Hello,

here is my code.

I want to control a charger via CanBus. I use an ESP32 with MCP2515 and the MCP library. This is connected to CanHack. Communication with the charger works. If I integrate ESP32 and MCP2515 into the ESPHOME bus system, everything works except for receiving extended IDs. Sending works!! StandardID works.

`captive_portal:

spi: id: McpSpi clk_pin: GPIO18 mosi_pin: GPIO23 miso_pin: GPIO19

switch:

platform: template name : "CanBus" id: "Switch_CanBus" turn_on_action: then:
- canbus.send: data: [0X20, 0x00] canbus_id: my_mcp2515 use_extended_id: true can_id: 0x000C0103
  
  remote_transmission_request: True
- delay: seconds: 2
turn_off_action: then:
- canbus.send: data: [0X30, 0x00] canbus_id: my_mcp2515 use_extended_id: true can_id: 0x000C0103
  remote_transmission_request: True
- delay: seconds: 2

canbus:

on_frame:
- can_id: 0x000C0003
  
  can_id_mask: 0x1fffffff
  
  use_extended_id: true then:
  - logger.log: "test"
  - lambda: |- std::string b(x.begin(), x.end()); ESP_LOGD("can extended id 0x123", "%s", &b[0] );
- can_id: 0x321
  
  can_id_mask: 0x1fffffff
  
  use_extended_id: False then:
  - logger.log: "test"
  - lambda: |- std::string b(x.begin(), x.end()); ESP_LOGD("can id 0x321", "%s", &b[0] ); `

LOOPBACK mode gives no echo on tx with extended id ... Please fix.
