FMC003 requesting vehicle speed via ble from custom app

[SpeedlessDriving]

Hi I’m trying to determine the cur correct command. I need to send to the FMC003 to request it return polling vehicle speed back to my app via BLE

The vehicle speed needs to come from the vehicle not from GPS

I’ve been advised from reading docs the commands should be

@sms_run readio 37 ( for vehicle speed )

When I sent this command

The response is as shown in the upload ( not supported or not enabled io element requested )

The intent is to have the FC003 report in real time the vehicle speed off the CAN and not use GPS calculated vehicle speed

Any assistance would be appreciated

Hi Please make sure that the Vehicle speed from the OBD tab is enabled

[SpeedlessDriving]

These are the screen shore for the config tool and also the command I send to the tracker and its response

Please advise if the command syntax is correct and the IO is also correct for OBD vehicle speed as clearly the tracking suggests in its reply it does it recognise the command

Hi is the vehicle moving while you are sending the commands?

[SpeedlessDriving]

No I am testing with obd2 powered to 22 volt but not attached to vehicle

This however does not matter from my experience as when I send comment getvin it returns an NA value as the obd2 is not connected to the car which makes sense.

So if proves to me vehicle speed should return similar na value not an error message advising as shown in screen shots in this post

Can I please have someone confirm that command I am sending to request for vehicle speed from obd2 is in the correct format and correct is value

Hi

Please test once the vehicle starts to move or take only the parameters that are available like the GSM signal, ICCID, External voltage etc.

i am able to test the command @sum_run:readio24 *this being the GPS speed not the OBD@ speed) whilst the fmc003 is not connected to the car yet powered by 12v and it returns a 0 value which makes sense as the obd2 is stationary. Given this logic would not sending the 37 command to the obd2 return a similar 0 value rather than the error message. "NOT SUPPORTED OR NOT ENABLED

Vehicle speed should be available for the OBD parameters

To get OBD parameters please make sure it is connected to the OBD port of the vehicle
