https://devzone.nordicsemi.com/f/nordic-q-a/21079/being-discovered-service-using-milti-link-peripheralHi. i&#39;m using nRF52832, SDK13, S132v4 as multi-link peripheral. As I know, SDK13 supports multi-link peripheral refering to example &quot;experimental_ble_app_multiperipheral&quot;. But as I tested, when 1 central is connected, other centrals can make connectionsen-USTelligent Community 13Tue, 04 Apr 2017 13:25:08 GMThttps://devzone.nordicsemi.com/thread/82360?ContentTypeID=1Tue, 04 Apr 2017 13:25:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:85fb5262-e834-4eee-91d3-6de53acb279eSigurd<p>Hi,</p> <p>It should not be necessary to change anything in nrf_ble_gatt.h. The peripheral link count is defined in main.c as <code>#define PERIPHERAL_LINK_COUNT 4</code> (line 69). I just tested the example by connecting 2 centrals, and it worked fine.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/82359?ContentTypeID=1Tue, 04 Apr 2017 00:17:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:231081d2-9cb6-4127-9faf-ede2e80ca24droger.k<p>I think I got the solution by myself. I changed nrf_ble_gatt.h as below.</p> <p>#ifndef NRF_BLE_CENTRAL_LINK_COUNT #define NRF_BLE_CENTRAL_LINK_COUNT 0 #endif</p> <p>#ifndef NRF_BLE_PERIPHERAL_LINK_COUNT #define NRF_BLE_PERIPHERAL_LINK_COUNT 8 #endif</p> <p>#define NRF_BLE_GATT_LINK_COUNT (NRF_BLE_PERIPHERAL_LINK_COUNT + NRF_BLE_CENTRAL_LINK_COUNT)</p> <p>NRF_BLE_CENTRAL_LINK_COUNT was 1 and NRF_BLE_PERIPHERAL_LINK_COUNT was also 1.</p> <p>So I think we have to change this values to use multi-link. Is it right?</p> <p>I hope your reply.</p><div style="clear:both;"></div>
