Many bugs and problems. Please help!

#1

I’m facing many problems with the 2 mBots I got from the Kickstarter project. We have the 2.4Ghz version.
I did a firmware update (at least I think I did - it went from 0 to 100% and message box said update completed). I also tried to reset default program and installed the Arduino driver. I am using the latest version - 2.2.0.07.23.001

There are still many problems:

  1. I can’t connect the iphone app. I can’t find the robot on the list to connect to.
  2. Many programs don’t work as expected. Some examples:
    • Using ‘play note’ option plays different note duration every time the program tuns.
    • The 'repeat until option isn’t stopping the program.
    • Sometimes the programs end unexpectedly and won’t run again. Only ‘reset’ helps.
    • The new drawing option (on the led lights) seems to work incorrectly - the two right most light columns are always on and the drawings don’t change as expected if I use more than one drawing in the software. Only reset removes the lights.

These are just some of the issues. Am I missing anything? Maybe the firmware wasn’t updated as I thought it was? How can I check this?

Any ideas will be welcomed.

Thanks!

For #1 you will need the bluetooth module for mBot to connect it to your iPhone.

I had the same issue with the drawing display on the LED panel when connected with the 2.4 Ghz option. If you connect via the USB cable it will look fine so I think it is a bug in mBlock somewhere. If you send the drawing to the mBot as an mBot program it should also work ok.

You must be connected via USB to upload Arduino code by the way, a 2.4g serial connect does not let you send over the program.

Which repeat until loop are you using?

Thanks @Trapsis and @IrishClanger.

I didn’t know that only Bluetooth model works with the iphone, (but it makes sense). Is there a way to convert 2.4 to bluetooth?

As for the LED bug - I had a feeling it was a bug. I’ll try the USB cable. Maybe it will fix other things too.

Thanks. If anyone has any other tips / ideas please let me know.

This is what you need: http://www.makeblock.cc/bluetooth-module-for-mbot/

seems you need to use USB for actually saving firmware and saving programs to the mBot
You can use the bluetooth or wifi to communicate between mBots and mBot to computer/mobile device
There are a few quirks and some do get resolved with firmware and mBlock updates but some persist. Patience and this forum is your friend in these matters since this is still all fairly unpolished stuff. I still love it but it does get frustrating.
