SDO Query (Temp) over CANOpen?

SDO Query (Temp) over CANOpen? was created by pugwng
Hi, I have a FBL2360 and a CAN Sniffer. I`m trying to query the Temp (0x201F) sending the message over the CANBus, but I dont receive the response from Roboteq. I can see the Heartbeat, so I guess the the CAN is working.
I tried to send the three following queries -- Data(HEX):

40 21 0F 01 00 00 00 00
40 0F 21 01 00 00 00 00
40 01 0F 21 00 00 00 00

Could you please give me some guidance or tip.

Attached are the pictures taken from the Sniffer app.

Thanks in advance

Hello,

First quering the Temperatures the index is 0x210F.

The CAN Frame including the Header should be as shown in the attachment, if NodeId is 1.
