<p>Many user issues can be avoided by checking if a function returned successfully, by either testing for true/false such as when calling <code><a class="el" href="class_nim_b_l_e_client.html#a27e53c3746bc2d20ea7cfcea1a123cbf" title="Connect to a BLE Server by address.">NimBLEClient::connect</a></code>, <br />
