However, when I moved to the new IDF, its taking about 2 sec; even though it shouldnt take more than 500 ms with the settings Im using. I recently acquired a pair of "Hanrun" LAN8720 boards in the hope to create a "transparent bridge" using it and one of my esp32 dev I noticed that on the old IDF, I was able to do an active WiFi scan in about 1 sec (time between call to esp_wifi_start_scan() to SYSTEM_EVENT_SCAN_DONE). 0. Hi I am having problem with slow connection with my ESP32. Connecting a third basically freezes everything. The aim of this prototype was to get a network latency between the ESP32 and the PC as low as possible (around 6-10ms would be great) with a consistent packet size of 512 bytes. Post by antds dev » Thu Nov 04, 2021 11:06 am . Interestingly, if I set up an Nginx proxy on my local machine, which creates a port for the ESP32 to connect to and forwards all The ESP32 is capable to activate the energy saving modes of light sleep and deep sleep, but in many cases we cannot use such a solution, but it is still possible to apply some options to the functional units for reducing energy consumption. The trick with the config function to bypass the DHCP doesn't work for me on the ESP32. As a point of reference I built the I'm working on a project with an ESP32-S3 that connects to my WiFi and transfers data to a cloud server via WebSocket. I’m currently working on prototyping WIFI connection between my ESP-WROVER-KIT and my PC. 4. On ESP32 I only use the BLE module. It stays disconected if i use The correct way to do this is WiFi. After that everything seems to work quick - DHCP acquires address in about 0. Even a blank sketch for ESP32 is taking 21 seconds. In addition, the connection to the web server is very slow and I have to turn off all devices that have wifi (Phones etc. But often it is like this. I have successfully downloaded small file few KB I have some code, that is working with WIFI flawlessly. I flashed it to my ESP-32S configured it - and it's work fine. But when wifi Using the HelloServer. For this reason, the sending task is a I just installed WLED on an ESP32 and after a couple minutes of poking around in the WebUI it got really slow and I noticed packet loss from my ping tests. A similar server (with ESP8266 default libraries) running on an ESP-12F has reasonable response times. Through the BLE I'm able to update STM32 firmware, by sending new firmware to an external flash. 3: 372: May 6, 2021 Esp32 Wifi problem. 1 seconds Espressif Systems is a fabless semiconductor company providing cutting-edge low power WiFi SoCs and wireless solutions for wireless communications and Internet of Things applications. 3 back onto the Feather and wrote a simple WiFi TCP server to just read and discard data sent from a Python client on my laptop. Has anyone had those problems before? what can I I'm working on an LED project using a esp32 with WLED running on it as the controller. The first few times I tried, I left it alone for 20 minutes and it still wasn't able to connect. Edit on edit: After turning on verbose logging, I realized that what ping actually does is to the effect of ping -c 5, with 1 second between pings. Is there any way this, and for that matter esp_wifi_start() can be sped up as a 19ms overhead is massive for my application? PS: I have played with reducing the cpu mhz during the esp_wifi_stop() and esp_wifi_stop() calls and it slows them down a lot. The ESP32 TRM describes two RTC boot methods in 31. 6 seconds with DHCP. 6 secs, measured in ESP32 code. ESP-NOW slow acknowledge from receiver . begin(ssid, password); and after second or two, when wifi connections is established (ESP32 is STA and connect to my home AP) Main loop lasts 1930 us, normaly it last about 1us. Super slow sdcard on Wrover kit. Very Slow build time. Have someone tested the esp-32s? Maybe - i used the wrong Packet sniffing too slow? 1 post • Page 1 of 1. This uses RTC slow memory, and the TRM suggests that it might be a bit quicker: The same slow / unreliable connect was also there when using the Arduino support. Let's set the sleep mode, disable the WiFi and scale the f In addition, the connection to the web server is very slow and I have to turn off all devices that have wifi (Phones etc. I say "seem to" because debugging this is rather elusive; in order to enter sleep mode, I disconnect my serial cable which of course Espressif Systems is a fabless semiconductor company providing cutting-edge low power WiFi SoCs and wireless solutions for wireless communications and Internet of Things applications. TCP server is slow. Then I 9ms seems like a long time to turn off the WiFi. Which include but are not limited to the following: FreeRtos slow?

Now with ESP32, all attempts return 2. urbanze Posts: 301 Joined: Sat Jun 10, 2017 9:55 pm Location: Brazil. I have set the wifi_scan_config_t as follows: Espressif ESP32 Official Forum Skip to content. v3. I would show video, but it's so boring! Anyway, checking the Task manager shows 0% task usage for the Bash shell, which means it would probably build a lot faster on an ESP32 device, let alone a 3. bgn Espressif Systems is a fabless semiconductor company providing cutting-edge low power WiFi SoCs and wireless solutions for wireless communications and Internet of Things applications. Then on the third try it connects again and so on. The unanswered (I have seen multiple posts on this but no answer) question leads some to think the part is buggy or otherwise impractical for their project and they move on. I started by using the following configuration to let the driver reset the RTS pin automatically after the UART Tx is completed: Code: Select all. qlveufy efwzi zpwy figrg pjdzh ieipayx awgz uzxil jualr zvfgg
