Hi,

> Hello, I’m trying to research relevant steps to get into a module test mode for EM7455 for LTE module integration (propably similar to other modules of that series), because of a CE certification procedure. In discussion with our measurement laboratory service partner they require that the module needs to enter a continuous transmission testing mode to reach EMC requirements. The AT commands documentation describes a test mode section with options like: enter a factory test mode (AT!DAFTMACT…

Thank you so much!!! This did solved my problem.  
For anyone who might be interested. There is a very important at command that is not mentioned anywhere in the at command list reference nor the technical specification of MC7430, which is a huge negligence for such a big company(AT!DALSTXPWR=1,23 #turn transiver on with 23dbm output). I found this command in the technical specification of EM7455.
