Following on from getting CMRI / JMRI working over ethernet I thought I'd have a go at Wifi!

As explained in the video it was a little trickier and I didn't have a suitable Arduino board so used an ESP32 one. But the code shared below should be fully compatible with a Wifi enabled Arduino and does successfully compile for Arduino boards. The video includes a bit of a 'getting started' guide for ESP32s and the Arduino IDE.

The latest test release of JMRI, 5.3.6, includes the C/MRI bugfixes required to run this code, as listed in the release note https://www.jmri.org/releasenotes/jmr.... Download links are towards the bottom of this page.

The solution I came up with relies heavily on Michael Adams' ArduinoCMRI work

The code I used (hopefully I've remembered to remove my wireless key)
