EHS6T - Authentication AT^SGAUTH - SM deactivation | Telit Cinterion IoT Developer Community

February 6, 2017 - 4:00pm, 5989 views


I'm trying to establish a connection to a customer private network with the EHS6T terminal. 

The customer has a SIM card with static IP address assigned by the ISP. I setup de authentication parameters with the command AT^SGAUTH, setup the APN with AT+CGCONT and connect with ATD*99***1#.

The terminal respond CONNECT and then the pppd ****** start the negociation. See the log :

Serial connection established.
using channel 251
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS3
rcvd [LCP ConfReq id=0x1 <asyncmap 0x0> <auth pap> <magic 0x225ffd20> <pcomp> <accomp>]

rcvd [LCP TermReq id=0x3]
LCP terminated by peer
sent [LCP TermAck id=0x3]

When I look at the error given by the terminal after the unsuccesful attemp I get this message:

+CEER: "SM deactivation",129,"User authentication failed"

I'm sure that the APN, login, password are correct. They have been tested with an other equipement.

Can u help me to solve this problem? It's really urgent!

thanks in advance
