https://devzone.nordicsemi.com/f/nordic-q-a/26133/sdk14-radio-notification-unstableI am using radio notification to change every advertisement packet. Here is my code: static void on_ble_radio_active_evt(bool radio_active) { if (radio_active) { advertising_data_init(); m_dynamic_adv_counter++; } } int main(void) { ... err_codeen-USTelligent Community 13Wed, 08 Nov 2017 15:16:37 GMThttps://devzone.nordicsemi.com/thread/102986?ContentTypeID=1Wed, 08 Nov 2017 15:16:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:103a35d3-1b61-4347-bad1-3dd30c76d77cHung Bui<p>Could you provide an example so that we can reproduce the issue here ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/102985?ContentTypeID=1Tue, 07 Nov 2017 17:06:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4b66263c-09e4-46d9-adb8-f20407978e01Rbai<p>I checked but we do not write to flash in our app. I think you should be able to see it by just running a simple advertiser and print something in the on_ble_radio_active_evt(). You should see sometime there is a flood of prints in COM port console. Due to this issue we are currently not using this radio notification method.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/102984?ContentTypeID=1Mon, 23 Oct 2017 10:21:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e199aee-37e7-4aff-b6c0-93edbbd45f52Hung Bui<p>Hi Rbai,</p> <p>If you have a look at the softdevice release note, &quot;Limitations&quot; you can find that:</p> <blockquote> <p>If Radio Notifications are enabled, flash write and flash erase operations initiated through the SoftDevice API will be notified to the application as Radio Events (FORT-809).</p> </blockquote> <p>I suspect the irregular period of 5 seconds could be related to flash activity in your application?</p> <p>Could you please check if you have any code doing flash in the period ?</p><div style="clear:both;"></div>
