OpenMv H7 image transfer raw as the controller

I’m trying to transfer image data via rpc library. I’ve tried to use “” file then uncommented

interface = rpc.rpc_uart_master(baudrate=115200)

and wired to P4 and P5 pins to the microcontroller(STM32 Disco Kit) for UART communication.

But there is no any meaningful data. “{<\0><\0><\0><\0>_<9><9><18>{<\0><\0>”
Then I’ve tried “”, the result was the same. When I commented all the functions out then just have send “Hello World!\n”, the transfer was successful.

What is wrong with the image transfer raw functions or file?
Best Regards,

You have to run a the RPC library also on the device that’s talking to the camera. See the Arduino RPC library.
