... Figure 3: Wi.232EUR Networking Concept The module is designed to interface directly to a host UART. Three signals are used to transfer data between the module and the host UART: TXD, RXD, and CTS. TXD is the data output from the module RXD is the data input to the module. CTS is an output that indicates the status of the module’ ...

... If this technique is used, the volatile registers will reset to the values in their non-volatile mirrors, so any changes from the default will have to be reloaded. The Wi.232EUR is a very flexible module because of all of the configurable parameters it supports. However, modules that are not configured in the same way will not be able to communicate reliably, causing poor performance or outright failure of the wireless link ...

... Figure 10: Command and CMD Pin Timing 9.2. Command Formatting The Wi.232EUR module contains several volatile and non-volatile registers that control its configuration and operation. The volatile registers all have a non-volatile mirror register that is used to determine the default configuration when power is applied to the module. During normal operation, the volatile registers are used to control the module ...
