CAN Bus using mcp2515 not receiving extended id messages

SpenZerX commented 9 months ago

The problem

Hello,

esphome on 1st gen dual core ESP 32 (board: esp32dev)

component mcp2515 is not receiving any can messages with extended id.

Transmitted can messages with extended id are received by the destination, Transmitting seems to work.

Enabled mode: LOOPBACK for testing There is no echo on can messages sent with extended id!

Echo is OK on messages sent without extended ID -> SPI communication should be ok.

May be old issue #2642 is not fixed? Similar to issue #4885 https://community.home-assistant.io/t/problems-with-extended-id-esphome-mcp2515-can-bus/614512

Which version of ESPHome has the issue?

canbus:

interval:
  - interval: 10sec
    then:
    - canbus.send:

Anything in the logs that might be useful for us?

I'm having the same exact problem.

Same problem, MCP2515 does not receive the extended can_id but it can send them and I receive them well with a SN65HVD230 board.
