https://devzone.nordicsemi.com/f/nordic-q-a/7388/evt-disconnected-advertising-time-outI am using ble-Shield with arduino UNO on one side and Android device on other side. Most of the times i am disconnected with this error code. Can someone please tell what is the reason?

When you setup the advertising parameters, you likely specify advertising interval and timeout:</p> <p>ble_gap_adv_params_t adv_params;</p> <pre><code>adv_params.interval = NON_CONNECTABLE_ADV_INTERVAL; adv_params.timeout = APP_CFG_NON_CONN_ADV_TIMEOUT; err_code = sd_ble_gap_adv_start(&amp;adv_params); </code></pre> <p>In result, after the defined interval you get the advertising timeout. You can restart it again if you want.</p> <p>Not sure why you get disconnected - can be a bad sw on either side or anything hw related like a bad antenna, noisy environment etc</p><div style="clear:both;"></div>
