Re: Getting MAC Address of Devices NOT connected in your network

I believe this requires promiscuous mode, as you say. This is supported on the ESP8266 (and ESP32) hardware, but not available in MicroPython. It would appear this wouldn't be too hard to add though -- via esp_wifi_set_promiscuous() & esp_wifi_set_promiscuous_rx_cb(). Correct, I already use with ar...

URL string

How do I convert url string to string, example:

receive request:

Code: Select all

request = conn.recv(1024)
print(request)
result: %23%24%25%26%40%40
should be: #$%&@@

Re: wifi: bcn_timout,ap_probe_send_start

Weird errors on ESPx usually come from several sources. One is failing to close sockets when they are no longer used: you need to ensure this always happens, through every code path. Secondly internal buffers can overflow. This can happen if one peer puts data into a socket and the other fails to r...

wifi: bcn_timout,ap_probe_send_start

after some runtime code, socket, I get the following wifi error: bcn_timout, ap_probe_send_start, locking the ESP-32 also happens on the ESP-8266.

Is there a fix for this problem ???

Thanks

Re: Close Socket

I think this means that the other endpoint is rejecting the connection. I notice you're using a nonblocking socket. This raises at least two issues. As I understand it, SSL/TLS on nonblocking sockets is a very recent addition to MicroPython. It may or may not have issues. Secondly you can't just se...

Re: Close Socket

You have made your code hard to debug by trapping all exceptions and issuing a generic message. I would suggest at the very least getting it to issue something more meaningful so you can figure out why it's failing except Exception as e: print('Socket Except Error', e) responseBytes = None # pass T...

Close Socket

According to the sample code below, sending packet to a host on a given port, if socket error occurs, depending on the code, the socket will be closed and returns None. But when resending, always returns socket error, something wrong ??? def openSocket(host,port,send,buffer): try: _socket = socket.s...
