• Operating System: MacOS

Settings in IDE

• Module: Nodemcu 1.0
• Flash Mode: dio
• Flash Size: 4MB (1M SPIFFS)

Problem Description

Keep getting exception 29 due to wdt reset when using wifi in sketches.

The board seems to be fine for non-wifi based sketches.

Have tested this with several basic wifi sketches and all fail after a few seconds.

I have searched through here and tried new firmware, erasing the flash in multiple ways (esptool and through Arduino IDE), using the latest Arduino IDE version, library updates etc but nothing seems to solve this.

Have used delay() in the sketches but that doesn't seen to solve this either. Even the example wifi sketches fail.

Any suggestions gratefully received and appreciated as I have come to the end of my knowledge and abilities after 3 days of trying to sort this out.

Does adding WiFi.mode(WIFI_STA); before WiFi.begin() change anything?

[SiESP]

Have added Wifi.mode(WIFI_STA); into the line above Wifi.begin() but now get a different exception 29 error:

Just out of curiosity, why don't you try flashing the WiFiScan.ino.bin I just compiled ( https://www.dropbox.com/s/1h37h96xl3cr1we/WiFiScan.ino.bin?dl=0 ) and seeing if it works? If it does, then it's probably a problem with your setup, since it works fine here on my end.

PS. I don't know how to flash a precompiled binary under Mac, but under Windows esptool.exe -vv -cd nodemcu -cb 921600 -cp COM3 -ca 0x00000 -cf WiFiScan.ino.bin should do the trick.

I can try - is this an Arduino sketch or binary or something? Apologies for my lack of knowledge.

To help me decipher the esptool cmd line instruction can you tell me what the -vv -cd -cd -cp -ca and -cf flags cover?

When I load firmware the cmd line looks like this esptool.py --port=/dev/cu.SLAB_USBtoUART write_flash -fm=dio -fs=32m 0x00000 ~/Downloads/nodemcu_float_0.9.6-dev_20150704.bin

I don't have esptool tool running on a Windows machine at the moment unfortunately.

[WereCatf]

It's the WiFiScan-sketch that I compiled, nothing fancier than that. Also, I don't know what the flags are, I just copied the command that the Arduino IDE uses to flash the binary after compiling it (You can see it by enabling the File->Preferences->Show verbose output during upload)

[SiESP]

Will check it out - if I can translate the flags from esptool.exe to esptool.py on the Mac I will give it a try.

Do I need the .bin file or can you send me the .ino sketch and I can upload that directly?

Apologies for my lack of knowledge!

wdt reset

Please help ASAP..!!!

Thanks.

[Pablo2048]

Yeah, another ignoring rules/policy (aka too lazy to read), but 'help me ASAP' guy :-( Did you at least try exception decoder?

[devyte]

Several fixes have gone in, especially into the lwip glue code, since this was opened. Is this issue still valid in latest git?

[ulisses-santos]

Hi guys!

I'm using esp8266 in my application like a server TCP, and when it received RST package of client TCP, it's resetting... I'm sending below the image of communication.

https://www.dropbox.com/s/5sec8a1kn358tv9/esp8266_resetting.PNG?dl=0

Why is it resetting?

Thanks very much

[devyte]

Closing due to age and lack of feedback.
