Hello,
Our devices are connecting to AWS Iot Core using MQTT.
In the firmware we have Keil MDK 8.1.0 and mbedTLS 3.6.4.
We have few complaints from customers with poor connection. Occasionally the device didn't reconnect, only a reboot would fix the problem.
On the Wireshark logs we have identified 2 errors:
- close notify from server after client hello
- bad certificate from client after server hello
Apparently the TLS library was stuck at one of these errors and only a reboot could fix them.
Not sure if both errors are related.
Anyone had these issues before?
If someone could help I would give more details.
Regards,
Milo
