Hi there,
I'm trying to use a TLS encrypted LTE-M connection for exchanging some data. The error that occurs is:
(SSLClient)(SSL_ERROR)(m_start_ssl): Failed to initlalize the SSL layer
(SSLClient)(SSL_ERROR)(m_print_br_error): Incoming protocol or record version is unsupported.
For hardware I'm using a Portenta H7 with the Portenta Cat M1 NB-IoT GNSS Shield attached.
The shield uses a CX62 chip and for software I use the arduino-core GSM library.
Is this a known issue and are there plans to support the protocol in the future?
