Automatic DIP Switch Configurations
Each time the module assembly is powered-on, AT commands are sent to the on-board RF module
as dictated by the positions of the DIP switches. DIP switch configurations are sent automatically
during the power-on sequence and affect module parameter values as shown in the table below.
