https://devzone.nordicsemi.com/f/nordic-q-a/85734/ble-advertising-of-custom-servicesHello, I am developing an application that requires advertising of multiple custom service over BLE. I have successfully implemented the custom services, assigning a custom 128-bit UUID . I encountered some issues when starting the advertising ofen-USTelligent Community 13Thu, 17 Mar 2022 07:34:09 GMThttps://devzone.nordicsemi.com/thread/358534?ContentTypeID=1Thu, 17 Mar 2022 07:34:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dc0bf341-6e5b-443b-a47c-807723fea75fkalpino<p>Hello Simonr,</p> <p>I solved by problem by allowing just a subset of services to be advertised, while making the rest of services available once the device is connected.</p> <p>Thanks for your support!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/357952?ContentTypeID=1Mon, 14 Mar 2022 13:02:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a48ec8d0-d4ae-4eae-a998-24e61b4dcf40Simonr<p>Hi</p> <p>Indeed, extended advertising does not support being both scannable and connectable. How many custom services do you plan on adding exactly? You won&#39;t be able to fit more than two in a regular CONNECTABLE and SCANNABLE advertisement with scan responses. Is it necessary to advertise multiple custom UUIDs or is it fine to advertise one, and do discovery of the rest once connected?&nbsp;</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
