I received the BC95-G and am trying to make it work.
However, i notice that the command AT+CFUN? returns 0
If i send AT+CFUN=1 the module responds after 2s with
+CME ERROR: 4 Operation Not supported
any suggestion as to where should i start looking for a solution?
The response to cmd AT+CPIN? is “+CME ERROR:524”
The SIM is supposedly for a network type “NB-IoT band 28”.
I do NOT know if the SIM is damaged or not as i don’t know how to test the actual SIM (but its a brand new SIM).
i did insert the SIM into a std smartphone & i could send an SMS…but i’m not sure if that proves anything.
The version on the BC95-G is Revision:BC95GJBR01A07…is that OK?
Have you ever upgraded the firmware?
Anyone gave you this version BC95GJBR01A07?
Please take photo of the BC95 , the FAEs can get the hardware version of your BC95G module, and then he can determine which version should be ok.
Please send email to support@quectel,com.
AT+CFUN always return 0 and cannot change it by AT+CFUN=1. Mostly because the owner upgraded it with a different base line firmware version.
Try to restore the cefs by AT+QPRTPARA=3, check whether it works .
If not, I think you should upgrade the firmware.
Take photo of the module , told the email@example.com that you need factory firmware version to reflash your module. And the current version is BC95GJBR01A07.
AT+QPRTPARA=3 is used for backup the parameters of RF related.
AT+CFUN=1 STILL RETURNS ERROR 4 — > Operation not supported。
The firstname.lastname@example.org didn’t gave you the firmware what you need. You have to tell them AT+CFUN always returned 0 and AT+CFUN=1 returned error.
