Hello
I’m using a BC660K-GL module with NB-IOT sim card. I have managed to connect to the network. Here’s my configuration and module software version info:
ATI<\r><\n>
Quectel_Ltd<\r><\n>
Quectel_BC660K-GL<\r><\n>
Revision: BC660KGLAAR01A05<\r><\n>
OK<\r><\n>
AT+QCGDEFCONT?<\r><\n>
+QCGDEFCONT: "IP","INTERNET",,,,1<\r><\n>
OK<\r><\n>
AT+CGDCONT?<\r><\n>
+CGDCONT: 0,"IP","NBIOT","10.172.2.163"<\r><\n>
+CGDCONT: 1,"IP","INTERNET"<\r><\n>
OK<\r><\n>
+QNBIOTEVENT: "ENTER PSM"<\r><\n>
Is this revision up to date? I need to know this because I’m having an issue with HTTPS requests. However, I can make HTTP request just fine which is supported by the device:
at+qhttpurl=71>> <\r><\n>
OK<\r><\n>
+QNBIOTEVENT: "EXIT PSM"<\r><\n>
+CSCON: 1<\r><\n>
at+qhttpurl?<\r><\r><\n>
+QHTTPURL: http://web.simmons.edu/~grovesd/comm244/notes/week3/html-test-page.html<\r><\n>
OK<\r><\n>
+CSCON: 0<\r><\n>
at+qhttpget=60,60<\r><\n>
OK<\r><\n>
+CSCON: 1<\r><\n>
<\r><\n>
+QHTTPGET: 0,200,4507<\r><\n>
This works as intended. But, whenever I make a get request to google or any other website with HTTPS, I end up with an error:
at+qhttpurl=23>> <\r><\n>
OK<\r><\n>
at+qhttpget=60,60<\r><\n>
OK<\r><\n>
+QHTTPGET: 716<\r><\n>
at+qhttpurl?<\r><\n>
+QHTTPURL: https://www.google.com<\r><\n>
Does this device not support HTTPS requests? What should I do with my current configuration? Is there a revision that supports HTTPS requests? I cannot change the http content type configuration (default value is 0).
Here’s additional info for my current configuration just in case:

We’re planning to buy BC660K-GL in bulk, so your help would be much appreciated. Please let me know what’s missing as soon as possible.
Here’s what happens when I follow the instructions:
AT+QSSLCFG=0,0,"seclevel",1<\r><\r><\n>
OK<\r><\n>
AT+QHTTPCFG="ssl",0,0<\r><\r><\n>

<\r><\n>
+QHTTPGET: 716<\r><\n>
at+qhttpread=60,60<\r><\r><\n>

Any ideas why this fails? 716:HTTP socket connect error
at+qhttpget=60,60<\r><\n>
OK<\r><\n>
<\r><\n>
+CSCON: 1<\r><\n>
+QHTTPGET: 716<\r><\n>

OK<\r><\n>
Same result
Is Revision: BC660KGLAAR01A05 up to date?
I’ve worked with Quectel M66 device and it can successfully make requests when https is included. Is there a way to set these parameters on BC660K-GL so that we can make sure the configuration is correct? @herbert.pan-Q
My configuration for M66 was:
AT+QSSLCFG="sslversion",1,2
AT+QSSLCFG="seclevel",1,0
AT+QSSLCFG="https",1
AT+QSSLCFG="httpsctxi",2
AT+QSSLCFG="ciphersuite",1,0X0035
AT+QHTTPCFG="sslctxid",1
According to my validation tests, you need to import google’s public CA certificate, and I recommend that you use other urls for testing

I’ve added pem certificate of the url:

-----BEGIN CERTIFICATE-----
<<_.us-central1.firebasedatabase.app PEM certificate>>
-----END CERTIFICATE-----

I have tried other urls such as https://webhook.site/bcaddbe8-41b6-444d-9127-51dcbf896358 , Best String to Hex Converter Online to Convert Text to Hex. and https://www.google.com/ with no avail. Can you send me a link that works to test? Is there a certificate for the example link you’ve provided, too?
Edit: I’ve tried loading up the https://www.example.com/ pem certificate and it did not work as well. Could you direct me to the technical support if possible @herbert.pan-Q ? Why is this not working as intended?
This is from the hardware specifications Quectel_BC660K-GL_Hardware_Design_V1.3-1.pdf:
Maybe my revision is not up to date? Or am I supposed to use a different configuration such as NB category = 2, relversion= 14?
@herbert.pan-Q
no,no,If you grab the debug log and look at the data flow, you may be able to understand more about the cause of the failure

Could you tell me how to log the device so that I can solve the problem? I’ve connected RX/TX to the uart port and powered up the module using 3V. Do I need a different configuration to log or how can I achieve that?
Is the evaluation kit necessary for that @herbert.pan-Q ? I don’t have the TE-B kit
I need the EPAT.exe file. Could you provide me the file while I arrange debug pins for this device?
I have sent them to you,pls check

Thanks for the log application. I think I need a DB file to update but I can’t find it. This is all I see after applying AT+ECPCFG=“logCtrl”,2.
Where can I get DB file from?
@herbert.pan-Q my module’s version is BC660KGLAAR01A05
I have sent it to you,It is included in the firmware package

Hi @herbert.pan-Q .
My current revision is BC660KGLAAR01A05_01.200.01.200. I could not update my device with the provided latest version/DB file. So I tried logging the device directly by updating DB only.
When I update DB with BC660KGLAAR01A05_01.202.01.202 firmware, I see this error on my logs when applying log control command:
And I cannot see events in the log. So, could you instead send me a compatible DB file with my current revision BC660KGLAAR01A05_01.200.01.200?
(I have tried changing my baudrate to 921600 as configured in the memory)
I make HTTPS request to https://www.google.co.uk/ link. I have the log zip file attachment:
20240506_114002.zip (327.9 KB)
AT LOG:
at+qhttpurl=25
>
OK
at+qhttpget=60
OK
+QHTTPGET: 716
So what does "gQSSLList is null mean?
