General issue report

i was trying to run example code of ble_enp but it has few issues :

1. it starts as a gatt client and try to discover for nearby devices instead of being advertised to other devices so other devices can connect to it manually like mobile phone.

2. if i try to use "CONFIG_BLE_CONN_MGR_ROLE_BOTH=y" then it starts advertising itself but it gives errors about some characteristics. also when i try to give command which is given as example output in readme.md file it gives error "Invalid option".

board im using : esp32 devkitc
