Hi There
I am trying to get the MQTT ssl functionality working on my Quectel M66.
I am following the documentation and I am stuck with the AT+QSECWRITE command. See my below output. I am not sure if the length parameter of 1556 is correct. Do I include the BEGIN CERTIFICATE and END CERTIFICATE part? Please assist.
AT+QSECWRITE=“RAM:cacert.pem”,1556,10
CONNECT
+QSECWRITE: 0,0
+CME ERROR: 4009
