I am running +KCELL=1 in a loop and wrote a parsing engine for it. GSM parsinglooks OK, but UMTS has frequent failures based on values outside of what is specified in the AT Guide (version 19) for the HL8548.
UMTS is occasionally failing on LAC (value > 0xFFFF, it reports fffffd9d) or the scrambling code (value < 512 and seeing ffff). Maybe GSM had more tests that provided the “not available” for 255 values and UMTS did not have the same characterization?
On some occasions multiple UMTS serving cells are reporting in a single +KCELL=1. I have not seen this with GSM. Is this because UMTS allows multi-connect?
