https://devzone.nordicsemi.com/f/nordic-q-a/68697/receiving-large-data-over-nusI want to receive more than 250 bytes over NUS ,presently i have receiving All Data but in parts of 20 bytes (i.e after receiving 20 bytes BLE_NUS_EVT_RX_DATA event is occures). what should i do to receive Large Data over NUS under just one BLE_NUS_EVT_RX_DATAen-USTelligent Community 13Tue, 24 Nov 2020 10:24:50 GMThttps://devzone.nordicsemi.com/thread/281494?ContentTypeID=1Tue, 24 Nov 2020 10:24:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:207c3b09-60fa-49be-812e-3c2631f60e7cNarendrasinh Dabhi<p>Thank you @Vidar.....</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/281446?ContentTypeID=1Tue, 24 Nov 2020 07:49:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:579a08fc-bd4d-48c0-a38c-31595343ca26Vidar Berg<p>The BLE_NUS_EVT_RX_DATA is raised when you receive a BLE packet from your client, and the maximum size of those packets are limited by the ATT_MTU size for your connection.You can read more about this here: <span class="item"><a title="Experimental: GATT Module" href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/lib_ble_gatt.html?cp=7_1_3_2_13">GATT Module.</a></span></p> <p>That said, our peripheral NUS example does support 244 byte packets by default, so I guess long MTU is not supported by your client as you are only receiving 20 bytes at a time. </p><div style="clear:both;"></div>
