Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 105] ENOBUFS
Expected behaviour
No response
Observed behaviour
-
Connected to WIFI.
-
Already open 3 socket with FTP, TELNET, MQTT
All works
However, when I attempt to create an additional socket for testing purposes, I encounter an error: OSError: [Errno 105] ENOBUFS. Following this error, the WiFi functionality ceases to work.
Additional Information
Any guidance on how to resolve this issue would be greatly appreciated.
