https://devzone.nordicsemi.com/f/nordic-q-a/69708/failure-in-ble-communication-above-10-meter-distanceHello Everyone, we are using Nordic&#39;s nRF52840 controller with SoftDevice S140 and the default Bootloader(C:\nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10056_ble) example code supplied with the SDK. The Nordic Device is used as a BLEen-USTelligent Community 13Wed, 23 Dec 2020 08:53:45 GMThttps://devzone.nordicsemi.com/thread/286415?ContentTypeID=1Wed, 23 Dec 2020 08:53:45 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fda2a4e5-d43e-4b0f-9c45-00ccd54474a5JONATHAN LL<p>Hi Sakib sorry for the slow response,&nbsp;<br />Due to holiday there is fewer at work so response might be slower then usual. We are back in full swing in week 1.&nbsp;<br /><br />I should have elaborated in the previous question but since you are using custom hardware are you having connection and range problems with other BLE applications, like the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/ble_sdk_app_blinky.html?cp=7_5_1_4_2_2_3">BLE Blinky application</a> ?<br />Or does the short range connection issue only happen with this application ?&nbsp;<br /><br />It would be nice to know it the range limitations is due to hardware issues like bad antenna matching or if it is a software issue.&nbsp;<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/286141?ContentTypeID=1Mon, 21 Dec 2020 18:18:39 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b8e71e33-e8e7-48fc-ab4b-6a9f0d935b1fsakib<p>We are using custom made hardware</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/286122?ContentTypeID=1Mon, 21 Dec 2020 16:28:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:676bfb12-20c5-4975-8dbd-5bf8cfe2cd85JONATHAN LL<p>Hi,<br /><br />Are you using custom HW or one of our development kits(DK)?<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
