SP1ML modules getting started guide FW upgrade & simple
communication setup
Introduction
This document is a quick user guide explaining how to upgrade the FW in ST sub-GHz
modules SP1ML-868 and SP1ML-915 (hereafter referred to as SP1ML), and evaluation
tools STEVAL-SP1ML868 and STEVAL-SP1ML915 (hereafter referred to as STEVAL-
SP1ML).
It also provides a possible setup to quickly establish communication between two modules
using AT commands.
The SP1ML-868 and SP1ML-915 are complete RF modules based on the SPIRIT1
transceiver with integrated voltage regulation, antenna, crystal and STM32L1
microcontroller, in a compact surface-mount module form-factor.
The UART host interface allows simple connection to an external microcontroller.
Access to module features is provided through an extended AT command set.
