Re: ESP_ping issue in v3.3-beta3
I Upgraded from 3.1, master is doing the same thing. Actually my previous thought was wrong, the issue had nothing to do with the interface call. The issue is ping process starting before wifi stack (I use ethernet interface as well). So what I did is put a flag so it waits for wifi to initialize an...

Re: ESP_ping issue in v3.3-beta3
I found the issue! I was calling the following function in my ping task every 100 ms, and apparently calling this too often will choke the wifi stack in the new version of IDF, can someone please clarify why?
ESP_ERROR_CHECK(tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_ETH, &ip));
ESP_ERROR_CHECK(tcpip_adapter_get_ip_info(TCPIP_ADAPTER_IF_ETH, &ip));

ESP_ping issue in v3.3-beta3
It seems like there is an issue with the esp_ping that causes wifi driver to stop acting properly. I had a code that has been running for a while, but as soon as I updated to this version of IDF it stopped working. The program is running a task called main which checks for connectivity by pinging th...

Re: PICO-D4 SMA Antenna Matching
Hi Guys, Thank you very much for the reply. I think I'm not perfectly describing the question. I do have plenty of stitching and pi network in place and I'm not getting rid of them. My actual question is not about whether or not have them, it's about the actual tuning process. How could one go after...

Re: PICO-D4 SMA Antenna Matching
If you want maximum RF performance then a matching network will always help you achieve this. One option is to contact sales and ask for advice from an RF engineer, as Sprite suggests. However, a good place to start first is the ESP32-PICO-KIT reference design which you can find on the espressif.co...

Hardware Interrupt For Flash Protection
Hi, In order to prevent flash corruption, I have been taking extra precautions to minimize flash writes. But when it's time for firmware upgrades (OTA), then there is nothing I can do. However I have a power management IC and a super cap which can let me know about a second before power completely d...

PICO-D4 SMA Antenna Matching
I'm designing a board with PICO-D4 and SMA connector. I'm also having the PCB fabricated with 50 ohm impedence control on the RF line and my RF line is only 7mm long. Do I need a pi matching network for this? I Would like to mention I'm using this device as a sniffer so I would like to get as accura...

Re: OTA transmission encryption flash.
I believe there are multiple functions for writing to the Flash. According to: https://demo-dijiudu.readthedocs.io/en/latest/security/flash-encryption.html It says: The ROM function esp_rom_spiflash_write_encrypted will write encrypted data to flash, the ROM function SPIWrite will write unencrypted ...
