Re: 3 brand new ESP WROOM-32s all have no WiFi connectivity.....

You should use ESP32 dev module. WROVER is a different module which includes psram. Install the WiFI scan example, set your logging level to verbose. If the rssi levels seem very different from what you get on the other modules, that would indicate some manufacturing defect. Your response was very ...

3 brand new ESP WROOM-32s all have no WiFi connectivity.....

Hello, I was wondering what available troubleshooting is available to determine why an ESP processor is not connecting to a local area network. I have used ESP WROOM-32s for a couple years and they normally work without any issues. But I just received 3 new ones that look identical to my existing un...

Micro USB ports are not the same from one 8266 to another.

So I ordered one 8266 off the web at ebay and had no issues interfacing to it. I ordered another from a different vendor and the one that arrived looks identical except for the Micro USB C interface port. It is larger. Does anyone know the spec difference on these USB C micro/mini ports? I am going ...

[SOLVED] Arduino 1.8.19 compile error : ImportError: no module named serial [Raspberry Pi]

Using a Raspberry Pi platform I am getting a "no module named serial" error on compile of ESP32 sketch under 1.8.19 Arduino IDE. The Espressif library is installed. Does anyone know what causes this error generation or how to correct it? I have installed python3. Traceback (most recent call last): F...

I'm actually surprised you aren't getting division by zero errors.
You need to set the pinMode in your setup (or at the top of your loop).

Code: Select all

pinMode(39, INPUT);
Ibernstone,

I inadvertently failed to copy the void setup() into the original post. The pinMode is defined there.

Grove (Seeed Studio) temp sensor 101020015 compatibility issue

Evidently the ADC module w/ the ESP32 does not properly extrapolate the conversion algorithm offered by Seeed. The analog value displayed is always: -273.15; the last parameter used in the 1st line of the algorithm. Is there a workaround for this issue? #include <math.h> #define ONBOARD_LED 2 const...

Re: Desktop PC port not recognizing esp32 running under 1.8.19 Arduino IDE

Solved:

Modem Manager app running in Ubuntu Linux was "highjacking" tty port.

ESP32 sketch compile errors on Arduino IDE platform (Ubuntu Linux 20.04 LTS)

Hello,

Is there any reported issues on this forum related to compiling sketches for the ESP32 (WROOM-32) on the Arduino IDE 1.8.19 platform running on a Linux Ubuntu OS?

Simple sketches fail to compile without errors. Is this a library link problem possibly?

thanks,

Mister Ed
