At+cfun=1 error

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

Hi LeTLinh,

you can try to wait a while before sending the AT command,such as15s,determined by network.
