https://devzone.nordicsemi.com/f/nordic-q-a/80579/nrf52840-ble-collides-with-computer-bt-mouse-and-keyboardHi, Our product has the nRF52840 with onboard BLE antenna. As the BLE link is on and operated i.e. communicates with TWN pad the wireless Microsoft keyboard and mouse are barely functioning or throw characters on screen. TWN pad works in BLE 4.2en-USTelligent Community 13Wed, 13 Oct 2021 13:08:58 GMThttps://devzone.nordicsemi.com/thread/333954?ContentTypeID=1Wed, 13 Oct 2021 13:08:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:08989a62-d545-4de1-8a23-f15579ea2ec1ketiljo<p>BLE is using 37 channels when it&#39;s connected so there shouldn&#39;t be any collision on the same frequency that causes this. Do you have a dongle as the receiver for your pad? If so, what happens if you move it to another USB port or use a extension cable?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/333929?ContentTypeID=1Wed, 13 Oct 2021 12:13:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8008623a-d79d-46f6-b059-21da327a8132Tzion Priav<p>Hi,</p> <p>As the TWN pad or our&nbsp;product are disconnected the mouse and keyboard return to work normally.</p> <p>There are about&nbsp;40 channels on BLE, they probably both work on the same channel and both don&#39;t change it.</p> <p>Can this happen?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/333921?ContentTypeID=1Wed, 13 Oct 2021 12:02:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2f21f5aa-f51b-44e3-809f-64b68131600dketiljo<p>Why do you think the mouse and keyboard is BT? It&#39;s most probably BLE as well. So the two links should not interfere with each other like like this. Even a BT link and BLE link will happily live together. So there&#39;s something else that causes this. Remove any USB3.0 devices, try an extension cable for the dongle etc.&nbsp;</p><div style="clear:both;"></div>
