Hello
Could you help us describe your setup and modifications implemented, to try replicate the scenario please? Also, it would be very helpful if you could provide
[Modifications in Code, SDK version, Log, If you are using EVKs or Custom boards with KW45]
If you use the code without modifications from the SDK for eatt peripheral, does it work correctly? You can see information on this example in Bluetooth Low Energy Demo Applications User’s Guide Chapter 5.4 and 5.5
Best Regards
Luis
