I would like to know how to use esp32 as high bandwidth transmitter. Did you ever use this idea or why this have not updated?

I have hard time understanding your code so is there any example of usage or can you give small hints what i'm looking for?

ESP32 has an SDIO slave which is quite fast , And The Pi also has an SDIO Master in its 40Pin Header.
Could we add a new experimental branch which use SDIO? I think it could solve the speed bottleneck problems.
To achieve this , we need to write an simple linux driver to just gule the CMD and block w/r to standard linux ioctl and read/write.
It seems that linux doesn‘t support userspace sdio opration.(If i am wrong ,plz tell me below.)

I also notice that there is ESP-Hosted project .Howerver they are not fully opensourced (esp side closesource) ,don't support our featuers and not for high rate.
There are some refs:
esp-hosted
esp-idf SDIO Example
sdio_linux_fpga
nysa-sdio-linux-driver

Do you like it , jeanlemotan ? Or any others like it ? Let's build this weekend project together?!

Hi Jean!

I am sending a lot data to the esp32 with a PC, and just started to get this assertion.

assertion "m_count > 0" failed: file "include/wlan_queues.h", line 191, function: void Queue<N>::end_reading() [with unsigned int N = 40000u]

maybe i'm running out of memory? I increased the incoming buffer size to 40000.

Cheers
