Requests new MTU (Maximum Transfer Unit). This is only supported on Android Lollipop or newer.
On older platforms the request will enqueue, but will fail to execute and
{@link #fail(FailCallback)} callback will be called.
The target device may reject requested value and set a smaller MTU.

@param mtu the new MTU. Acceptable values are &lt;23, 517&gt;.
@return The new request.
@deprecated Access to this method will change to package-only.
Use {@link BleManager#requestMtu(int)} instead.
