TCPIP meter - flexradio/smartsdr-api-docs GitHub Wiki

Creates a meter within the radio that will accept values through the VITA49 port 4991 through UDP. All fields in the command are required.

 C[D]<seq_number>|meter create name=<name> type=<meter_type> min=<float_value> max=<float_value> units=<unit>

<name> = Name for the meter (must be 20 characters or less)
<meter_type> = the type of client that is requesting the meter (see table)
<min> = Minimum value for meter (floating point)
<max> = Max value for meter (floating point)
<unit> = This determines the scaling that the radio will use. DB|DBM|DBFS|VOLTS|AMPS|TEMPF|TEMPC|RPM|SWR

Example:

 C43|meter create name=MyAMP type=AMP min=0.0 max=1500.0 units=WATTS

The table below shows the currently supported <meter_type> parameters to the create command:

Responses

Response Example:

R43|27,0x88000000

Once a meter has been created the radio will accept meter packets on the standard VITA49 Port 4991.

Using the Metering protocol#Meter_Extension_Packet format you can create UDP VITA49 packets to provide streaming meter values for the meters you have created.

Several things must be set properly in the packet:

• The Stream Identifier field must be the <stream_id> given in the response to the "meter create" command.
• The Meter Identifier field must be the <meter_number> give in the response to the "meter create" command.

If you have created multiple meters you can bundle all the values in a singe VITA49 packet.

Since the VITA49 Meter packet only allows int16 scaling is done on certain units to get the reported value.
