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...

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...

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...

Have you checked this?

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

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.

I realised that, hence moved everything to PSRAM as below:
unsigned char *window = (unsigned char *)heap_caps_malloc(WINDOW_SIZE, MALLOC_CAP_SPIRAM);
unsigned char *output = (unsigned char *)heap_caps_malloc(BUFFER_SIZE, MALLOC_CAP_SPIRAM);

Documentation for TAMP compression technique: [url][/https://tamp.readthedocs.io/en/latest/c_library.html]

Update on TAMP compression, the compression works fine. However, the decompression bytes are way out of line. For example: Compression successful! Original size: 9890 bytes Compressed size: 2005 bytes will return the decompression of: Decompression successful! Decompressed data: Decompressed size: 1...
