Hey all,
I am trying to connect a Quectel BG96. Every time after configuring

AT+COPS=1,2,"20416",9

It says

CME Error: 13

Also a simple command to retrieve the IMSI AT+CIMI gives an error then.

When I reset the modem and use AT+CIMI again, it works and returns the IMSI. However, after trying to configure the COPS again, the error comes back…

Any ideas?

Hi @uta, thanks for the tip. You’re right, I was using the wrong APN for the type of SIM I have. I have an easy connect SIM, and for that the APN should be just “iot.t-mobile.nl” it turns out (without the CDP bit). Now the UE attaches & registers to the network perfectly fine :D

This is strange. Let’s do some further checks with our colleagues. Does @Florian-Duecker already have the full IMEI? If not, @Yosiel can you pls send it to me via dm or afzal@iotcreators.com

@HaraldNaumann maybe you’ve got some advice?

Before activating radio module Set APN with AT+QCGDEFCONT rather than **AT+CGDCONT Set frequency band explicity with AT+QBAND Configure first APN, fequency band and mobile operator ID before switching on automatic attachment

@Rasyid Do you have a valid network connection ?

For Quectel BG96 you can verify the network connection with the following AT commands

AT+CGPADDR //check IP address AT+CGATT? //check if attached to network AT+COPS? //check current set MNO AT+COPS=? //scan network for mobile operators AT+CGDCONT? //check APN AT+QPING=1,"172.27.131.100" //ping UDP server

Hi Thorsten,
thanks a lot for your reply. I will test the things you suggested but it might be a few days until I reply here with the results.

The problem is, I bought this from a private person used on ebay. I hope they answer next week on my mail.

To be continued. Already needed a link to make a QR code for the flyer with instructions :-)

@Yosiel

That is great. Just reach out when you need assistance again. :-)

@Wessam Hi, have a look to https://forum.iotcreators.com/topic/626/how-long-does-it-take-that-the-network-detects-a-dead-ip-connection. Maybe it contains some info you are interested in.

Regards, Roland

@Tuyen-Phan I have mailed support@iotcreators with the imei number.

For the final reply, the datas that are being sent to beeceptor are forwarded to the HTTP endpoint in Turkey. I entered the url of the server In Turkey to the proxy settings on my beeceptor page. So now the problem is handled. Thank you everyone.

Kind regards,
Mert

Hi Karl,
our network department is investigating this issue. We’ll get back at you asap.

@Florian-Duecker I am using T-Mobile NB IoT sim card. I already sent you the ID of the sim card so you are suggesting me to order a new sim card from link you sent? I’ll check it.

Cool Project. I would like to thest the device in Germany.

Unfortunately it didn’t work out, what we tried yesterday. Please follow this topic for new updates.

@Roalnd-Baldin Cool! Nice to see it works now.

Edit:
Just after posting, I struck upon this topic and was able to succesfully connect.
Now I’am figuring out how to setup the socket and start sending Hello world! messages.

I will do my best to keep you updated!
