Hello,
I would like to load the sketch on my ESP-01 over wifi. I tried out the wifi upload example and read a few discussions about it. It is able to detect the board on wifi but cannot actually upload. I also followed the guide here: http://www.instructables.com/id/Upload-firmware-ESP8266-via-WiFi/?ALLSTEPS to upload it manually using the python script and this fails as well.

Has anyone successfully uploaded firmware onto ESP-01? :?:

Using Arduino IDE 1.6.8 on Windows 7.

AFAIK you need 1Mbit flash for OTA to work, most (all?) ESP-01 come with 512kb.

More recent ESP-01s have 1M. Not sure how to tell when you buy one but all of the black ones I have are 1M. OTA should be possible with one of these? - I've not tried it as I use the extra memory for SPIFFS.

OTA updates definitely work on esp-07's with 1M of flash, should work on 1M esp-01's but I don't have any to test with.
