https://devzone.nordicsemi.com/f/nordic-q-a/14358/timeout-for-directed-slow-advertisingIn the BLE advertising library, in SDK 11, is the timeout for directed slow advertising specified in seconds, or in number of tries? Seconds would be more consistent with the timeouts on the other modes (directed fast, fast, slow).

The comment is still there in SDK 13.0.0-1.alpha.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/54814?ContentTypeID=1Fri, 10 Jun 2016 07:54:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9187a4a7-146f-492f-8f70-95228c403cc3MartinBL<p>Hi</p> <p>Maybe I am misunderstanding your question, but isn&#39;t that given by the line above?</p> <pre><code>typedef struct { ... uint32_t ble_adv_directed_slow_interval; /**&lt; Advertising interval for directed advertising. */ uint32_t ble_adv_directed_slow_timeout; /**&lt; Time-out (number of tries) for direct advertising. */ ... } ble_adv_modes_config_t; </code></pre> <p>If you have a slow advertising interval of e.g. 100ms and a timeout of 10 tries your device will be advertising for</p> <pre><code>10 tries * 100 ms/try = 1 second </code></pre><div style="clear:both;"></div>
