- Standalone Samples
This module adds wireless connectivity, allowing for wireless control of DUELink modules. It can be used in 2 ways: Use it as a Wireless Interface Host, controling a daisylink of modules. You will be able to program and command modules over a wireless connection! The other option is to use this module within a daisylink, to provide a wireless access to the host and other connected modules.
