I have been able to test my ESP32 app on a large number of phones and found that in many of them, the ESP32 does not show up in the phone's bluetooth. It has worked on these phones: Samsung S9, Samsung S6, iPhone S6+. But it has not worked on Samsung A32, Samsung A72, Xiaomi... and undoubtedly, many more.
ESP-IDF 4.3.1.
See attached for menu config bluetooth settings.
Is it relevant that BT_BLE_42_FEATURES_SUPPORTED = n or that BT_BLE_50_FEATURES_SUPPORTED = n? These are under the "Update RPA to controller" setting - so I don't thing so. Although I believe the A32 uses BT 5.0...
Can anyone offer some clarity around this?
