rtl_433_ESP VS arduino-esp32

Lilygo LORA + OpenMQTTGateway is the way. See https://hackaday.com/2023/01/13/arduino-library-brings-rtl_433-to-the-esp32/ and https://github.com/NorthernMan54/rtl_433_ESP

And this is my iot project https://github.com/NorthernMan54/rtl_433_ESP

Hi Insteon friends, I started to work on this in fear that this day might come and actually got decoding of Insteon rf packets working on an ESP32+CC1101. NorthernMan54 has ported rtl_433 to the ESP32 here: https://github.com/NorthernMan54/rtl_433_ESP, however due to limited memory on the ESP32 I had to merge in changes to some of the methods from https://github.com/obones/rtl_433. All of that said, the range of the CC1101 is really short so probably not a viable option (I know very little about RF, so maybe someone can optimize that?). After that I went down the path of using an RFM69HCW which should have better range and using RadioLib https://github.com/jgromes/RadioLib but ran out of time to dedicate to it. Hopefully someone with more RF knowledge can make this a reality. Happy to upload the code that I used for the CC1101.

A little googling sent be back to reddit, where I find u/NorthernMan5 is porting rtl_433 to ESP32. https://github.com/NorthernMan54/rtl_433_ESP

I thought I would share a little something I have been working on over the last few months, porting of the rtl_433 code base to run on a ESP32 device with CC1101 RF Transceiver module. Details of the library are here https://github.com/NorthernMan54/rtl_433_ESP

You could just buy ready-made ESP32 boards with an OV2640 camera built-in, then customize the example sketch from https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Camera/CameraWebServer to your liking.

Are you perhaps this poster? https://github.com/espressif/arduino-esp32/issues/5250 - asking that poster for the list I just asked for went nowhere and it was auto-closed.

I have 2 ESP32-S2-Saolo-1 's on hand. I am trying to do the example Wifi FTM code that can be found at the following repo: https://github.com/espressif/arduino-esp32/tree/master/libraries/WiFi/examples/FTM

That has not been my experience at all as a user. ESPHome is even easier than Arduino and I haven’t touched firmware code in years.

The price makes a huge difference when you have dozens of them operating which is trivial with a decent hydroponics and smarthome setup. I also have a dozen boards just sitting idle ready to be called up to replace a failed one or use for a new project because they’re so cheap.

Not to mention the Arduino core is supported officially by ESP32: https://github.com/espressif/arduino-esp32

Who actually uses Arduino in production? Everyone just uses modules (for ESP32) or rolls their own using the Arduino board as a reference.

They've done a good job of hiding the RTOS from you and making most sketches run fine without porting, but you're still running as a task under the RTOS, yielding between loop() calls[1]. This leads to mysterious timing issues if you aren't aware of it[2]

It doesn't appear that the Arduino core for the Renesas chip is using the RTOS, at least by default -- its main loop is literally doing while (1) { loop(); }, similar to how the AVR core works. [3, 4]
