how to read and write in ble central and peripheral codehttps://devzone.nordicsemi.com/f/nordic-q-a/14179/how-to-read-and-write-in-ble-central-and-peripheral-codeHi all, I am trying to read and write in ble central and peripheral code with softdevice s130. Here i can able to connect to particular ble device with unique ble device id, here is their any possible to connect to other device without using ble deviceen-USTelligent Community 13Tue, 31 May 2016 10:14:36 GMTRE: how to read and write in ble central and peripheral codehttps://devzone.nordicsemi.com/thread/54177?ContentTypeID=1Tue, 31 May 2016 10:14:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3826695d-0647-4a6b-a6a7-6a15888c6dfaPetter Myhre<p>I&#39;m not sure what you mean by &quot;ble device id&quot;. Device address? But you don&#39;t have to use it. Usually a central connects by first starting a scan with sd_ble_gap_scan_start(), it will receive BLE_GAP_EVT_ADV_REPORT events, and the advertising data will be available. This is also illustrated in <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.api.v2.0.0/group___b_l_e___g_a_p___s_c_a_n___m_s_c.html?cp=3_6_2_1_0_2_1_3_11">this</a> MSC. It can examine the advertising data to determine if it wants to connect to the device or not. It can look for a device name, an UUID, and so on. If it is found, it can connect with sd_ble_gap_connect(). It is illustraded by <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s130.api.v2.0.0/group___b_l_e___g_a_p___c_e_n_t_r_a_l___c_o_n_n___m_s_c.html?cp=3_6_2_1_0_2_1_3_1">this</a> MSC.</p> <p>If the central performs a write operation, the peripheral will receive a BLE_GATTS_EVT_WRITE event.
