Em7455 will not syncornize

[e.gradine]

Unit is on Verizon network
Tried registering the the device with the IMEI and Serial number printed on the module and the IMEI and IMEI as the Serial number (which is what the modem returns from AT+CGSN). Same results from both.

AT+WDSS?
+WDSS: 0,“VZWINTERNET”
+WDSS: 1,0
OK

AT+WDSC?
+WDSC: 0,0
+WDSC: 1,1
+WDSC: 2,1
+WDSC: 3,1
+WDSC: 4,1,60,240,960,0,0,0,0
+WDSC: 5,1

AT+WDSS=1,1
OK
+WDSI=4
+WDSI=5
+WDSI=7

Any help would be appreciated

Are these WDSI indication? (not quite sure why it is = equal sign in the middle )

+WDSI=4
+WDSI=5
+WDSI=7

What do you set for AT+WDSI?
What is the return of AT+WDSG?

Did you check at+cgdcont? For the profile id when connect to the airvantage server?

Hi jyi,

For WDSI, those should be : not =
+WDSI: 4
+WDSI: 5
+WDSI: 7

AT+WSDI?
+WDSI: 8191
OK

AT+WDSG
+WDSG: 0,2
+WDSG: 1,0
OK

AT+CGDCONT?
+CGDCONT: 1,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 2,“IPV4V6”,“vzwadmin”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0
+CGDCONT: 3,“IPV4V6”,“VZINTERNET”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0

are you using the latest FW?

How many devices are seeing this issue?

Failed to connect RC76xx and AirVantage service

Hi @Vianney SIM is ok, I checked, I can oped PPP connection and send data, so the data channel is ok and the APN is correct. Today the device successfully connected with AVMS automatically after boot, but when I close session (AT+WDSS=1,0) and try to open it again, it wasn’t open, with no notification or errors +CREG: 1 +WDSI: 4 +WDSI: 6 +WDSI: 23,0 +WDSI: 4 +WDSI: 6 +WDSI: 23,1 at+wdss=1,0 OK +WDSI: 8 at+wdss=1,1 OK at+wdsg +WDSG: 0,3 +WDSG: 1,0 OK at+wdsi? +WDSI: 4479 at+…

you need to make sure no host platform is using the data connection

Verified the module is running SWI9X30C_02.33.03.00 (latest Verizon fw)

Only testing on one device so far.

When getting the fw version, i noticed Skylight is reporting the module Serial Number (ESN) as 0

[jyijyi]

how about disabling the rmnet or MBIM interface in AT!USBCOMP?
this is to ensure no host platform is using the data connection

BTW, is your VZW SIM card OK to establish data connection?

[e.gradine]

@jyijyi

AT!USBCOMP?

AT!USBCOMP? returns ERROR

Skylight shows a connection and data upload/download.
