ESP-01 Turns off after Ardinu Rebuild

[Jim Edgell]

I accidentally erased my Ardino, successfully rebuilt and installed the Ardino. I have everything working again including the serial port, but now my ESP-01 WiFi card turns the Blue LED on and then immediately turns off every time I restart the Altair. 

Was there a setting I missed?

I believe the blue LED turns on when it's searching for a wifi connection and turns off when it's connected.  I'll give it a try when I get home from work.

You are correct, the ESP-01 was still connecting to my Wi-Fi. Looks like reimaging the Ardinu has no impact on the ESP-01 settings. Once connected, the blue LED goes out, just like you said.

I found it connected to my network under an IP address, it seems since I rebuilt the Ardinu, the altair.local is no longer working on my wifi. It was working prior to reimagine the Ardinu.

The ESP-01s has completely separate programming from the Arduino.  All it does is receive data from and send data to the Arduino.  How did you reprogram the Arduino - with the IDE, or by downloading and installing the .bin file from my website?  What pins are you connecting the ESP-01s to (D18/19, A6/7, or LED RX/TX)?
