EC20 AT+CGACT=1,1 always return error

[Madhav]

Hello,

I am testing an EC20 module for MQTT transmission. List of commands that I am following:

AT+CGDCONT=1,"IP","www"
AT+CGACT=1,1
AT+QMTCFG="recv/mode",0,0,1
AT+QMTCFG=“SSL”,0,1,0
AT+QMTOPEN=?
AT+QMTOPEN=0,"<broker url>",8883
AT+QMTCONN=0,"clientExample","id","password"
AT+QMTPUBEX=0,0,0,0,"test",12

This used to work, but then AT+CGACT=1,1 started giving output “ERROR”. The sim used here is a Vodafone postpaid Sim.

ATI
Quectel
EC20F
Revision: EC20CEFDLGR06A04M1G

OK

AT+CGDCONT?
+CGDCONT: 1,"IP","www","0.0.0.0",0,0,0,0
+CGDCONT: 2,"IP","","0.0.0.0",0,0,0,0
+CGDCONT: 3,"IP","","0.0.0.0",0,0,0,0

OK
AT+CGACT=1,1
ERROR
AT+CGPADDR=1
+CGPADDR: 1,"10.69.228.49"

OK
AT+QMTCFG="recv/mode",0,0,1
OK
AT+QMTCFG=“SSL”,0,1,0
ERROR

Though I am able to send data via MQTT without SSL even though AT+CGACT return error.

AT+CGACT=?
+CGACT: (0,1)

OK
AT+CGACT?
+CGACT: 1,1
+CGACT: 2,0
+CGACT: 3,0

OK
AT+CGACT=0,1
ERROR
AT+CGACT=1,1

Hi – Can you check if the module has successfully registered with the network using the the AT+CREG command?
