Release Notes for ZentriOS-WL-1.1
ZentriOS-WL-1.1 contains a restricted set of the commands and variables available with ZentriOS-W and ZentriOS-WZ. This edition supports the AMW007 Spectre.
ZentriOS-WL-1.1 provides a number of fixes and improvements, and adds several new commands and variables with support for HTTP and OOB (Out-Of-Band) interrupt features.
New HTTP commands allow POST and HEAD requests, adding headers to requests to supply additional information, and reading the status of request responses.
You can set the 404 response page for the device HTTP server.
OOB interrupts are supported for TCP server connected and TCP client data ready events, via system.oob variables.
ZentriOS-WL-1.1 does not support TLS, except in OTA operations.
