https://devzone.nordicsemi.com/f/nordic-q-a/105362/delay-response-of-gatt-read-requestHi. I am relatively new to ble development and have a problem where I have a nRF52840 board, using the Zephyr bluetooth LE controller, that acts as a central to 2 other connected devices via ble. I would like a user to able to connect to the 52480en-USTelligent Community 13Mon, 06 Nov 2023 13:35:53 GMThttps://devzone.nordicsemi.com/thread/454218?ContentTypeID=1Mon, 06 Nov 2023 13:35:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0981fb03-1e0f-4540-925f-be8b663d98f8AHaug<p>Hi,</p> <p>I would recommend that you reach out to the Zephyr forum regarding the Zephyr BLE controller. You can find their support forums on Discord through&nbsp;<a href="https://www.zephyrproject.org/">https://www.zephyrproject.org/</a>&nbsp;&nbsp;<br /><br /><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/0535.pastedimage1699277713461v1.png" alt=" " /><br />I would also recommend you to go through the BLE fundamentals course at&nbsp;<a href="https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/">https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/</a>&nbsp;but do note that this course uses the qualified Softdevice BLE controller (Nordic Semiconductor solution) instead of the Zephyr controller</p> <p>Kind regards,<br />Andreas</p><div style="clear:both;"></div>
