1.3 Disclaimer
There are two known issues with the SSL/TLS stack in the NL-SW-LTE-QBG96:
1. It does not validate the hostname in the server certificate.
2. It does not validate X509v3 Extended Key Usage for the end certificate in the chain.
Because the SSL/TLS stack does not validate the hostname, the device will trust any host
with a certificate signed by same global CA (certificate authority) if IP traffic is redirected
to that server.
The module manufacturer is aware of these issues, and is currently working on a fix that
we expect will be available in a future firmware release.
You may use the built-in SSL/TLS stack on the NL-SW-LTE-QBG96 knowing these
limitations, however at this time NimbeLink recommends using an external SSL/TLS stack
on your host processor to handle the connections, such as mbed TLS:
or WolfSSL:
NimbeLink does not provide support for integrating these SSL/TLS stacks.
