Problems connecting BLE with last purchased ESP32

[jexcobar]

Hi all, We have been using hundreds of ESP32 Devkit V1 boards in a device using a BLE connection for several years now. For more than a month the latest units of ESP32 Devkit V1 acquired, give BLE connection failures with any android app, even loading their own examples in Arduino as "BLE_notify.ino". Is it due to the ESP32 upgrade to BLE 5.0? Can someone provide some information?

Thank you and greetings.
