Hi,

Can you read the meter without ciphering? Now data is encrypted and I can't check the content of it.

Hi,

You are sending two normal get responses and this is not correct. In GBT you add all data to one get response and then split that get response to GBT blocks.

Hi,Mikko
thanks for your reply,but I'm still having trouble now,I modified like you said,and I put the response data to the translator,it shows fine,I check Green book,there is a Additional_service_Parameter when use GBT in which the invocation_Type(COMPLETE,FIRST-PART,ONE-PART ,LAST-PART) parameter is mandatory, is it the possible reason?but I didn't find any example ,could you send me some examples about GBT and explain, appreciate ！below is the data :
