MSP430i2040 Sub Metering EVM not reporting energy consumption data

I am evaluating the MSP430I2040 EVM for  a wireless single phase metering product.

I  was able to program the MSP430I2040 using IAR (with help from Mars). 

I  am able to get proper response to "GET_READINGS_PHASE_1"  command.  I get the expected  voltage and power values.

   I am now trying to get energy consumption data  by  sending "GET_CONSUMPTION_PHASE_1" to the EVM. I had to fix the max  allowed response  message size  from 34 to 66 to get a  response to "GET_CONSUMPTION_PHASE_1" cmd. I  am getting a  response but all  the energy values are zero. Can you tell me how to get the energy  values ?  Looks like energy calculation is  not supported  in the metrology library.

Thanks
