I reset about 500 ESP32E and ESP32D at the same time. About 480 ESP32s were connected to the server normally, but about 10 to 20 ESP32s were unable to connect to the server for about 20 minutes. The ESP32s in question even succeeded in downloading data over an http connection, and then failed to con...

Yes, I'm using the WROOM32D module. Power directly applies 5v. Well, there's your problem. While our devboards have an on-board LDO and can accept 5V on the designated input pin, the modules only work on a voltage range around 3.3V, and you run the risk of damaging it if you run it at 5V. Chances a...

Are you using a WROOM32D module? Just checking: do you have a LDO or something that generates 3.3V in the power supply path, or are you feeding 5V directly into that module? Yes, I'm using the WROOM32D module. Power directly applies 5v. Only status LEDs are connected to the power line and there are...

You didn't state what ESP32 module you were using. 5v @ 700ma is pretty high. How hot is your 3.3v onboard regulator getting, can you keep your finger on it ? I'm using esp32 WROOM 32D. The chip temperature was not high. It didn't matter if I touched it with my hands. Is there any possibility that ...

Hello In my project, esp32 is operated by freertos. At core 0, wifi, Bluetooth, and ble mesh are working, but sometimes mesh dies. One of the logs that appear at this time is "scan_evt timeout". Can I know what happened? Power sources are supplied at 5v, 700ma at smps. And is the smps in use running...

Maybe it's for ESPFS? See the read-only filesystem https://github.com/jkent/libespfs
It used to be part of the libesphttpd project and has been split off into it's own module.

Thank you for the information. Looking at the code, I think your comment is correct.

ESPHTTPD can be given to subtypes during partitioning of esp32. When to use this option?

ESP_ERR_NO_MEM strongly indicates that you're using too much memory, and either mounting a filesystem or starting a https connection cannot be done anymore as there's no memory left. Thank you.. I found the problem.. I should have been suspicious when the memory error came out.. Memory management i...

Those two have very little to do with eachother. What error do you get specifically? When the code is executed in the order of 1. http client open 2. fat spiflash mount the log is I (3674) MAIN: Charger Firmware Download To HTTPS I (4900) MAIN: HTTPS OPEN. I (4900) MAIN: Mounting FAT filesystem E (...

Hi everyone. I want to save the file I receive from http in real time in flash memory as wear-leveling. However, when connecting with esp_vfs_fat_spiflash_mount and esp_http_client_open, only the one executed first works. I think this problem is caused by using the same line. Is there any way to sol...
