## What is Eola Power?

Our app offers a seamless solution for connecting modern technology with legacy RS232 interfaces. Acting as a Bluetooth-to-RS232 proxy, it eliminates the need for outdated computers with physical DB9 or DB25 ports.



As modern computers and mobile devices no longer come with RS232 ports, our ecosystem bridges the gap, enabling RS232 communication wirelessly through Bluetooth. This means no bulkier USB-to-RS232 adapters or older laptops, providing users with a compact, efficient way to connect, monitor, and manage RS232 devices directly from their phones or newer computers.



Whether you're working with industrial machinery, specialized hardware, or legacy systems, our app ensures compatibility with modern devices, allowing you to continue using RS232 equipment without sacrificing convenience. By expanding compatibility to mobile devices, this solution also opens up new possibilities for interacting with legacy equipment in ways that weren't previously possible, making RS232 communication easier and more accessible.
