I did a configuration on sd_card example: int iOk,iCount; FIL iHandle; f_unlink((const TCHAR*)"/demodir/r.txt"); iOk=f_open(&iHandle,(TCHAR*)"/demodir/r.txt",(BYTE)(FA_CREATE_NEW|FA_WRITE)); gpio_pad_select_gpio(25); gpio_set_direction(25, GPIO_MODE_INPUT); gpio_set_pull_mode(25, GPIO_PULLUP_ONLY); ...

Dear,

I use tcp_perf test from idf( example/performance) without modification and send continuously data to another laptop(access into the AP wifi created by esp32) and receive by Hercules(terminal)

my board is ESP-wrover-kit(black)

quanvu,

if code size is big, make a modification on partition

kbaud1, deeply appreciate for your rep. As you mentioned, we cared the specs of MCU from document only and picked it. Unfortunately, there were a few reviews about performance at that time. Now, besides throughput, we also face the other problems such as the stability when running bluetooth and wifi...

Besides idf/examples/performance/tcp_perf ( which gives around 1.8Mbit/sec, I used also idfexamples/wifi/iperf) and did as the manual "readme". weirdly, I got ~ 8Mbit/sec!!!. The result is highly different from the "examples/performance/tcp_perf" could any one give e an explanation and how can I mak...

there has been already a question about tcp throughput here: https://esp32.com/viewtopic.php?t=126 however, no one gives a method (either software or hardware) to improve the speed. While someone can get 10Mbyte/sec, My ESP32 wrover-kit still gives around 200KByte/sec!!!! I test using iperl from new...

Hi there, I also am facing a similar. my esp32 (configured as AP) shows there is a new station connected into it ( even though the station has been connected and transfered data already): I (4001604) wifi: n:1 1, o:1 1, ap:1 1, sta:255 255, prof:1 I (4001604) wifi: station: 74:e5:43:04:86:99 join, A...

I use the tcpiperl to test speed and operation of tcp transmission, some time and especially highly frequently occurs when ble is enabled at the same time is, wifi automatically drops, tcp cannot send (sent byte is -1) and return error 104 connection reset by peer. At that time, my pc couln't ping e...

I just finished a streaming video (stored in sd card of esp) via wifi tcp ( by samba protocol), however for a big video (high resolution and big fps), esp almost drops down after a moment, especially when enabling bluetooth. I suspect that some parameters of wifi weren't configured well to support f...

So, eventually, I2C cant work simultaneously with WLan, it seems that is a bug of SDK or hardware, should we report to company to fix or what else should we do?
