If you’re using M2M studio you can see them in the “Traces View” when running the application. It’s in the Target Management perspective, M2M studio automatically switches to it after downloading an application to the module.
You probably have to first configurate the trace levels that you want to see (in the button “Remote traces configuration”, beware that it’s kind of buggy and sometimes it won’t let you select the trace levels… ) or nothing will appear.
-> Connect to Hardware (Target Manager) usualy Com 1, 115200 Baut, 8 data, none parity, 1 stop
-> Select the Project (not any file, the project itself)
-> klick to arrow-down (the black one) near the run button (green arrow)
-> Run Configuration -> click “new”
Now, there should be a new configuration called same as your project
try connecting with hypertrm and sending “at+wopen=0” until you see reaction from the module
then try to set the traces.
also check if your module-ground is soldered to your dev-kit
