https://devzone.nordicsemi.com/f/nordic-q-a/2749/ble-out-of-bandHello Everybody! I have been working with BLE security and I have an issue with OOB setup. I&#39;m setting my nRF with the following: m_sec_params.timeout = 30; m_sec_params.bond = 1; m_sec_params.mitm = 0; m_sec_params.io_caps = BLE_GAP_IO_CAPS_NONE;en-USTelligent Community 13Thu, 26 Jun 2014 09:33:21 GMThttps://devzone.nordicsemi.com/thread/10652?ContentTypeID=1Thu, 26 Jun 2014 09:33:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4691b396-5f69-4077-808e-f9fefe567330David Edwin<p>I do not think Android supports setting up the device with OOB, you can use passkey or justworks. Try <code>m_sec_params.oob = 0;</code></p><div style="clear:both;"></div>
