If set, requires that LE Secure Connections is used for read/write access, however this is only true when it is combined with other permissions, namely BT_GATT_PERM_READ_ENCRYPT/BT_GATT_PERM_READ_AUTHEN (for read) or BT_GATT_PERM_WRITE_ENCRYPT/BT_GATT_PERM_WRITE_AUTHEN (for write), if these additional permissions are not set (even in secure connections only mode) then the stack does not perform any permission checks on these characteristics and they can be freely written/read."

Si est\u00e1 configurado, requiere que se utilice LE Secure Connections para acceso de lectura/escritura; sin embargo, esto solo es cierto cuando se combina con otros permisos, a saber, BT_GATT_PERM_READ_ENCRYPT/BT_GATT_PERM_READ_AUTHEN (para lectura) o BT_GATT_PERM_WRITE_ENCRYPT/BT_GATT_PERM_WRITE_AUTHEN (para escritura), si estos permisos adicionales no est\u00e1n configurados (incluso en el modo de solo conexiones seguras), entonces la pila no realiza ninguna verificaci\u00f3n de permisos sobre estas caracter\u00edsticas y se pueden escribir/leer libremente."
