Hello @herbert.pan-Q I am using the BC660-GL development board. I have been trying to set the Band to 20 .
The AT command goes through successfully but when I query the band again it is still the same
[14:20:40.003]IN¡û¡ôAT+QBAND=1,20
OK
[14:20:50.538]OUT¡ú¡óAT+QBAND=?
¡õ
[14:20:50.538]IN¡û¡ôAT+QBAND=?
+QBAND: (0-17),(1,2,3,4,5,8,12,13,17,18,1
[14:20:50.569]IN¡û¡ô9,20,25,28,66,70,85)
OK
the chipset is BC660K-GL
I was able to sort it
Using AT+QBAND?
instead of AT+QBAND=?
I am having trouble with the reporting of our NB-IoT devices
They are sending reports intermittently. The chipset we are using is BC660K-GL
On monitoring the behaviour when the devices eventually send reports, it sends up to 10 reports at a go the goes silent again. What could be causing this?
Yes, if you are querying configuration parameters, please execute AT+QBAND?
What exactly does the report mean and can you provide the corresponding log?
