Please define unit for smtc_modem_hal_get_battery_level

[disk91]

The documentation says:

/**
 * @brief Return the battery level
 *
 * @return uint8_t Battery level for lorawan stack
 */
uint8_t smtc_modem_hal_get_battery_level( void );
``` 

What is the unit ? assuming not Volt and not mVolt in an uint8. What can it be ? %age ?

Hi,
It is compliant with the battery level defined in the LoRaWAN specification.

This is documented in line 440 of "smtc_modem_hal.c"
This will be moved to the *.h for the next coming release.
Many thanks,
Best regards
