Re: Icmp time exceeded on route when replying to modbus tcp

Hi I am using ESP32 with modbus tcp to connect from ESP32 as a slave to a master running on a device behind a router. I am getting an error on the router with line icmp time exceeded when ESP32 is replying to the master. The packet routes just fine to the ESP32 and to the master but it gets dropped...

Re: tensorflow lite micro examples repo

We just try to realize a project with an esp32-s3 platform to classify sound events. We are using the https://github.com/espressif/tflite-micro-esp-examples repo which working fine and compiles on idf master also using ai acceleration of the esp32-s3 However we need a framework for setting up and l...

Re: Multiple Serial devices connection with ESP32-S2

I am using ESP32-S2 chip in my design. ESP32-S2 supports only two serial hardware channels. But I have three devices that needs serial communication. 1- USB to UART converter chip, 2- Coin dispenser device, 3- RPI serial communication. Can I use SPDT switch for selecting from two serial devices? Wi...

Re: How to get the gateway (router) MAC address when i using eth connection ?

To get the MAC address of the gateway (router) when using eth connection with Espressif ESP-IDF framework for the ESP32, you can use the following code: #include "esp_system.h" #include "esp_netif.h" #include "esp_eth.h" #include "esp_log.h" #include "esp_netif_dhcpc.h" esp_eth_handle_t eth_handle =...

Re: How do I program a version number into my firmware?

I want this to show up in the startup log, after the partition table info or thereabouts. I’m using PlatformIO and I don’t see how I can do this. Anyone know how? (I know how to put a version number in my own code and print it. That will show up much later that the startup log.) check the Custom bo...

Re: ESP32 ISA reference manual

Hi Rudi, It is possible to get the ISA reference manual (and the rest of the Xtensa SDK, in fact) from Cadence under NDA. A few of our customers did get access to the xt-xcc compiler from Cadence this way. You can contact Cadence directly (saying that you are developing a product based on the ESP32...
