Cannot send RTR #8

Closed ManuelWiddel closed 1 year ago

ManuelWiddel commented 1 year ago

Hey, so I could not figure out any way to set the RTR bit when sending a message, the struct can_frame doesn't have an option for that.

How difficult would it be to implement that? I'd love to use this library because everything that I need it for works, except for RTR, which is pretty important unfortunately.

Ok I figured it out, there is a flag within the "sendMessage" function, which is not accessable from outside the library. By changing this flag, I was able to send RTR messages correctly.
