How to send 7k bytes of data using USB in custom board.

[Madhu Mohan Reddy]

Hi,
I am using nRF52840 and nRF Connect SDK V2.6.0

I want to send 7000 bytes of data using USB at a time.
Now I am able to send only 1024 bytes at a time.
I modified USB CONSOLE sample and using uart_fifo_fill(); I am sending the data to PC

Thank you in advance.

Hi,

You can see from the documentation that the maximum size of an ISO IN transfer & isochronous OUT transfer in USB full-speed is 1023 bytes. So unfortunately you won't be able to send 7000bytes at a time using the USB interface. But maybe you can send them in chunks of bytes and send them one by one.
