Examples / Demo List

Simple Serial Socket

This is a UART over BLE bridge example where a Simple Serial Socket Client (SSSC) and Simple Serial Socket Server (SSSS) connect with one another and exchange UART data over the air. An generic Simple Stream Service is used making it easy to exchange data sink and source to create a custom serial socket over BLE implementation.

Note: this example replaces the SPP over BLE example
