ESP32 Forum

I have been using the ESP-WROOM-32 modules for a few years without any problems.
I ordered more of these from AliExpress and I have found that the CAN controller no longer works.
My carrier board has the CTX and CRX assigned to IO15 and IO2.
I am using a VP230 transceiver.
Does the ESP32 still include the SJA1000 CAN bus controller.
I have tried three different suppliers and none appear to have a working CAN controller.

If this is a problem with the newer chips does anyone know where I can buy some with a working CAN controller.

Has anyone else had this problem.

Your code is based on Arduino or ESP-IDF?

Some new version of the IDE may have changed the code for the CAN protocol.
Compile your program with the old version of the IDE.
