- Tue Mar 10, 2015 10:57 pm #11763 I just bought two of the 01's on ebay and get the same behavior.
The blue light blinks and displays this every couple seconds:

@f¼8¤ÿZÿ¨¬:¡åúÈ@J?É€è
[Vendor:www.ai-thinker.com Version:0.9.2.4]

ready

I can configure it and issue commands, but only in between these reboots, making it impossible to write any sort of reliable sketch.
Is this how the device is supposed to work or could I have something wrong...or are the chips DOA?
Thanks!

No. this is not normal.

Try:

1.- reflash again.
2.- flash lua firmware
3.- RST to VCC

- Wed Mar 11, 2015 6:04 pm #11831 I guess we need to ask this of everyone: How are you powering the ESP?

If your power supply can't source enough current it could be causing the ESP to reset.

- Wed Mar 11, 2015 7:26 pm #11837 I've tried several power configs.
12v 1a adapter to the arduino, then use the 3.3v from it to power the module.

5v 1a to the breadboard, then use a logic level converter to bring down the voltage.

I also connected the 5v to a cheap little "power bar" I bought on ebay that brings it back down to 3.3v.

The rebooting happens with all of the configurations.
