | functionality as the sender. | 
 |  | 
 | Requirements | 
 | ************ | 
 |  | 
 | * A board with BLE 5.1 support | 
 |  | 
 | Building and Running | 
 | ******************** | 
 |  | 
 | This sample can be found under :zephyr_file:`samples/bluetooth/central_past` in | 
 | the Zephyr tree. | 
 |  | 
 | Use the sample found under :zephyr_file:`samples/bluetooth/periodic_adv` on | 
 | another board that will start periodic advertising, to which this sample will | 
 | establish periodic advertising synchronization. | 
 |  | 
 | Use the sample found under :zephyr_file:`samples/bluetooth/peripheral_past` in | 
 | the Zephyr tree on another board that will advertise and await a periodic | 
 | advertising sync transfer. | 
 |  |
