Chapter 9
Version 3 vs. Version 2
If you are migrating from using the version 2 (second generation) of Serial Port
Adapters from connectBlue to version 3 there are some AT commands/events that
have been changed, added or removed. Each AT command description will include
a table to clarify what the differences are (if any) between different models.
Specifically some version 3 models (cB-OEMSPA311, cB-OEMSPA331, cB-
OEMSPA312, cB-OEMSPA332) do not support multipoint connections. Hence wire-
less multidrop is not supported.
