How to send data over CAN-Bus using ESP32 Module using MicroPython?

Question

I have an ESP32 module connected to my computer. I am using Thonny IDE to program my ESP32 device using micropython code. I am trying to send data over CAN bus but I m getting error.

code:

from machine import CAN

can = CAN(mode=CAN.NORMAL, baudrate=500000, pins=('P22', 'P23'))
can.send(id=12, data=bytes([1, 2, 3, 4, 5, 6, 7, 8]))
can.recv()

error:

ImportError: can't import name CAN

And even if it were allowed: a screenshot is clearly a far less suited way to read code than the code itself. — gspr, Jan 06 '22 at 13:26
[The ESP32 build of MicroPython doesn't seem to support the CAN API.](https://github.com/micropython/micropython/issues/5087) — gre_gor, Jan 06 '22 at 13:31

At the time of writing this answer, according to this GitHub issue, the CAN API doesn't seem to be supported on the ESP32 build of MicroPython.

There is a pull request for an implementation, but is currently not working.
