Hey I will try,
The AT commands for the BC660K are documented in a file named Quectel_BC660K-GL_TCP(IP)_Application_Note_V1.0.pdf.
The ping command is the same with BC66 but I used the wrong contextID. This worked for me:
AT+QPING=0,“x.x.x.x”
If you want DNS resolution, you have to configure it first, read the docs at chapter 2.3.8. I didnt try that myself.
The QIOPEN command is different to BC66, best to read the docs but this worked for me:
AT+QIOPEN=0,0,“UDP”,“x.x.x.x”,15683,1001,1

Hope this helps
Daniel

Fixed: The AT commands for this module are slightly different for this chip.

Hello,

I have problems sending/pinging to your server, can you assist?
I am using a BC660K-GL Dev Kit for the first time and was using the BC66 Dev Kit before which worked fine.
It is registered and is assigned an IP.
Debug Output:

+IP: 10.0.5.169

Update:
The SIM Card was not activated. Now I was able to connect to the Network.
But now, as others mentioned, I cant get the ‘last payload’ in the GUI. I will wait for an update in other posts.

Hi,

As I am trying to attach the BC66-T-BE DVK to the NB-IoT network, the device doesn’t get an IP assigned. Here is some debug output, that shows, that the setup is ok so far, but AT+CEREG? goes from “trying to attach or searching” to " Not registered" after about 10 seconds. Setup was successful and no errors while reading the IMEI. Any suggestions? Location is east Germany.
