How can I configure the interval of advertising of nRF52832 when disconnected ?

[tianfei00]

Dear all,

       I have been using the example based the example "ble_app_uart" of nRF5_SDK_15.2.0_9412b9. Every time I found that nRF52832 will go into sleepmode after about 206 seconds when diconnected.

      I want to change the interval. But I do not know how to chang it at all. So I need your guidance to teach me  how to change the advertiing interval.

     Many thanks for your help.

And I do a test, if  I configure the APP_ADV_DURATION more than 180 seconds，nRF52832 can not work normally. And nRF52832 will always reset automatically after finished the fast advertising which I congfigured as 30 seconds.

Why nRF52832 can not set APP_ADV_DURATION more than 180s ?

Hi, 

Max. advertisement time with the BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE flag is 180 seconds, see BLE_GAP_ADV_TIMEOUT_LIMITED_MAX. Use BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE if you want to extend the timeout past 180 seconds or APP_ADV_DURATION can be set to '0' if you want to enable unlimited advertising (no timeout).
