advertising problem with samsung android 9 and beyond

hi all,
we have a device using GATT protocol over da14580 ble
until recently we had no problem with the advertisement of the device
but in the past few weeks we discovered that on samsung phones using android 9 our device appear as "unnamed" and on android 10 it doesn't appear at all
we tried to run the default sdk code on the ble (SDK 5.0.4\DA1458x_SDK\5.0.4\projects\target_apps\ble_examples\ble_app_profile\Keil_5\ble_app_profile), and it acts the same - the USER_DEVICE_NAME doesn't appear on search

LG G3 with Android 6 vs Samsung Galaxy S10e with Android 9 - LightBlue

Device:

DA14580

Hi NadavG,

The ble_app_profile includes the custom profile. Please try to change the UUID of the custom profile. In addition you will need to change the UUID in the advertising data as well. Follow theTutorial 2 : Adding Characteristics - Custom Proflle Creationtutorial for more information.

Thanks, PM_Dialog
