Hi, I am trying to retrieve information relating to surrounding cell towers. I execute the AT+CCED=0,16,1 command and have noticed the following…
If I call it after the bearer is attached and I am connected to my server, then I do not get complete information for the neighbouring cells, i.e. RxLevels and TA fields are empty.
If I call the command from Dev Studio while the mode is in idle and does not have the bearer attached etc, then I get all the information I want (as below)…
So I thought I would call CCED before I attach my bearer. So I start up and wait for network registration. Once registered I sent the CCED command, but then I only get very minimal information relating to the neighbouring cells (as below).
2014/04/01;12:50:42:920;001;ADL;1;WEB: ModemDetails = +CCED: 234,10,3ee2,4eb0,55,104,,,,255,,,0,38,38,5,234,10,3ee2,,41,123,27,22,22,5,0,0,,,,,,,,,0,0,,,,,,,,,1,,,
So it seems that there must be a optimum time to call the command to get all the information? Is that true? I suspect it is after we have network registration and before attaching the bearer. But clearly not just after network registration?
Does anyone have any idea what I need to wait for, or when the best time to send the command is?
Thanks in advance.
