https://devzone.nordicsemi.com/f/nordic-q-a/113853/ble-gatt-statistic-somehowHello, currently tampering around with &quot;how to find out state of BLE TX FIFO&quot;, see e.g. Next idea: is there any way to access BLE transmission/reception statistics? So one could tell, that if there is a packet loss of e.g. 10%, the transmission FIFOen-USTelligent Community 13Tue, 27 Aug 2024 08:35:17 GMThttps://devzone.nordicsemi.com/thread/499917?ContentTypeID=1Tue, 27 Aug 2024 08:35:17 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f82533d-6ae1-4cb2-976d-aa279ebaba76Sigurd<p>Yes</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/499351?ContentTypeID=1Thu, 22 Aug 2024 10:59:55 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4e0346e-a589-4c69-b201-1c7c7f0a5cf0rgrr2<p>But the other event mentioned is catchable?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/499350?ContentTypeID=1Thu, 22 Aug 2024 10:55:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2dbcf901-cf14-411f-879c-a9c76a3bfd9dSigurd[quote user="Hardy"]I guess for my application is sdc_hci_event_number_of_completed_packets_t the way to go.&nbsp; Any examples on that?[/quote] <p>No... this e<span>vent is not supposed to be used directly by the Application layer.
