Hi, I have a scenario where I use AP, WiFi STA and ethernet STA. I have several network services: - Webserver, active on all interfaces - MQTT, which I would like to activate exclusively on an STA interface - PING session active on the gateway of the ethernet interface (the switch is in my card, so ...

Hi all I tried different methods for compile my .proto files, but every time there is something wrong. This solution ( https://github.com/nopnop2002/esp-idf-protocol-buffer ) is only for Linux, and it doesn't create the source files but only use them. This solution ( https://github.com/MarcGeh/esp32...

That'd be about 50k/2=25kOhms, which is definitely larger than the 2-10k normally used. Thanks Microcontroller. The devices communicated for a while, and for that i was thinking that the internal pullups was enough and the problem was the firmware implementation. Moreover, i was able to see the mas...

I have 2 ESP32S3, and they need communicate by I2C (all my uart are busy). Master sends a stream (i can see it and I2C decode by oscilloscope) but the slave seems doesn't receive nothing. For double check, i tried inputs and also i tried to start a I2C master communication on the slave one, only for...

Hi, I'm using esp-idf v5.0. I already get file via HTTPS like in "https_mbedtls" example, without embed a PEM file. It works well, but for other connections (for example, for the OTA procedure) the library needs the PEM file. I wouldn't like use embedded PEM, is there a method to get the PEM file fr...

I would like to know too...
Moreover, can we start a webserver in the second stage bootloader (and freertos, too...)?

Thanks for the reply. I hope it can be resolved quickly, also because otherwise we risk creating posts that have already been proposed in the past. Realistically we don't scroll through 36k posts before asking a new question...

Search function of this forum returns HTTP error 500 (internal server error), so it is unusable. Moreover, is there a symbol legend for the posts tags? What means if there is a gray icon with a little yellow corner? And when read the post, what means if there is a little green flash in the upper rig...

I’m trying to override 2nd stage bootlaoder. For that, i simply create a new IDF project, and load the sample “custom_bootloader”-“bootloader_override”. Now, i correctly build the project and download it. As said here the 2nd stage bootloader should be resides at offset 0x1000 in flash, but flash_ar...

The hardware developer read this post: https://esp32.com/viewtopic.php?t=1654 So he decided to cable the SPI bus to the reserved pins for drive a W5500. In detail, he used 37 as MISO 35 as MOSI 36 as SCK The W5500 works well with other pins, but when I tried to move SPI3_HOST on that pins, nothing w...
