I’m trying to open a TCP socket over SSL/TLS in order to use MQTT protocol on it.
Here below the sequence of AT commands:
Modem clock has been set via
If inside KTCPCFG command is 0 (client), TCP connection never works even if the certificate has been correctly stored. If is 3 (secure client), TCP connection always works even if I delete the certificate.
How to correctly setup a TCP over SSL socket with server authentication? Sequence of AT commands of a full working example should be really appreciated.
Thanks in advance,
