https://devzone.nordicsemi.com/f/nordic-q-a/20039/want-to-communicate-2-pca10040-dev-boardHi, I am trying to communicate to PCA10040 (nRF52) dev board to communicate. Basically i want to configure 1 board as Master another as slave, so master will initiate the connection to pair another dev board. Could you please help me to implementen-USTelligent Community 13Tue, 28 Feb 2017 08:42:59 GMThttps://devzone.nordicsemi.com/thread/77992?ContentTypeID=1Tue, 28 Feb 2017 08:42:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5df33b0f-0333-4e8f-bf09-d412e4702ef6J&#248;rgen Holmefjord<p>Hi,</p> <p>There are multiple examples in our SDK that you can use for this, depending on what information you want to communicate.</p> <ul> <li><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_nus_c.html?cp=4_0_1_4_2_0_2">Nordic UART Service Client</a> (central) and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_nus_eval.html?cp=4_0_1_4_2_2_18">UART/Serial Port Emulation over BLE</a> (peripheral) can be used for sending text strings from on device to the other.</li> <li><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_hrc.html?cp=4_0_1_4_2_0_0">BLE Heart Rate Collector Example</a> (central) and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_hrs.html?cp=4_0_1_4_2_2_8">Heart Rate Application</a> (peripheral) can be used for transmitting heart rate data from one device to the other.</li> <li><a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_blinky_c.html?cp=4_0_1_4_2_0_3">BLE Blinky Client Application</a> (central) and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_blinky.html?cp=4_0_1_4_2_2_19">BLE Blinky Application</a> (peripheral) can be used for controlling LEDs on the connected device.
