My Bad. I was going to post a problem then realized it was really an Arduino compile issue then instead of cancelling this empty post I hit post.

while I am here I do have a question. I am using a Cytron ESP8266 with Wroom. I get the following message when the Arduino starts: Failed to enable MUX. It does not seem to affect anything as it runs normally. Just wondered what it means and what is hidden behind it.

Well I Googled the error… and determining that it seems mostly Blynk related, I found the error reference in the Blynk ESP8266 libraries…


With led me to Google enableMUX() and to this…

Which basically refers to a IP MUX(multiple connection mode - TCP & UDP)… I think Blynk just uses TCP so probably nothing to worry about? :stuck_out_tongue:

Thanks. It seems that the error does not appear every time and does not effect the operation.

Thanks anyway it is good to know what is important and what not.
