https://devzone.nordicsemi.com/f/nordic-q-a/34051/nrf52840-pdk-eddystone-beacon-updateHello. I&#39;m modifying the Eddystone Beacon Application example. For now, I can transmit my own Eddystone frame. This frame is static, and the board starts transmitting it because I use the following code: With &quot;nrf_ble_es_init (on_es_evt)&quot; the boarden-USTelligent Community 13Fri, 08 Jun 2018 12:15:30 GMThttps://devzone.nordicsemi.com/thread/135357?ContentTypeID=1Fri, 08 Jun 2018 12:15:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c1ee321d-d1d6-48af-8035-4ec20a83ebf0shibshab<p>You can find the documentation about the Eddystone example&nbsp;<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/ble_sdk_app_es.html?cp=4_0_0_4_1_2_9">here</a>.&nbsp;<br /><br />There is no API directly exposed for changing the advertised frame.
