@Override
            public void log(int level, String tag, String msg) {
                logger.log(level, tag, msg);
            }
Old method to set a custom logger implementation, set it to {@code null} to use default logcat logging.
It updates only the logger object. The rest of log settings remain unchanged.
<p>
Example how to forward logs to Timber:<br>

<code>
<pre>
RxBleLog.setLogger(new RxBleLog.Logger() {
   &#64;Override
   public void log(final int level, final String tag, final String msg) {
       Timber.tag(tag).log(level, msg);
   }
});
</pre>
</code>

@deprecated use {@link com.polidea.rxandroidble2.RxBleClient#updateLogOptions(LogOptions)}
