Configue nRF52840 Dongle to receive 240Bytes notifications.https://devzone.nordicsemi.com/f/nordic-q-a/63428/configue-nrf52840-dongle-to-receive-240bytes-notificationsHi, I am using pc-ble-driver-4.1.1 to receive BLE peripheral Device 240 Bytes notifications. And I used &quot;pc-ble-driver-4.1.1\examples\heart_rate_collector&quot; as starting point. But &quot;heart_rate_collector&quot; can only receive 20Bytes notification.

Default MTU size is 23.</p> <p>In order to use larger MTU size, use SoftDevice version higher than 3 and change the code to use a higher MTU size than the mentioned defines (up to maximum 250.) That means where the code refers to the defines, you need to use the higher desired MTU value instead.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
