Re: New Lolin D32 Pro with 4MB PSRAM
The D32 does not have an onboard MicroSD slot. The new D32 Pro does. It's one of those half height ones, like on the pyboard. You can still connect an external MicroSD board to the D32. The wiki page is up now: https://wiki.wemos.cc/products:d32:d32_pro Thanks for clearing that up - I literally jus...

Re: New Lolin D32 Pro with 4MB PSRAM
Does the D32 have a microSD slot? That would be a super useful feature for me! I hope there is some improvement with the battery drain in deep sleep.
Edit: yes it is, sweet! This could be an awesome board for remote data logging! I've been keen to try out Micropython for data logging.

Re: how to generate some test traffic?
Ok I think this has helped: http://docs.micropython.org/en/v1.9.2/e ... k_tcp.html
But some "explain like I am five" would still be appreciated!

how to generate some test traffic?
Hello ladies and gents - I have a basic sensor monitoring system I am running on a ESP32 using Micropython and MQTT - It is working well at home. I have tried running it at the Uni I am based at but I get an EHOSTUNREACH error. It looks like I am getting blocked for some reason by the network here. ...

Re: MicroPython As A First Lanuguage
I am no expert, but I would say by learning micropython you will have transferable skills for microcontroller programming in general. I've been working with Arduino for a lot longer, and Raspberry Pi in more recent years - I'm pretty new to Micropython but it's been a piece of cake so far as I gener...

Re: ESP32 power conditioning
The firmware has a brownout detector, I think it shuts things down when voltage drops below a critical value, but I was seeing some odd behavior in my experiments where the filesystem could get corrupted before that happens. Reads would result in bad data, and on several occasions I had to reflash ...

Re: Question about 3v3 pin and Deep Sleep
I guess in the circumstances it happens I could just as easily do that with a jumper wire

Re: Code editor
Thanx, will test it out. My bad, did not state OS I use. I use Windows 10 x64 (have another pc with W10 x32). I have Raspberry Pi3 with Raspbian , so I connect with Putty from Windows. Then ESP32 is connected to Rpi3 via usb cable. I run command "rshell --buffer-size=30 -p /dev/ttyUSB0 " to connect...

Re: ESP32 power conditioning
cause, reason = machine.wake_reason() if cause == 3: # woke from deep sleep # do stuff machine.deepsleep(5000) elif cause == 6: # soft reset # do other stuff This is a useful snippit, thanks! - I've just got a "debug" pin on my setup at the moment, pull low to prevent loop.

Re: Question about 3v3 pin and Deep Sleep
I have had the ENOMEM error a couple of times using MQTT - it happen's occasionally when the board only has a soft reset and then I try running the code again, and seems to get triggered by a particular line in the MQTT module. It's a bit too deep for my level of understanding but from looking at so...
