Hello,

I'm trying to communicate with AWS IoT using EXS82-W and MQTT but I have some questions.
I installed the 3 certificates obtained from AWS securely using the cmd_ipcertmgr.jar tool (device certificate, private key and AmazonRootCA). To install them safely I followed the document "tls_certificate_management_exsx2_v2.pdf".
To carry out communication via MQTT I am using the commands available in the document "2022_08_15_data_transfer_methods_aws_enrollment.pdf", however when executing the command AT^SISO=1,2 the service is not opened and a timed out error occurs.
I read some things about Midlet, but I didn't understand if I need to install it in this case.

ATI1
Cinterion
EXS82-W
REVISION 01.200
A-REVISION 01.000.01

java version "1.7.0_80"

Can anyone help me with this?

Thanks in advance!
