BC95-G NIDD issue

Hello,

I’ve met the situation like described at: BC95-G issues with command CSODCP
But my network provider told that they support NONIP messaging.

From UEMonitor log I see:

nas_dbg_nas_msg.direction=DL_PDU
nas_dbg_nas_msg.msg_type=L3_EMM_ATTACH_ACCEPT

                    esmMessageContainer:

For any variant of “at+csodcp” I’m getting
+CME ERROR: 50

Can anybody help me understand what’s going on?

please Upload related debug logs and debug logs

Log attached.

The same sim-card.
The same area, but sim7080g device works well: could send nonip data successfully.

It is strange enough.

Please configure APN AT+CFUN=0 and try again, or the network does not support non-IP
NIDD testing.pdf (130.8 KB)

Network definitely supports non-IP messaging:

  1. Network provider told “support”
  2. I could send non-IP data via sim7080g device using the same sim-card and the same network provider.

AT+QCGDEFCONT=?
ERROR

AT+QCGDEFCONT?
ERROR

Looks like firmware has no such command :frowning:

I’m using BC95GJBR01A08 firmware.

AT+CFUN=0
AT+CGDCONT=0,“NONIP”,“apn”,
AT+CFUN=1
AT+CGATT=1

AT+CGDCONT=0,“NONIP”,“apn”,

return ERROR always.
I can set AT+CGDCONT=1,“NONIP”,“apn”, only

With AT+CFUN=0
AT+CGDCONT returns ERROR always moreover.

I can use AT+CGDCONT=1,“NONIP”,“apn
after AT+CFUN=1 only

Is it correct?

OK,please execute AT+CGDCONT=1,“NONIP”,“apn ” // apn Indicates the APN provided by the SIM card

Well.

ATTACH REJECT for today.

I have to wait for a while.

Let’s return to this question a couple of weeks.

Check whether the APN is consistent with the value provided by the SIM card
