Re: ntpclient - uasyncio based NTP synchronization
Sorry for the delay, had limited time for a while and hobbies had to take a back seat. Hello, 1. i use ntpclient in my esp8266 board, Why do the following errors occur? Traceback (most recent call last): File "uasyncio/core.py", line 1, in run_until_complete File "ntpclient_base.py", line 120, in _a...

Re: IR transmitter/receiver
On a side note, by try and error I found that a lot of devices have IR functions, that are not available from their original remotes. Like dedicated power on/off signals, where the remote can only send the power toggle signal. This means that if you can only use a remote "learn & repeat" system in o...

Re: unable to access webrepl when main script is running
750ms to read sensors sounds like a lot. Can you give more details on that?

Re: unable to access webrepl when main script is running
Have you actually tried it with a 20ms sleep?

Re: Asyncio and WebREPL
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 ...

Re: (ADC) Unclear: Attenuation changes the physical or the digital range of the ADC?
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...

Re: unable to access webrepl when main script is running
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...

Re: [NUCLEO-L476RG] How to compile main.py and send to board
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.

Re: Bind with Ethernet Port Only
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...
