Another Spoofing Question

Hello again, Micheal's previous answer to my question about spoofing really helped clarify things. I am trying to apply that information now, and still not getting results from my car. So below is what I am trying starting from a fresh boot on the OVMS module, hoping to get my speedometer to move (in this case rise to 90mph). Any input, ideas or observations on what I am missing or doing wrong here?

OVMS# can can1 start listen 500000

(I tried all of these one at a time)
OVMS# can log start tcpserver transmit crtd
OVMS# can log start tcpserver transmit gvret-a
OVMS# can log start tcpserver transmit gvret-b
OVMS# can log start tcpserver transmit lawricel
OVMS# can log start tcpserver transmit pcap
OVMS# can log start tcpserver transmit raw

(Attempting to get my speedometer to go to 90 on Frame Id# 610 and it's btye #3 (5A))
OVMS# can can1 tx standard 610 20 00 5A 0C C0 FF FE E0

(Also tried variations of this)
OVMS# can can1 tx standard 610 5A

(And this)
OVMS# can can1 tx standard 0x610 0x5A

Another Spoofing Question

If you start the CAN bus in "listen" mode, you cannot transmit on it. You need to start it in "active" mode.

Be aware a speedometer may not respond to a single frame, you may need to adhere to some protocol or do periodic repetitions.

Regards,
Michael
