-> Have you connected an external antenna to this module or using the on board PCB antenna?
-> Please note that if you are using on board PCB antenna ,you have to populate cap (C14) and Inductor (L1) as mentioned in the datasheet ( http://www.cypress.com/file/318881/download page#13).
For more info refer the thread- CYBLE-202007-EVAL disconnect frequently
I am using an external antenna, the same one which I have successfully used in the past while working with the module as a scanner.
I will try switching to the board on PCB antenna and see if there is any improvement.
If it was working perfectly with a Scanner Application, then ideally it would have worked with your Find Me example project as well.
How are you observing the Advertising packets? Are you using any Mobile App or using the similar BLE device as a Central/Client project for scanning the peripheral/server devices?
Kindly check with CySmart Mobile Android/iOS app or CySmart BLE-USB Dongle with CySmart PC Tool (if available with you ) and confirm.
