hi support team,
customer had one problem about "AT%XCBAND=? "
first. Customer try to set catm and catnb systemmode together as below, i could not see the band17 in list:
[16:43:53.099] AT%XFACTORYRESET=0
[16:48:21.233]
[16:48:21.233] OK
[16:48:21.233] AT%XFACTORYRESET=1
[16:48:23.659]
[16:48:23.659] OK
[16:48:23.659] AT%XBANDLOCK=1,"10001100000001010"
[16:48:26.335]
[16:48:26.335] OK
[16:48:26.335] AT%XBANDLOCK=2,"10001100000001010"
[16:48:29.173]
[16:48:29.173] OK
[16:48:29.173] AT%XCBAND=?
[16:48:32.368]
[16:48:32.368] %XCBAND: (2,4,12,13)
then we change systemmode to catnb only, it shows band17 as below:
[16:49:16.633] AT%XSYSTEMMODE=0,1,0,0
[16:49:21.557]
[16:49:21.557] OK
[16:49:21.557] AT%XCBAND=?
[16:49:26.089]
[16:49:26.089] %XCBAND: (2,4,12,13,17)
then. i start the modem as AT+CFUN=1, the band 17 show quite slow:
[16:49:56.018] AT+CFUN=1
[16:50:02.586]
[16:50:02.586] OK
[16:50:02.586] AT%XCBAND=?
[16:50:08.516]
[16:50:08.516] %XCBAND: (2,4,12,13)
[16:50:08.516]
[16:50:08.516] OK
[16:50:08.516] AT%XCBAND=?
[16:50:13.511]
[16:50:13.511] %XCBAND: (2,4,12,13)
[16:50:13.511]
[16:50:13.512] OK
[16:50:13.512] AT%XCBAND=?
[16:50:18.510]
[16:50:18.510] %XCBAND: (2,4,12,13)
[16:50:18.512]
[16:50:18.512] OK
[16:50:18.512] AT%XCBAND=?
[16:50:23.519]
[16:50:23.519] %XCBAND: (2,4,12,13,17)
[16:50:23.519]
[16:50:23.519] OK
the question is ,is there any reason for this command?
Regards,
William.
