using an external service to parse incoming messages from device in plugin

VamsiKrishnaYenumala

Hi,
I am facing an issue in parsing the variable data coming in 'CAN iQ' (cellocator) devices where I get the CAN data in 'variable Id' related to each parameter name and the data related to each parameter as 'variable data'.
now this 'variable Id' and 'variable data' differ from device to device as per the CAN data sent by the vehicle.
example:
for device A:
variable.id.1 = 32774 - belongs to parameter name 'fuel level'
variable.data.hex.1 = 00000000 - belongs to the data for 'fuel level' in % after decrypting the data.

and for device B:
variable.id.1 = 32775 - belongs to parameter name 'engine rpm'
variable.data.hex.1 = 00000000 - belongs to the data for 'engine rpm' in rpm after decrypting the data.

now I would like to use a single plugin where i use an external service created by me which can check what variable.id has what parameter after decrypting the decimal and send to it and as per new decrypted parameter name, that means.
for device A:
variable.id.1 = 32774 becomes 'fuel level'

and for device B:
variable.id.1 = 32775 becomes 'engine rpm'

can anybody help me with this, this is the solution i am looking for cellocator CAN iQ devices. @namo @baja

Hi VamsiKrishnaYenumala ,
I think you can use a plugin with PVM code without any external service to solve your task.
If I understand it correctly, you need a code like this:

if is_set .variable.id.1:
	.variable.id.1[number] ==> $variable_id
	switch[$variable_id]:
		32774:
			.variable.data.hex.1 ==> %hex ==> #fuel.level
		32775:
			.variable.data.hex.1 ==> %hex ==> #engine.rpm

It will work if your data conversion is not dependent on any data except presented in the message.
