Unable to connect app to any Mbots or Makebots


#1

I have a classroom set of the new Acer Tab 10 Chromebooks which run android apps and about 50 makebots of all different types.
In trying to connect any of the robots, the chromebooks throw up a “Device nor supported, or firmware not detected” error, or instructions to update the firmware.
I’ve updated the firmware on each type of bots, updated the android app to 3.1.9, but the error persists.
The bots work just fine on a set of borrowed older android tablets, and on new iPads running 3.1.9 , just not on this type of tablet, which I’m locked into using for my classes! Help!

(Will the 3.2.0 update help with this? Also, why is 3.2.0 only available for iPads?)

Have you tried to update firmware or reset default program in mBlock (PC software)?
When you try to connect Bluetooth it says “device not supported”? Can you take a screen shot of that page for me?
What robot you tried? mBot, Ranger?
And Android 3.2.0 version is still improving and it will be available soon in Google Play Store.

Thank you for your reply.
I have updated the firmware using the PC version of the program several times, with no effect, and reset the default program several times as well.
I’ve attached the screenshot below.
This particular one is for the mBot, but I’ve attempted with the mBot, Ranger, Ultimate 2.0, and the Starter. (I work for an organization which purchased a large number of these for our programming, so I’ve tried it with several different robots of each model, with no success.)

I have also attached a screenshot of the error in the mblock app, which gives a slightly different error.

Makeblock App supports mBot, Ranger, Ultimate/Starter, Ultimate 2.0. If you got the second picture, reset default program should help. If it is not, please keep USB serial disconnected, keep all RJ25 ports unplugged, change new battery, then try again.
The first picture should happen to mBlock Blockly App which only supports mBot and Ranger. When use Ranger, please click on “create” first and then connect Bluetooth, then it will detect it as Ranger. If your device is Ultimate, you may see the error as the first picture.
