I am running mB version 1.0.5 with FW: 103.
Just tested my Wemos with my WTSLogger tutorial @ https://wiki.microblocks.fun/community_projects .
Everything worked OK. No problems.
There's been a lot of FW and release changes with microBlocks. Make sure your boards are up to date.
Some pointers (if you are aware of these, I apologize):
If you are using the browser version, open the control panel with shift-ctrl-i, or if you are on the desktop version look at the console display window (the other command.com window that opens up when you run it)
You don't have to STORE your app code on the devices under microBlocks. It happens automatically.
However, there are some cases where the board udate is very slow. So to make sure your device is updated with your code, click the STOP button in the IDE followed by Run and observe the display panel messages. They should be:
All tasks stopped
There has also been a lot behavior changes with the USB connection of the devices. Mainly to automate the process for the better. However, these auto attempts sometimes cause retry loops that seem to go on forever. Again watching the display panels mentioned above will be helpful to detect these if any.
Firmware updates are now handled automatically in the IDE with the help of auto-detection. However, sometimes it does not work depending on the board's internal condition. So it is best to force it via SETUP menu option "update firmware on board" and observe via display panels.
I hope these will help you get going.
