Good point (and that was also the reason why I still haven’t tested it). I was specifically referring to the OP’s ESP-01 module, which does not include a USB-to-serial converter.

I probably misunderstood what you meant by “reconfigure”. What I’m saying is that you cannot use other pins than 1 and 3 for UART 0. However, you should indeed be able to use pins 1 and 3 for other purposes than UART 0. (If there is anything else to discuss, let’s continue in the other topic you ope...

I can’t test it right now, but from memory: You cannot reconfigure the pins of UART 0 because they are hardwired, however what you want to do should be possible using UART 1, which transmits on GPIO2 (and cannot receive). To switch the terminal output to a different UART, use uos.dupterm() . I2C and...

Unless you have a socket.py on your filesystem, there is no difference, they will both give you the same thing: MicroPython v1.11-8-g48dcbbe60 on 2019-05-29; ESP module with ESP8266 Type "help()" for more information. >>> import usocket >>> import socket >>> socket <module 'lwip'> >>> usocket <modul...

the main.py may be started but I cannot see any error messages while main.py is executed.

There must be something wrong here. You should see error messages or anything else printed to stdout on the serial output while main.py is running.

Many of the basic library modules (like machine ) are integrated in the firmware and do not need to be installed on the filesystem. Run help('modules') to see which. Additional libraries can be installed either using upip (which is built-in as well, if I remember correctly) or by copying them to the...

I presume MicroPython will work on any of these devices. Yes. They are all the same chip. The regular D1 mini has an ESP8266 with external 4 MB flash, not an ESP8285. I just see that there is a “D1 mini Lite” with an ESP8285 though. I am not familiar with that one. (There is also a “D1 mini Pro” wi...

Only slightly larger than an ESP-01 module, this is the smallest full-featured ESP8266 (actually, ESP8285 = ESP8266 + 1 MB flash) board I have: https://www.tindie.com/products/onehorse/esp8285-development-board/ For the ESP32, I would check out the TinyPICO: https://www.crowdsupply.com/unexpected-ma...

My program runs for about 10 seconds and goes into deep sleep for about 10 minutes, then repeats. It seems like the memory is getting fragmented from this behaviour. I would consider that unlikely. The wake from deep sleep is a reset, so you are starting with a fresh heap every time. Does micropyth...

Neither of you state what hardware you are using, so nobody can tell whether it’s something they are familiar with and could answer. You’d probably get a better chance at useful answers by posting in a board-specific forum rather than “General Discussion”.
