1 Introduction
1.1 The ASR6505 is a LoRa soc chip. The interior is implemented by ST 's 8bit
low power MCU STM8L152 packaged with Semtech' s LoRa transceiver
SX1262 . The module can achieve 868(for EU)/ 915Mhz frequency band
communication. The module implements the LoRa device with CLASS
A,B,C protocol. The module provides a serial port AT instruction set for
MCU calls and 2 IO for wake up between MCU.
The module’s maximum receiving sensitivity is up to - 140dBm,
maximum transmit power up to -2.75dBm.
