Hey folks. So ive got the photon talking SLCAN over to my linux PC using slcand and it SEEMS to work (I get data using candump/cansniffer). What im trying to do is to make sure its actually communicating over CAN so im trying to do something super simple like query the ODB2 for engine RPM. I seem to never get a response to this message. Im tried using cansend/cansniffer over SLCAN and thinking that maybe something is wrong with the SLCAN implementation also tried to have code run directly on the photon looking for ODB2 replies over an id of 0x700.
Im stumped since I get nothing.
What im trying to send with cansend is:
cansend can0 7df#02010c0000000000 - I do see 7df in cansniffer but no replies whatsoever (ID over 0x700)
I've also tried a custom application: https://github.com/frk2/carloop-obd-publisher/blob/master/application.cpp
Also no replies. I can see other can messages just fine. Im guessing im missing something basic here - what am I doing wrong?
