Hi there

I want to send RTR frame from microcontroller1 to microcontroller2. I don't know how I should Config the microconroller1. these are my HALCOGEN configuration:

and I am using

thanks Miro for your attention

I had read it before asking this question. Mr QJ Wang have said:

1. Does your receive object have the same ID? If the ID is different and the UMASK=1, the coming message will be filtered out.
2. The remote frame doesn't data, how do you know if it is received or not?
3. The receive object which want to receive the remote frame and transmit the data frame should be: Dir = 1 (direction = transmit), RmtEn = 1, UMask = 1 or 0.

1- all of message boxes have unique ID

2- I am watching the bus with "CAN Monitor" software.

3- I am sending RTR frame with message box 1 which is configured as transmitter and its "Enable RTR" checkbox is checked.

finally I found the solution.
direction must be RX and DLC must be equal to zero.
