Been learning how to use i2c under Micropython. I've figured most of it out, but I have a frustrating issue with reliably receiving the second temperature data byte from my temperature sensor. I've even lowered the i2c frequency down to 1KHz and I'm still not receiving the second data byte occasiona...

Sorry for the late reply, had an urgent matter to attend to. I took another shot at it a few minutes ago, and now everything works fine; it must have been something stupid on my part (guessing that I didn't tab over correctly for a line of code, or something similar.) I was trying out the first exam...

I've been trying to call a function from a file, having no luck I tried the example from the page: http://wiki.micropython.org/Importing-Modules But even with the example this is what I get: Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'module' object has no...

SUCCESS! After reading the reply on richarddavison's thread (https://forum.micropython.org/viewtopic.php?f=16&t=3665) , suggesting that the one that I have may have an ESP8285 chip. I tried the instructions provided in the linked thread(adding --flash_mode=dout) and success, I now get the REPL promp...

Nope, never found a solution. I did get a refund and ordered a replacement. Will see if that one will work.

I tried setting the UART speed to 74880 (and several over baud rates) to see if what I was getting at reset was actually something else other than garbage, but so far have had no luck. Balu, what firmware version worked for you?

I've been using the --verify option, and I've been getting verify OK every time.

I just checked it under the Arduino IDE and it verified the the flash size is 4MB. Are there any tools available to check if the flash is good/bad?

I did specify the baud speed (screen /dev/ttyUSB0 115200).

I have a WeMos D1 Mini V2 board. I'm able to erase the flash and upload firmware to it, but when I try to access it via serial, I get no repose. The best thing I can get is some garbage when I hit the reset button. This is my second board. The first board that I got about a month ago (same board fro...
