https://devzone.nordicsemi.com/f/nordic-q-a/54140/any-ideas-for-designing-a-ble-repeaterWe are designing BLE products based on the Nordic nRF52840 chipset and star network topology which are used indoors, according to the network structure, we use one Master Unit and max. 19 slave devices in one network. After those devices are paired togetheren-USTelligent Community 13Wed, 14 Jan 2026 08:39:46 GMThttps://devzone.nordicsemi.com/thread/558666?ContentTypeID=1Wed, 14 Jan 2026 08:39:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6041bfae-6b56-41da-b215-75799b74a5c1Ziga Miklosic<p>Are there any off the shelf products that can do that? So that can simple relay/repeate all the BLE packets?&nbsp;</p> <p>We are thinking into the same directions, as having problem with indoor range limitations, but want to avoid the development time and cost.&nbsp;<br /><br /><a href="https://devzone.nordicsemi.com/members/nordic-qa">Nordic QA</a>&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/219164?ContentTypeID=1Thu, 07 Nov 2019 19:48:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f964dae6-08f8-40e1-b94b-f600a7a87211Sigurd<p>Hi,</p> <p>1) Yes, it&#39;s feasible.</p> <p>2) A nRF52840 can act concurrently as both master and slave, so you only need 1 nRF52840 for the relay/repeater.&nbsp;We<span>&nbsp;have a relay example in the nRF5 SDK. See&nbsp;</span><a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_rscs_relay.html?cp=5_1_4_2_1_2">this link.</a></p> <p>3) Another option could be to&nbsp;use a mesh network instead,&nbsp;e.g. with Bluetooth Mesh, Zigbee or Thread.</p><div style="clear:both;"></div>
