Getting broken pipe connection refused error on creating continuous connection with device and sending commands

Configuration

@fabaff, @gpbenton:

I wrote a custom component script.

Getting broken pipe connection refused error on creating continuous connection with device and sending commands using this script.

Can you tell me what might be the reason for this?

Can you please stop to tag people for every post you create?

No, I can’t because there are no details. First guess the device is buggy, second guess the code is buggy.
