Missing MDNS.update() in update()

[willdurand]

Hi,

using the latest Arduino 2.5.0 library and any example from this library (e.g., the LED sketch), mDNS does not work anymore: no device can be reached via its <hostname>.local domain.

According to this comment, there should be a call to MDNS.update() in the loop() so this call should be added to https://github.com/mozilla-iot/webthing-arduino/blob/305860fdd3aba08914c4f5d2d82d17eadc9617e5/ESPWebThingAdapter.h#L74-L76.

If I add MDNS.update() in the loop() of the LED sketch, the device is reachable again (via ping w25.local). The LWIP version does not matter (I tried v2 and v1.4).

Thanks for bringing this up! I was wondering why we hadn't had an issue previously and reading through that issue was fascinating
