Hi,
I use Quectel BC95 and control it through Arduino Uno. Previously I sent the command AT+CFUN=0 to the modem and reboot it. But after that I allways receive ERROR after the commanf AT+CFUN=1. I tried many sim Cards but none of them works. I allways receive ERROR back.
at+nconfig=autoconnect,false
OK
AT+NRB
REBOOTING
…
REBOOT_CAUSE_APPLICATION_AT
Neul
OK
AT+CFUN?
+CFUN:0
OK
AT+CFUN=1
ERROR
When I try the simcard with other modem the command AT+CFUN=1 still works there and I got the response OK.
Could you plese tell me what ist the Problem with this Quectel BC95 module?
Regards,
Linh
