Re: Is 55C~60C a safe operating temperature?

Ohh no, no problems at these temperatures. It is recommended to have a large ground plane for allowing dissipation. Also, please use a low CPU frequency of 80MHz and sleep modes when idle. But why are you getting such high temperature? It may be a hardware design issue, I can stream data 24/7 at 8 m...

Re: Store Smart Config ssid and password in WiFi NVS structure

Oops, you should be posting ESP32 questions on esp32.com

And as for the question, I tried to use WIFI_STORAGE_FLASH and store WiFi credentials to flash but that does not seem to be working for some reason. At least not reliably. I am using a custom WiFi event handler and not the IDF default one.

Re: at+ commands respond with error

The firmware is REALLY REALLY outdated. You need to have at least v.1.5.4, which is stable. Please check out the latest firmware at

To flash the firmware to ESP8266, you will find many tutorials online.

Re: ESP8266 NodeMCU v1.0: no response on USB-serial connection

You should probably update the firmware on ESP8266 module that you are using.
Also, please use a 3.3V USB-UART converter. 5V can damage the ESP8266!

Re: More softAPs at once

Are you using the latest SDK? I think there is a bug in the program or something?
I can set >10 ESPs to softAP mode in the same room.

Re: flash vendor ???

Where did you buy the WROOM-02 modules from? Can you send in a link for these two modules?

Re: 4MB Nor memory OTA reboot fail

There is a bug in the code it seems, maybe you are writing to an address where you should not, or something like that. The output .S file address contains the aseembly code. The error should be at address epc1=0x4010151f
