Right now the current logging system lacks debug level and something like tags (it could be an arbitrary string).

The callback would look like that:

void modem_log_handler(void *user_data, char* tag, enum log_level log_level, const char *msg)
{
    /* Up to the application to handle it */
}

The tag could be used to filter out parts of the logs, like booting for instance. For example:

void modem_log_handler(void *user_data, char* tag, enum log_level log_level, const char *msg)
{
    // todo: handle all the cases
    if (strcmp("Boot", tag)) {
         // handle all non boot messages
    }
}
