Are debug log messages (BLE_HS_LOG) from the host stack currently implemented?

Discussed in #1168

From nimconfig.h:

/** @brief Un-comment to set the debug log messages level from the NimBLE host stack.\n
 *  Values: 0 = DEBUG, 1 = INFO, 2 = WARNING, 3 = ERROR, 4 = CRITICAL, 5+ = NONE\n
 *  Uses approx. 32kB of flash memory.
 */
// #define MYNEWT_VAL_BLE_HS_LOG_LVL 5

Just curious because uncommenting and setting it to 0 doesn't appear to do anything, unless there's another flag that is needed for it work?

When I originally looked into this, it seems like you'd have to add code to nimble_npl_os_log.h, located in src/nimble/porting/npl/freetos/include/nimble

There's an ifdef statement where the ESP_PLATFORM part is implemented and the non-ESP_PLATFORM is left unimplemented:

# else
#define BLE_NPL_LOG_IMPL(lvl) \
    static inline void _BLE_NPL_LOG_CAT(BLE_NPL_LOG_MODULE, _BLE_NPL_LOG_CAT(_, lvl))(const char *fmt, ...) { }
#endif
#endif  /* _NIMBLE_NPL_OS_LOG_H_ */

But I don't know if you're comfortable with modifying a file within the my-newt-NimBLE library.

Thanks, yes that file is in the porting layer which I'm happy to modify.
