after changing a lot of pin combinations, managed to find working one:

Hello, I have maded schema of two MCP23017 IO expanders, connected to I2C with 4.7K pullup resistors, tested it on ESP8266 with NodeMCU LUA, they work fine now decided to try them on one WT32 board. Hardware I2C pins are used here for intergrated LAN, so I decide to try software I2C after lot of fai...

Had to have a bit of a search: https://stackoverflow.com/questions/3432102/python-socket-connection-timeout maybe setdefaulttimeout(2.0) >>> help (socket) object <module 'usocket'> is of type module __name__ -- usocket __init__ -- <function> socket -- <class 'socket'> getaddrinfo -- <function> AF_I...

Something to try: import usocket sock = usocket.socket(usocket.AF_INET, usocket.SOCK_DGRAM) send_data = b'I am going to listen for 5 seconds' sock.settimeout(5) # this sets the listening time Works for me. Maybe try usocket then DGRAM might narrow the problem down. I'm actually using usocket (just ...

Hello, I'm writing a simple wget script, but when try to connect to non existing IP or device that is offline, sock.connect take too long to rease an error >>> import usocket as socket >>> sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) >>> sock.settimeout(2) >>> sock.connect(("192.168.4.2"...

I have changed the esp8266 board and can successful disable wireless now, guess something was happen to old one.
Still the fact that it stores wireless config every time when I initialize wireless is enough not to use micropython on esp8266, after all, writable memory life is limited.

nothing special, just tested to see what gonna happen:

bad part is when problem happen, I initialize AP and set it to disable (false), it do not turn off AP, that is not acceptable for me at this point. Guess gonna move to LUA again.

Not sure if I posted that in correct place, if not please point me where I should report this. In short I never used micropython on esp8266, so I give it a shot, going thru the basics, making some init script for wifi, etc. During testing them I realized, that once wifi Is set for AP mode, It always...

I tested with another device (wemos D1 mini) all files from filesystem are deleted, disconnect it from power source, connect it again and AP is up with last settings that it was configured, in additional, I create a STA_IF, and try to set .active(False) check and it was set to false, AP is still up,...
