Hej there! I ´ve a question about obd.query or obd.send
My car is a VW ID3. And its very tricky to handle.

I have a code to query the EV battery information. This is:
“03221e3b55555555” I have this information from this App EVNoify
At openvehicle i can find the same code at the vw eUP
#define VWUP_BAT_MGMT_U 0x1E3B
and at this wiki list

22 1E 3B (aa*2^8+bb)/4 V Spannung der Hochvolt-Batterie / Battery Voltage

In my test I always get this error “18DAF10A037FAAAAAA”
i ve test this:
obd.send 7E5#03221E3B expect_response=true auto_format=true
obd.send 03221E3B expect_response=true auto_format=true
obd.send 03221E3B55555555 expect_response=true auto_format=true
obd.send 03221E3B55555555 expect_response=true auto_format=true can_flow_control_id_pair=“7E5/7ED”

Or is it possible the change this to a “normal” query command?I have read a “query” is better than a “send”
Did you have any idea? What am I doing wrong?
