HL7692 PDP Authentification failure

IoT Modules

Hello,
I use an APN with authentication is mandatory for a connection 4G.
I make the following orders:

AT+CGATT=0 ==> OK
AT+CGDCONT=2,“IP”,“MyAPN” ==> OK
AT+WPPP=2,2,“logIn”,'psw" ==> OK but i think it’s useless
AT+CGATT=1 ==> OK
AT+CGACT=1,2 ==> +CME ERROR: 149 (PDP Authentification failure)
AT+CREG? ==> +CREG: 0,5 OK
AT+CSQ ==> +CSQ: 16,99 OK
AT+COPS? ==> +COPS: 0,0,“F SFR”,0 OK

In your forum, i found:
*For HL7692, if the uname and pword are mandatory for the APN “o#####b.##”", you should not use AT+WPPP=1,1,"##UNAME##","##PWORD##", because +WPPP does not work for the external PPP dial up app (ATD 99 *1#).
Please input the uname and pword in the external PPP dial up app.

I prepared pppd (Linux) with authentication, but:
ATD99**2# ==> NO CARRIER

if i use an APN without authentication, it works fine.

Version: RHL769x.2.27.183100.201809071813.x7120m_3|

Thank you for your help

Hi JFTWIT

Please make sure your SIM supports CHAP authentication from your mobile service provider.
This issue has not been reproduced with the Amarisoft network simulator FW RHL769x.2.27 HL7692 at my side.
