ESP32 aws_iot subscribe/publish example error

Postby raemond » Tue Aug 01, 2017 1:56 am

Hi

I can't seem to get the aws_iot examples to work. On my latest attempt, I am working with the subscribe publish example. I am continually getting:

Code: Select all

I (4692) subpub: Connecting to AWS...
I (11722) wifi: pm start, type:0

E (33342) subpub: Error(-28) connecting to asdf.iot.us-west-2.amazonaws.com:8883
E (60352) subpub: Error(-28) connecting to asdf.iot.us-west-2.amazonaws.com:8883
E (72222) aws_iot: failed! mbedtls_ssl_handshake returned -0x6800
Seems like the connection is timing out. Has anyone seen this and figured out a solution? I believe I have everything configured correctly on the AWS side.

Thanks.

The current master branch works for me (using the default project config with only my endpoint hostname & WiFi credentials changed.)

I haven't seen this particular behaviour (TLS timeout) before, but maybe AWS has reconfigured the way that it will "hang up" on a bad connection. It will unceremoniously stop responding if there's any mismatch with your client cert & hostname, or if the Policy is set wrong. You can find some troubleshooting tips and a list of things to check, here: https://github.com/espressif/esp-idf/tr ... leshooting

I've got a similar problem to raemond ..... I've spent days working on the AWS subscribe_publish example without getting it working.
I've gone over certificates and policies, etc. and I'm pretty sure I've got them correctly configured.
Any help much appreciated .........

I get:
