The Proteus-III is a Bluetooth
LE module based on the nRF52 Nordic Semiconductors SoC which presents various Bluetooth LE and low power features.
It provides a command based UART interface that allows the configuration and control of the Proteus-III by simple commands.
Besides the commands needed for configuration and radio data transmission, various commands are provided to use the so called remote GPIO feature.
This feature allows to write and read up to 6 GPIOs of the Proteus-III via Bluetooth LE connection. With help of this, simple applications, like switches or digital level detectors, can be realized with the Proteus-III without the need of connecting a host controller to it.
This application note describes which steps have to be run to switch a GPIO and how to read the pin level of a GPIO via remote connection.
First or all a general description follows, then in the Examples section it is demonstrated how the GPIOs can be controlled by a second Proteus-III radio module or by smart phone.
