Issue recording at 2kHz on SD card (Cyton v3.0.0, Python)

[NeuralControl]

Hello,
I am trying ask via python to record on sd card at 1kHz, using v3.0.0
I looked around and tried quite a bit but cant get it to work.
My code looks like below, does anyone knows what i'm doing wrong by chance?
i get createfdContiguous fail without softreset, and if i do a soft reset i get back to 250Hz,
Thanks

board.ser.write(b'~6');sleep(1);read() # ask 250Hz
board.ser.write(b'v');sleep(1);read() # soft reset
board.getSampleRate() # check 250.0
board.ser_write(b'a');sleep(1);read() # record ~14sec
sleep(20)
board.ser.write(b'~4');sleep(1);read() # ask 1kHz
board.ser.write(b'v');sleep(1);read() # soft reset
board.getSampleRate() # check 1kHz
board.ser_write(b'a');sleep(1);read() # record ~14sec
sleep(20)

Can you rephrase?

I think you are writing too fast too it
