I need to change the interval to lower / higher based on the user phone. For example, if its IOS I will set the interval longer to save current. If its android, I will set the intervalen-USTelligent Community 13Mon, 06 Apr 2020 13:18:04 GMThttps://devzone.nordicsemi.com/thread/243672?ContentTypeID=1Mon, 06 Apr 2020 13:18:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b8b54f3-1da4-49b4-a550-3625a1aa7715kfcube<p>got it, thanks a lot</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/243661?ContentTypeID=1Mon, 06 Apr 2020 12:57:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e544b1f4-dfc1-4553-b271-95cc391ae7f2Einar Thorsrud<p>Hi,</p> <p>Yes, there is no need to reset the nRF in order to change advertising interval. The advertising interval is part of the configuration struct (ble_gap_adv_params_t) that you pass to&nbsp;sd_ble_gap_adv_start() if you use the SoftDevice API directly.</p> <p>If you use the advertising module, this allows you to configure a few advertising intervals (fast and slow), but does not have API to update it. You could modify the module to allow you to update it though, or as a hack, you could remove static from&nbsp;m_adv_modes_config in ble_advertising.c, and declare it as an extern in your code, and set&nbsp;m_adv_modes_config.ble_adv_directed_slow_timeout and/or&nbsp;m_adv_modes_config.ble_adv_fast_interval the new values before you start advertising with&nbsp;ble_advertising_start(). This is of course not very clean but demonstrates how you can do it.</p><div style="clear:both;"></div>
