ESP32S3 Ethernet connection with IPV6 address

Hi, I'm trying to include a IPV6 feature for MODBUS TCP/IP stack which works flawlessly with IPV4 but once I assign IPV6 address and also change the TCP/IP mode to IPV6, there is no connection establishment. Can someone point me to example initialisation for ethernet IPV6, cause I can't find one exa...

Re: w5500 MAC triggering an unrecoverable error.

Hi, Chipset: ESP32S3 IDF version: v5.1.4 Custom PCB with U12-W5500 module and ethernet port placed less than 2 cm away from the chip. Ethernet initialisation is the basic initialisation example. I've been using the same ethernet port to host a local web server which works without any issue. Now I ha...

w5500 MAC triggering an unrecoverable error.

In my application, I have initialised Ethernet in a standard mode with clock speed of 30MHZ. I also use the SPIRAM. Both the application share the same bus config and hosted using SPI_HOST 2. I was previously hosting a web server along side using PSRAM, which never had any problem. However, now I ha...

ESP32 assert failed: block_next tlsf_block_functions.h:94 (!block_is_last(block))

This project Incorporates Ethernet SPI for hosting local web page and SD card for data logging in sdspi mode. Moreover, I have enabled SPIRAM and use it for other dynamic memory allocation. I have 4 RTOS tasks running in the background, 2 for UART operations while other task is the data logging (wri...

Re: sharing UART for multiple tasks.

Any Modbus request with the correct checksum that is received in UART port 2 constitutes a packet. At the moment, given that data logging task is initialised with lower priority, it misses a few logging cycles whenever UART1 is occupied. Moreover, the data logging contains time stamp, therefore usin...

sharing UART for multiple tasks.

Hi there, I'm developing a device for data logging purpose. It mostly performs 2 FreeRTOS tasks. Firstly, forward all the packets received at UART2 to UART1 and vice versa (High priority). Secondly, send requests of its own to gather data for logging register values via UART1 (lower priority). As yo...

Re: ESP32-dev-kitc MQTT SSL Muthual auth. cannot connect

Can you share the menuconfig options set for "TLS Key Exchange Methods"? Take a look at the ciphersuites that are enabled here.

Re: Using Miniz compression for JSON packet.

If anyone looking for decompression algorithm for their JSON packets, give a brotli compression a try: [url][/https://github.com/martinberlin/brotli/ ... e/compress]. Very simple and effective.
