Troubleshooting +CME ERROR: 921 during HTTPS POST on HL7800

Hi,

AT+CGATT=0

OK

AT+KCNXUP=1

OK

+KCNX_IND: 1,4,1

+KCNX_IND: 1,2,1,2,30

AT+KHTTPCFG=1,“api.sandbox.ewaypayments.com”,443,2,0

+KHTTPCFG: 1

OK

+KCNX_IND: 1,4,1

+KCNX_IND: 1,2,1,2,30

AT+KHTTPPOST=1,“/DirectPayment.json”,1

+CME ERROR: 921

+KCNX_IND: 1,4,1

+KCNX_IND: 1,2,1,2,30

The HL7800 cannot bring up PDP connection after network detachment in your log file. It has not supported this behavior. So you should remove AT +CGATT=0 command.

Here is result on my module:

AT+KHTTPPOST=1,,"/DirectPayment.json",1

+KHTTP_IND: 1,1

CONNECT

NO CARRIER

+KHTTP_ERROR: 1,6

Please find the log file for your reference.KHTTPPOST_api.sandbox.ewaypayments.com.txt (2.8 KB)

For issue NO CARRIER, +KHTTP_ERROR: 1,6 after KHTTPPOST with api.sandbox.ewaypayments.com server. It does not work for headers that may contain many fields. It can be limitation of the current firmware module. I hope new firmware release will be updated to fix the issue.
