I was Unable to use RTR(Remote Transmission Request) in CAN using STM32F407VGT6 and STM32F302R8

I tried to send a RTR frame to another CAN peripheral , another node received the RTR bit successfully and RTR bit in the node has been set.

Does the node receiving the RTR frame will transmit the Message automatically? or We have to read the RTR bit and send the Message Manually?

Other than RTR bit Do I need to set any other Bits in other registers ?

Hello,

Indeed, you need to detect the RTR bit and reply manually.
