try exporting short call file.
In the Long call file, messages will not be capture properly.
You can also select “New export plan” and select the required filter. Also try expanding “Layer 3 header” colomn.
The only columns I can export from Layer 3 are:
Cell ID,BCCH, BSIC, LAC, Mode, TimeSlot, ARFCN, MAIO, Hopping Flag, HSN, Link Type, Logical Channel, TI/SI, Primitive, IEI Message, Parameters, IEI, TDMA Frame Number.
IEI Message is empty. I exported a short call file, still nothing. What I’m doing wrong?
