3.17 Software Development
Espressif provides several software tools and frameworks. This chapter gives an overview of
the major software components Espressif IoT Development Framework (ESP-IDF) and
Espressif AT-Software (ESP-AT).
3.17.1 Espressif IoT Development Framework (ESP-IDF)
The PAN9520 is a radio certified module. There are conditions on hardware
and software which must be met for the modular approval to be valid.
For detailed information please refer to
“PAN9520 Module Integration Guide”.
Espressif provides the IoT Development Framework (ESP-IDF) for software development. This
includes a multitude of examples that can be used as starting point for the software
development.
Software, general information, and instructions are provided by Espressif on e.g. following web
