Why connect antenna and set config band done, but AT+CSQ = 99,99
I set
AT+QCFG=“band”,0x00x,0x97 only
Do I need to set AT anything else?
I use BG951A on my own designed PCB.
Pls run
AT+QENG=“servingcell”

Thank you for reply.
This is result
First you need to make sure that the band you are locking is the right band or the local network band，Then you need to check that the terminal’s antenna connection is normal and good
Shouldn’t that command be:
AT+QCFG="band",0,97
This is for bands B1, B2, B3, B5 and B8…
