Found the answer in another post. Set putty to no parity and no flow control and it worked.

I have written a program using Adafruit Huzza ESP8266 board and I want to port that to other boards with additional capabilities e.g. NodeLink. So I can flash the broads and they boot and load python as well. All this is visible in putty. But post that I am not able to communicate i.e. send any comm...

Thank you. I found the problem is not memory but something else. I am creating a new post for that. But your reply was very helpful.

Or is there a version that I can build as I am using only a small part of it. I am trying to use micropython with Linknode R4. Anybody who may ha...

Request you to please explain in detail how you are...

There is no execution of main.py then I send the 'main.py' us...
