User Manual of SRM200A(Rev1.0)
1. Introduction
The SRM200A is a quad mode module supporting Sigfox, BLE, WiFi and GPS.
This Module able to transmit and receive messages using the SIGFOX network.
The typical applications can be used as a low power tracking device.
The application use WIFI or GPS to determine location. It will then transmit the location information via SIGFOX.
It also will transmit other information like temperature, accelerometer, and so on.
