https://devzone.nordicsemi.com/f/nordic-q-a/36056/nrf52832---max-number-of-connections-to-mobile-deviceHi all, I have a NRF52DK acting as a peripheral and running the ble_app_uart example. I want to have bi-directional communication with a mobile device that is connected. My question is, how many more devices running the same ble_app_uart program canen-USTelligent Community 13Wed, 04 Jul 2018 07:15:19 GMThttps://devzone.nordicsemi.com/thread/138888?ContentTypeID=1Wed, 04 Jul 2018 07:15:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:88e666a4-acac-4a50-8250-27dd0df607b1bjorn-spockeli<p>Hi Kian,&nbsp;</p> <p>the number of concurrent connections supported by your mobile device will be determined by the BLE chipset and the Bluetooth Stack of your mobiled device. In terms of packet collisions I would not be worried as a Bluetooth Low Energy Central schedules its connections, i.e. it will communicate with one peripheral at the time sequentially, see&nbsp;<a title="Connection timing as a Central" href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.sds/dita/softdevices/s130/multilink_scheduling/central_connection_timing.html?cp=2_3_1_0_14_2">Connection timing as a Central</a>.&nbsp;</p> <p>The nRF52832 and the S132 v6.0.0 SoftDevice supports up-to 20 concurrent connections.</p> <p>Best regards</p> <p>Bjørn&nbsp;</p><div style="clear:both;"></div>
