Thanks for your help. I read further about RC Low Pass filters and ordered a $6 PWM to Analog board from Amazon that handles this.

ESP32 Wroom 32d are the boards I am using.

I am using Arduino to experiment around with creation of a PWM based signal on one ESP32, which I do have up and running. I am outputting .959vDC via ledcAttach/ledcWrite using PIN 12. When I put a multimeter on the output, I do get 0.959v DC. This is a ...

Excellent, thank you

I have multiple ESP32-Devkitc-V4 units. Is that board considered ESP32-C2, C3, ESP, ESP32-S2 or what? Need to know what chipset I have to know the limits of which AT command set and ESP-IDF that i can use.

Thanks

My ESP32 WROOM is no longer running the AT command project... and I haven't touched the code.

I can compile it and flash it fine, and when the ESP32 reboots, i get this, and the board will not respond to AT commands...

See below, looks like instead of running the AT command set, it is running ...

Still looking for an answer on this...

I installed the following:

ESP-IDF 4.4.1 offline installer.
in windows/apps it shows up to uninstall as 4.41.

when I compile the ESP-AT source, and run it on the ESP32, this is what I get when I run

AT+GMR

AT version:2.4.0.0(4c6eb5e - ESP32 - May 20 2022 03:11:58)
SDK version:v4.3.2-553 ...

Where do I adjust the baud rate that the ESP-AT uses (UART)?

I know there are 2 different sets of R/W - I am not talking about the actual ESP32 console - I am talking about changing the speed from 115,200 on the serial PINS that the ESP-AT code is using, down to 38400 or 57600.

I am working on the ESP-IDF with the ESP-AT command set.
I have an existing project (modified set of AT commands) that works/compiles and flashes fine.

I now want to embed 2 files into
\esp-idf\esp-at\main\interface\uart\ at_uart_task.c

These 2 files are an SSL file (.pem) and a binary file .hex ...

@dtaylor thank you very much. I will give that a try.
