esphelper error No Answer to our Authentication

[SteveRMann]

I have several esp devices around the house, and the Arduino sketch is essentially similar except for the nodename and connectname. I can upload to any of them except one. In that case (a Sonoff Switch), I get this error: esphelper error No Answer to our Authentication

Early in my sketch I define the nodename:

define NODENAME "counter"

And in my setup()

  //espHelper
  myESP.OTA_enable();
  myESP.OTA_setPassword(NODENAME);
  myESP.OTA_setHostname(NODENAME);
  myESP.begin();

I am pretty certain that espHelper is running because I see the hostname in the IDE Port: dropdown, and with the correct IP.

I have two other Sonoff switches and they are also running the same code except NODENAME is different for each of them. I even tried loading 'counter.ino' through the com port on a different Sonoff Switch- same results. I restart the IDE and the node "counter" is in the Port list, but I still get the same error.

Any help you could offer would be appreciated.

Your code actually does

//espHelper myESP.OTA_enable(); myESP.OTA_setPassword("NODENAME"); - note the " here myESP.OTA_setHostname(NODENAME); myESP.begin();

So the OTA password is NODENAME, not counter

[SteveRMann]

Not the problem.  I quoted NODENAME in an attempt to make sure the problem wasn't in the #define, and forgot to unquote it before posting. Even with an explicit password, I still can't get this esp to load OTA.

Any other tips? Are there any IDE parameters that could affect this?

Thanks, Steve Mann

OK, just making sure. So, it's only an issue when the node name is "counter"?

[frownbreaker]

Just a quick question; the Sonoff unit it an ESP8266 based unit or an ESP8265?

I ask as I have several ESP2866 boards that OTA fine but I have one ESP8265 (Wemos D1 mini lite) that gives me an OTA Error. You say you only have one device with a problem with OTA the recent Sonoffs like the slampher v2 use the ESP8265.

I've just tried this:

My program that works fine OTA on

• A) Wemos D1 Mini -Based on ESP8266 4megs flash
• B) Wemos D1 Mini Lite - Based on ESP8265 1meg flash

The same code works fine on A) and fails on the B) "error No Answer to our Authentication" it might be a space issue as the ESP8265 only has 1mb of flash and OTA needs more space?

My program is small and uses 34%

Did you find a solution to this? I have a similar issue.

It works for multiple ESP8266 12E modules as well WeMos D1 and D1 mini without any problems. But it doesn't work on ESP8266 01.

I get: "Authenticating...FAIL 03:46:31 [ERROR]: No Answer to our Authentication"

[SteveRMann]

I haven't readdressed this specific problem- too many other irons in the fire. On the -01 you absolutely must be using the 1Mb model. OTA will not work on the original 512Kb model. Also, when compiling, you absolutely cannot use more than 49% or the RAM, or OTA just won't work.

[ghost]

Yeah, I figured it out eventually. My ESP 01s are apparently the 512k model.

Thanks for your reply!

[terrag42]

Thanks for your reply StevRMann and ghost! Incorrect flash size selection was my problem as well.
