I want to establish a MQTT connection to AWS IoT using EC25, however the MQTT specification for the EC25 says:
<client_idx> Integer type. MQTT client identifier. Range: 0–5
Does this mean I can only have 6 concurrent devices connected to my broker ? Is there any workaround ?
By the way, is it even possible to connect to AWS IoT using EC25 MQTT AT commands ? Does it comply with the Server Name Indication (SNI) TLS extension rfc3546#section-3.1, security certificates, signatures and such ?
