crash on uart_read_bytes after some time

I have seen this crash a few times on esp_idf_v3.3 what could cause the crash when calling the uart_read_bytes function?? We only read one byte at a time to get NMEA messages // Read data from the UART int len = uart_read_bytes(gps_uart_port, (uint8_t*) data, 1, pdMS_TO_TICKS(2000)); Guru Meditation...

Maximum number of open files

What is the maximum number of open files that we can have at the same time with esp-idf, and what are the configurations to get to this value?

currently we can't open more than 5. Is there a way to increase this number?

Re: CoAP between two ESP 32

Got it to work with 2 esp32. But not with coap://californium.eclipse.org
The message handler is called, but COAP_RESPONSE_CLASS(received->hdr->code) returns 4 instead of 2.

Does someone know what coap response class means and if that's what I should be getting from this URI?

Re: CoAP between two ESP 32

I tested the CoAP server example and it worked fine using a java program to send the GET commands. Next thing I did was trying to get an esp32 with the client example to connect to the esp32 with the server example. The server shows that a GET command was indeed received, but either the response mes...
