HTTP and TCP commands not working : Operation not permitted

IoT Modules Legacy HL Series
1

Hello,

I am struggling with HL7800 module that we are integrating into our product.
The UDP communication works just fine but when it is time to talk HTTP, it says operation not permitted.

Can you check what is going wrong?

Here are the logs of the commands sent manually.

AT+COPS?
+COPS: 0,0,“Verizon Wireless”,7
OK

AT+KCNXUP=1
+CME ERROR: 910

AT+KCNXDOWN=1
OK

AT+KCNXUP=1
OK
+KCNX_IND: 1,1,0

AT+KHTTPCFG=1,“www.google.com”
+CME ERROR: operation not supported

AT+KTCPCFG=1,0,"www.google.com,80
+CME ERROR: Operation not allowed

What am I doing wrong here?

Let me know.

Thank you.

Hi,
The HTTP command is correct, what is the current firmware?
For the TCP command, you are missing " . It should be AT+KTCPCFG=1,0,“www.google.com”,80

Thanks,

Hi,
HTTP command is not implemented on your firmware, please update to the latest fw
https://source.sierrawireless.com/resources/airprime/software/hl7800-firmware/hl78xx-firmware/#sthash.kQLNpsL5.dpbs
For fw 1.7.15 you only use TCP and UDP ( not HTTP, FTP).

Thanks,

Hi Jerdung,

I have updated the modem with the HL7800/HL7800-M Firmware Release 3.7.2.3. This update I guess broke a lot of things. AT+CMEE=2 doesn’t work. It returns with
AT+CMEE=2
+CME ERROR: 3

I have been trying to connect it to the network and so far there have been no success.
Is 3.7.2.3 a stable release?

AT+COPS=0 gives a timeout or error 515 or PLMN Busy which is not listed in the at command document.
Lot of issues.

Thank you.

Hi,
Sierra is aware of this issue. There are some changes of this FW so we can not upgrade directly from 1.7.15 to 3.5 (3.7.2). The fix may be available in the next build.
Please fall back to FW 1.7.15 and use TCP instead of HTTP.
Or please contact your distributor to get the instruction of upgrading.
Sorry for this inconvenience.
Thanks,

Hi Jerdung,

I will then need help with two things from you.

  1. Can you provide me with the link to the 1.7.15 version. The download link lists only two of them.
  2. Can you guide me with the set of commands I can use to make https post requests with TCP commands?

Thank you.

Hi aditya,
I tried to re-update device with fw 3.5.0 and it is working. For this FW, CMEE mode 2 is not supported, you can find new document https://source.sierrawireless.com/resources/airprime/software/airprime_hl78xx_at_commands_interface_guide/#sthash.e2xJ88fp.dpbs
Please try to set APN and reset module.

Thanks,
