Issue with ESP01 - No Access point available

[juancgalvez]

Hi Martin.

Thank you for your excellent software.

I have it in a Wemos D1 Mini and it works great with some IoT devices that I have far from my main router. Absolutelly stable.

Recently I found some old ESP-01 with 512KB memory and flashed esp_wifi_repeater into them. None worked. I can get access it via serial console, but there is no AP available to connect to.

This is the erasing and flashing result:

After flashing I reset it and get this:

Starting Web Config Server on port 80

bcn 100

If via serial console I send the command show config, I get this:

show config

But, Is mentioned before, no MyAP access point is available to connect to.

If I manually configure ssid, password, device static IP, netmask, Gateway then save configuration and reset I get this:

I am using the latest firmware up to date downloaded from github.

What could I be doing wrong?

[martin-ger]

Very strange - if you go back to an older fw, let's say beginning of this year. Better?

[juancgalvez]

Martin.

Thank you for your fast reply.

I tried several esp_wifi_repeater versions:

2019-01-20
2018-11-08 (Keeps resetting)
2018-11-26
2018-06-24 (Uses 0x00000 and 0x10000)

And none of them worked.

Thinking it could be an issue with de ESP-01 I flashed DNSServer -> CaptivePortal demo for ESP8266 in Arduino IDE and it worked flawlessly. My computer sees it's AP, can connect and get a response from it.

[juancgalvez]

Sorry for closing the thread. I think I did something wrong. I am reopening it.

[juancgalvez]

Could the problem be related to the fact that the device has only 512KB?

[juancgalvez]

Hi Martin.

May I expect some additional reply from you?

Thank you.

[martin-ger]

Short reply: I don't know. Please remember: this is my spare time project and it is free to anybody, so don't expect 24/7 support! Also, thousands of users have installed this successfully in the last years. So it is know to work in many environments. And it is known to work with ESP-01 - even the latest version runs for me.

Think my ESP-01 has 1 MB, so 512 might be the issue. You might try to go back to this version, it was before rboot. This should definitly fit into 512 KB.

Hi Martin.

Excuse me. I didn't want to bother you. I just tought you were looking at something. I understand you are doing it for free to help people like me.

I tried the versión you told me, and it showed the AP and I was able to connect to it a configure. But, once configured it kept disconnecting from the router almost every 5 seconds. Disconnect reason was 34.

I thing I am going to give up with these ESP-01 512KB devices.

Thank you for your great firmware and help.

Hi Juanc,

I´ve been stuck at the same point for 1 month, and I still am. I' working with with NodeMCU, it has 4 MB. Now I'm busy with another matters but still thiniking about it. I've even thought that the problem might be my router, but I don't know what should be the next step to take. I'll try giving it a fixed IP adress, Just to try something. It's a shame that we can't take advantage of so much good work. I haven't quit yet.

Hi Txemin, I flashed the latest firmware to a Sonoff Dual Vers. 1 and to an ESP8266-01 with 1MB size, both worked right from start as designed. Absolutely no issues with flashing, getting started and using the devices. No restarts so far, but currently only 2.5 days after installation.

Best Regards Gisbert

Thank you very much. At the end I didn't need to do it. After changing power unit, and learning port forwarding it's working.
