https://devzone.nordicsemi.com/f/nordic-q-a/60880/pc-ble-driver-py-notifications-and-low-connection-interval-seems-to-failHi, I&#39;m developping some test suite for one of our ble products in development, and I&#39;m encountering some unexpected behavior using pc-ble-driver-py. The test I perfom is the following : - I use pc-ble-driver-py with a pc10040 devkit board.

Does it appear anywhere?</p> <p></p> <p>What is your peripheral? Is it an nRF DK running something? Does it have a log saying anything?</p><div style="clear:both;"></div>
