750ms to read sensors sounds like a lot. Can you give more details on that?

Hi I've tried putting in a small sleep in every loop.

But until I kill the main process running I can't access the webrepl.

I can only enter a password, it won't accept it

Please help me if you can

Have you actually tried it with a 20ms sleep?

It works here, and not only that. I have a picoweb application with 4 additional uasyncio tasks plus webrepl, utelnetserver and uftpd all running happily together on one ESP32. Are you sure that webrepl is being started? The setup normally just tacks the import and start() at the end of boot.py. If ...

According to the ESP32 Datasheet the maximum High Level input voltage is VDD+0.3V, which makes it 3.6V since the supply voltage is 3.3V. It is my understanding that this is the maximum input voltage no matter what the attenuation is. The attenuation only affects the range, in which the ADC will prod...

It appears that such a busy loop will block all the polling background services, like uftpd, utelnetserver and webrepl. Inserting a small sleep_ms into it will give them time to react: import utime while True: utime.sleep_ms(20) That said I haven't found a way to deliver a KeyboardInterrupt (^C) whe...

EPERM means you don't have permission to access something. My guess is that you need to run this as administrator. That is really just a guess as I never use Windows for any of this.

The usocket module perfectly supports bind((<IP>, <PORT>)). When using '0.0.0.0' (AKA INADDR_ANY) for IP, the server socket will accept connections on all active interfaces. To limit it to one specific interface you should obtain that IP address via WLAN.ifconfig() and use it in the bind() call. You...

Have you thought about incorporating the term.js of WebREPL into the website, served by the ESP32? That should give you a ready to use terminal.

BL007, FTP is a protocol. The File Transfer Protocol, to be specific. Having an FTP server on the device doesn't mean that the user has to fiddle with some separate FTP client program. There are FTP client libraries for pretty much every language and platform. Using them will become part of your end...

Hi, i am having the same problem wiht a STM32 NUCLEO-L432KC, were you able to solve it wiht pyborad.py? and by the way what IDE do you use for develop yours scripts for this board?

Another option to transfer files to boards that have a USB based REPL is ampy.
