AT command - error 922 using HTTPS server

There should be no problem on using AT+KCERTSTORE:

HL7802 AT+KCERTSTORE error

I was using hardware flow control. It seems that it needed both a CR and the KPATTERN at the end and it works fine but with AT+KCERTSTORE=0,1339,0 (not 1337) So this is inaccurate? [data] thanks
