Hello support,
I followed the instructions on doc.airvantage.net/av/howto/har … g_started/ to register my HL8548 modem to the AirVantage platform.
The device has been added to my systems, but I seem not to be able to successfully register the device through the AT+WDSS command (refer to attachment reg_airvantage.png). I follow the following sequence. My SIM card is from a Belgian operator, has data enabled and activated, I use AT+CGDCONT? to check if I received an IP address.
AT+WDSS=0,"internet.proximus.be"
OK
AT+WDSS?
+WDSS: 0,"internet.proximus.be"
+WDSS: 1,0
OK
AT+WDSI=8191
OK
AT+WDSI?
+WDSI: 8191
OK
AT+WDSS=1,1
OK
+WDSI: 4
+WDSI: 7
AT+CGDCONT?
+CGDCONT: 1,"IP","internet.proximus.be","0.0.0.0",0,0
+CGDCONT: 5,"IP","internet.proximus.be","100.73.211.184",0,0
OK
AT+WDSS=1,0
OK
AT+CGDCONT?
+CGDCONT: 1,"IP","internet.proximus.be","0.0.0.0",0,0
+CGDCONT: 5,"IP","internet.proximus.be","0.0.0.0",0,0
OK
FYI:
at+kgsn=1
+KGSN: 3595150587670511
OK
at+kgsn=3
+KGSN: HD649706230110
OK
Any clues?
regards,
Stephan
Hi Stephan,
you have configured your device but you didn’t open a session with AirVantage.
You have to do the following with the result:
at+wdss=1,1
OK
+WDSS:4
+WDSS:6
+WDSS:8
if you have code 7 instead of 8, an error occurred. 8 means successfull (see HL AT command guide for more information)
Regards,
Robert
Hi Robert,
If you scroll down the code snippet from my original post, you can see I did actually issue the AT+WDSS=1,1 command. I received the error code 7:
AT+WDSS=1,1
OK
+WDSI: 4
+WDSI: 7
So in my opinion, it seems that something goes wrong with the registration. I have mode some other tests (try to create TCP and HTTP connection), and they all succeed, so the SIM card has surely data enabled.
regards,
Stephan
Hi Stephan,
sorry, I didn’t see I could scroll down
I checked your configuration on AirVantage, all is fine. The module has never communicated with AirVantage. So the issue should come from the credentials provisioned in the module. Sometimes, I saw trying several times at+wdss=1,1 it can work but I can only tell you to contact your reseller’s support team so far.
Regards,
Robert
OK tnx, I will contact our FAE.
Hi,
Did you find the reason that made the registration failed? When I use hl7692 to connect AirVantage, I have WDSI 7 too.

Hi, this was for a prototype project only, which was not further developed. So, I can’t help you further.
