Re: ESP32 PICO D4 & External Ram

No body?
I'm specifically talking about the ESP-PSRAM64H.

Re: ESP32 PICO D4 & External Ram

Hello,
So Based on the PSRAM documentations, there is a 1.8V and 3.3V version available. Is this out yet? Does this mean now we can use PICO-D4 with external ram?

FPGA+ESP32 Intercommunication

Hello, I have been working on a project which requires fast data compression and sniffer mac OUI lookup on the device it self. Since the number of OUIS are way too large and we don't have hardware compression capabilities on the ESP32, I was thinking of using a small Lattice FPGA to do these two tas...

ESP32 TLS Over Lan8720

Hello,
I'm just wondering if we have TLS support for ethernet on ESP32 or not? All the examples I have been able to find are for WiFi.

ESP32 Sniffer Burst Sequence

Hello everybody, I have been using ESP32 for a research project for a while now. I mostly use the Sniffer API and I'm only using it to sniff management packets. I need to capture as many MGMT packets as possible. Based on my recent findings, if there is a burst of probes from a device (lets say a to...

ISSUE with xEventGroupWaitBits

Hi Guys, I'm having a heck of a problem with the "xEventGroupWaitBits(wifi_event_group, CONNECTED_BIT, false, true, portMAX_DELAY);" everything works fine if I call this function in the main loop, but if I call it from another RTOS task it crashes every time: /esp-idf/components/freertos/./event_gro...

Re: how to check if internet is available

Thanks Kolban for highlight "IP_LOST_TIMER_INTERVAL" parameter. I will check it. When I state "internet is available" I means that ESP32 is connected to a local access point which is connected to external internet. As you wrote I'm looking for a way to discover if the modem cable has been disconnec...

Re: Sync with NTP and trigger an interrupt every second the clock ticks

Dear ESP32 Guys and Girls, How would you accomplish the above mentioned Task? (Using ESP-IDF) I'm thinking of something similar: 1 Sync Time with NTP Service from a server and set the local clock in the ESP32 (this is well documented and working) 2 Read current usecond till next sec, register a Tim...
