Hello Sir,

Recently we got our Smart Gas Meter tested in CTT 4.3 release 103. The meter failed in HDLC_INFO_N3 test, and the report states "Response not RR". The Log is as follow.

Hi Girija, This is not Wrong…

Hi Girija,

This is not Wrong N(S) sequence number test. The command is wrong, but you ask more data. You need to check that.
