https://devzone.nordicsemi.com/f/nordic-q-a/96013/throughput-issue-with-qt-application-using-pc-ble-driverHi, I am using an device with an nRF52810 as a peripheral and my Windows 10 PC with an nRF52840 Dongle as the central. I am using a QT Application that uses the pc-ble-driver/python wrapper to download data stored in external flash off the deviceen-USTelligent Community 13Wed, 25 Jan 2023 14:13:30 GMThttps://devzone.nordicsemi.com/thread/406482?ContentTypeID=1Wed, 25 Jan 2023 14:13:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:adb3652f-5eab-4045-8796-a0042c410d7cSimonr<p>To use, compile and program applications with the pc-ble-driver you need to download the entire repository, not just part of it:&nbsp;<a href="https://github.com/NordicSemiconductor/pc-ble-driver">https://github.com/NordicSemiconductor/pc-ble-driver</a>. After doing so, we have readme files on hot to <a href="https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/README.md#Compiling-connectivity-hex-files">compile the connectivity hex files</a>, and <a href="https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/README.md#Programming-connectivity-hex-files">program connectivity hex files</a>. There is also a note in the latter desribing how to specifically use USB based kits like the nRF52840 Dongle.&nbsp;</p> <p>We also have some patches for the connectivity firmware here. I think <a href="https://github.com/NordicSemiconductor/pc-ble-driver/blob/master/hex/nRF5_SDK_15.3.0_connectivity.patch">the one for SDK v15.3.0</a> fixes your notification issues, where the device would reset when getting a high number of notifications.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
