Stand alone (Wifi) - Laptop, MARTY and Mobile (Android)
I've finally achieved being totally stand alone - meaning to take MARTY say to School and for my Daughter to show her the moves by loading the SCRATCH programs in the PDF and to use the Mobile Phone App to Calibrate and make MARTY move. Here's what will work: Current Windows 10 laptop with latest patches (DO NOT USE an old Windows XP laptop like what I tried to do originally as this will cause the laptop/Chrome NOT to find MARTY thru the Calibration url. I tried countless different combinations like changing gateway address to MARTY or to the laptop but this did not work. Use 'Bob the Reset' Button to reset the Wifi SSID name in MARTY and use the Android App to re-configure to the Mobile hotspot (e.g. MartyOptusWiFi) on your mobile phone with a password. Don't make the mistake I made by having no password and the Mobile App will not work. I thought I would make it easier for the daughter in case she had to debug the issues at school. Use Current Windows 10 laptop and connect to the mobile hotspot. Use MARTY to also connect to the mobile hotspot (using mobile App). Use mobile App to check the IP address of MARTY - you will see this under Scan for MARTY & it will return e.g. 192.168.1.102. Go to Laptop and open a command prompt window and type in 'ping 192.168.1.102' and it should return a response time - which means you can 'see' MARTY. Note: Even though my Windows XP could ping / see MARTY the Chrome browser could NOT pick up the ip address of MARTY. I even tried to ADD in the IP address but something (e.g. scanning algorithm) is doing something maybe not quite right / or it could be something else.
In the end I was able to use the Windows 10 to open SCRATCH and load a program from the C: drive and play it and MARTY would do his/her bit.<br> The Mobile phone MARTY App CANNOT return a IP address / cannot see MARTY with the MARTY App being on the same phone. My guess could be that the IP address of the phone is the external one from the Telco and not the 192.168.1.1 (e.g. gateway address). You can use the Windows 10 laptop and Chrome to Calibrate MARTY - as this does work well. However, in the end I was lucky to find a person who sold me his 3 year old 3G Wifi portable router which I used as the device to connect MARTY, Laptop and Mobile so I can see and control MARTY.
After spending all day yesterday and today I finally found the right combination.
