The example is clearly the right way to go. Really appreciate the help form both of you!

I haven't tried it, but I think you just need to specify the IP address of the interface you want to bind to. SOCKET s = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); sockaddr_in localaddr = {0}; localaddr.sin_family = AF_INET; // for WiFi localaddr.sin_addr.s_addr = inet_addr("192.168.10.103"); // fo...

Greetings, I am using both ethernet and wifi in the current project. Does setting the default net_if to one of the two before each time socket connect is called force the socket to be bound with the specific net_if? Assume the target ip address is in an ip section of neither net_ifs and and ip_v4 ro...

Yes, I think so. Maybe there is some other reasons causing my problem. I will check it again.

Dear aliarifat794

Thanks a lot for the help. Both checking UART_TX_DONE status bit and adding a delay before sending the next byte are promising solutions. For checking the status bit, could you give some hints on how to get it, since I can't find any info in the idf document.

Best regards

Greetings,

Is there any methods to check the data that is written into uart tx fifo has been sent out by the hardware after calling uart_hal_tx_fifo_write(). It seems UART_TX_DONE interrupt just indicates tx fifo is empty instead of assuring the data has been actually sent out.

Regards

Greetings, SoC platform:esp32-U4WDH idf version:v4.4 After reading the esp32 SoC errata, I come up with a question regarding the problem stated in section 3.21. It says when cpu reading five specific FIFO register addresses, if interrupts occur, the reading process will be interrupted and subsequent...

Dear MicroController, Thanks a lot for the reply, thought the topic has sunk. Using a14 to store gpio address for further toggling is indeed what should've been done and I will make the correction. Besides this, since I am not familiar with using assembly language and the code's frame was adopted fr...

Hi, chip: esp32-U4WDH IDF version:v4.4 with commit 8153bfe412 platform: vscode on linux description: Need low latency gpio interrupt, so wrote the following code in assembly to test the feasibility. ETS_GPIO_INTR_SOURCE is linked to number 31 of the interrupt matrix using intr_matrix_set(). The trig...
