9160 Serial lte modem at command question

[William.wei]

hi support team,

customer is asking how to add keep alive time in https request header,

i was trying to do this command as below: adding "Keep-Alive: 60\r\n" in XHTTPCREQ, but since this is https, i am not sure if this is correct

customer is using mfm1.3.0 or 1.3.1 and ncs is 1.6.0 or 1.6.1. and command format should not a problem.

AT#XHTTPCREQ="POST","/post.aspx","HOST:app.coordinationcentric.com\r\nKeep-Alive: 60\r\nContent-Type: application/json\r\nContent-Length: 165\r\n",165

by the way HOST should not include in the header, right?

Regards,

William.

Thanks Michal,

i have another question, why our 9160 signal  rsrq is jumping from 33 to 20 and not so stable?

i don't know why and is it important for 9160 communication?

customer want to use rsrp as one stander of the device signal level
