AT+QHTTPPOST is not working

IoT Modules GSM Module
1

I have been using M66 for a while and I’m trying to post some JSON data to Firebase but it is showing error +CME error 3804 everytime.

The AT commands that I used are,

AT
AT+CPIN?
AT+CREG?
AT+CFUN=1
AT+QIFGCNT=0
AT+CGDCONT=1,"IP","WWW""
AT+CGATT=1
AT+CGACT=1,1
AT+CGPADDR=1
AT+QIFGCNT=0
AT+QICSGP=1,"CMNET""
AT+QIREGAPP
AT+QIACT
AT+QHTTPCFG="contextid",1"
AT+QHTTPCFG="requestheader",1"
AT+QHTTPURL=107,50

serial.print(“https://firebaseserverurl.json”)

AT+QHTTPPOST=10,60,60

serial.print({“age”: “30”,“name”: “John”})

What exactly leads to this error and how can I fix this error?

Hi
This error means that you did not send http get or post request, please make sure that normal get and post can be executed, if only json reply exception, maybe the server or module does not support this protocol
