Question about Bluetooth duty cycle issue

[AndrewXu]

Dear Nordic support:

How long is the single broadcast duration and the broadcast interval for Bluetooth?  We would like to know what the duty cycle of Bluetooth operation is.

Hi,

The duration of an advertising packet depend on the length, if that is what you mean? You can also configure the advertising interval, and set a timeout if you want the stack to stop advertising after a specific amount of time. Regular advertising can have an interval between 20 ms and 10.24 seconds. It is also allowed with shorter interval for high duty cycle directed advertising for a short time (typically used for instance by a HID device after a disconnect to rapidly re-connect).
