ESP8266 Community Forum

Hello, and thanks in advance for any advice.

I haven't been able to get ESP8266BASIC running on my nodeMCU v1 module because every time I flash it knocks out wifi.

For example, I can flash nodeMCU and set up AP, STA, and APSTA (both), see them with Fing or a wifi scanner, and log into the AP. When I flash BASIC, I lose wifi. If I flash back to nodeMCU, wifi comes back with all the original settings are there. Also, strangely, if I do a format flash wifi comes back.

I am using the 4M images, and all flashes are reported as successful, although I have noticed the bytes reported to be less with the format flash.

I have spent quit e a bit of time flashing back and forth without success, and thought it was time to ask the community for help. Any ideas?

Thanks for your help,

Ian Cameron.

Did you follow the setup instructions? The wifi setup from when lua was loaded is not going to survive when basic is flashed.

Thank you for the reply.

Yes, I followed the instructions, and also those specific to the nodeMCU at viewtopic.php?f=40&t=6732

It's not the lua setup that is the problem, but the fact that there is no wifi at all, despite indications of a successful flash. Also, as I mentioned, if I then do a format flash, wifi returns with the previous setup.

I did see someone mention flashing the original AT software often "resuscitates" their ESP, so I will try that, but am open to any suggestions.

Thanks again,

Ian.

I am having a strange issue with the 4m module too. Try flashing with any of the other sizes and let me know if it changes.
