Resolved by DJ Sures!
DJ, I can see the new ARC will be awesome! But, the transition is a little painful. In my Marks R2D2 project, it appears that the code I had written in Blockly on the mobile interface is no longer there. For instance, a simple command to play a sound via a pushbutton on the mobile interface was written in Blockly as a play sound statement with a file name.
In the new ARC environment, the Blockly code is gone and its appears as an XML file statement. When I tried to copy that statement over.... I get this pasted into this window... which kind of makes sense. However, none of my code for the button logic works in the mobile app or in the mobile app preview screen in ARC.

Also, i had a follow wall code segment in Blockly that now appears as a single line of xml - and its broken too.
Any idea how I can get this working again short of redoing my work? It seems the sensors I have on the robot are working and the controls for the head and wheels. So, its appears its all around the Blockly logic being busted.

Yes. I tried that one. It seems the sensor value overlays for the CPU temp, battery voltage, and the three ultrasonic sensors don't work in mobile - but show up in ARC when running on the PC. Lets say I wanted to change to an onboard computer. It would have to be pretty small to fit in the R2D2. I have a RPI 4 w/2GB. Can I interface with the onboard EZ-B via wifi or would I have to go to the board and solder a connection between the two?
Hi mstephens_42, Fully functional computers that run Windows 10 can now be real small and very powerful. One that DJ talks about and uses is the Up Board. It's the size of a credit card and comes with different options of memory and storage. The price range looks to be from 100 to 160 USD. DJ says the cheapest will hold Win 10 and ARC just fine. Anything more you need to get one with more storage. It also has 4x port USB2.0 on connectors, 2x port USB2.0 + 1x UART on header, 1x USB 3.0 OTG, 1x Gbit Ethernet (full speed), 1x DSI/eDP port, 1x Camera (MIPI-CSI), 1x HMDI, RTC. and a 40 pin GP Bus.
I'll let others help with how to interface with your RPI.
Here's a datasheet and the Up Board link:

David’s correct. I spoke about embedded computers in robots a number of years ago. But the technology was too slow and costly and large at the time. I predicted it would happen - just didn’t know when. The thing about the mobile app is it’s a dual development effort for us. We considered charging for the mobile app - but that still doesn’t cover nearly the amount of effort gone into it.
so the agreement with ezrobot was to provide three basic functionality of the app for their robots. And let power users embrace latte panda or intel up-board. I personally really dig the intel up board. The lowest cost option with 2gb ram and 16 ssd works great but it only has enough space for ARC and nothing else. I’ll do a live hack of setting it up if you guys want?
that being said, I did discover a bug in the mobile app with getting the temp and voltage as you brought to light. That means the update this week will include that fix. So, if that’s all you need then the mobile app will work.
but if you’re expecting to continue making your robot more awesome by using all of the real cool new controls being released weekly, you’d need ARC
One last unanswered part of the question - I have a EZB-V4 board in R2D2. Can I interface with the onboard EZ-B via wifi from an installed small computer or EZB-V4 board and solder a connection between the two? I am not sure If for now I want to buy another small computer. But, I will look at the RPI 4 2/2GB.
Thanks DJ, I'd love to see a Live Hack on the Up Board and how to control it from outside the robot.
Watched the UP board video, very impressive for $99.00 , I also would like to see you Live hack DJ :-)
I am happy he tried Debian Linux in his example,

Both android and iOS apps were submitted today with a fix for the trackbar - it'll also fix your getping(). Expect a few days before they're available to your mobile device.
