https://devzone.nordicsemi.com/f/nordic-q-a/5647/event-upon-connection-startHello, I have an application in which the available power is so extremely limited that the hardware cannot do anything else at the same time as conencting to a central. Therefore I need to abort all other activities when a central is trying to connecten-USTelligent Community 13Tue, 24 Feb 2015 10:34:09 GMThttps://devzone.nordicsemi.com/thread/19787?ContentTypeID=1Tue, 24 Feb 2015 10:34:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3d368f3c-92cc-4278-b4f2-c6f3721e68a4victor<p>Hi Hung,</p> <p>Thank you for the reply. I will take a better look at the Core Spec.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/19786?ContentTypeID=1Fri, 20 Feb 2015 10:03:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:516a2862-3ce1-49bd-abcb-473572132fbfHung Bui<p>Hi Victor,</p> <p>There is no handshaking or connection establishing procedure with BLE when a connection in starting. BLE_GAP_EVT_CONNECTED event occurs when the softdevice receive the connect request packet from central. Please have a look at section 4.5.4 Vol 6 Part B in Bluetooth Core Spec v4.2.</p> <p>And I think you should be aware that with the same interval, advertising consume more power than in connection, because we have to advertise in 3 channel when in connection we listen and transmit on 1 channel at a time.</p><div style="clear:both;"></div>
