PRI 3 B device doesn't receive notifications from NRF52 DK

Hi, I used NRF52 DK and NRF Connect SDK 1.6. I used the st_ble_sensor sample with no changes. When I press Button 1, I expect to get a notification on the central device. The nRF connect app for Andorid works as expected. BTool (TI's BLE Tool for Windows with a dogle) also works as expected. However, RPI 3 B, can connect to the device, enable the notifications, but the notifications aren't received.

The RPI is a BLE 4.1 device. Could it be that NRF52, being a BLE 5.2 device sends notifications that RPI doesn't understand?

Turns out that the sample called  st_ble_sensor doesn't work correctly.  I do see a notification in BTool, but not in nRF Connect Android app. I switched to a different sample called peripheral_lbs which does the same thing and works like a charm
