Hi all,

Anyone seen anything like this?

Flashed 2 ESP-01's yesterday.
Both flashed fine & I configured them OK.

Put them on Static IP's:

192.168.XXX.184 & 184.

Responded to pings, I could access the Web interface etc.

Plugged 184 into a project & it wouldn't connect,
Which I identified as a low 3.3V issue.

Resolved that & it still didn't work, so presumed it got corrupted.

Plugged 185 in & it's OK.

Now I've re-flashed 184 successfully;
I can connect to it & access the interface on 192.168.4.1 & browse all the pages,
But it won't find Wifi Access points, & it's spitting strange data out the serial port.

This is what I see when I connect to the port at 115200.

Flashed these 2 latest ones with esp-link-v2.2.3
Any thoughts on what it might be.

Cheers

Phil

Should also add that it flashes fine with ESPBasic,

And have re-flashed it since the above post;
Can still access it's web page on 192.168.4.1,

But it still won't find my access points.

What it's spitting out the port is a bit different now;
Basically the same, but minus the corruption seen above.

Does it sound like it might be a dud module with faulty flash?

Thanks.
