Espotel / Mbed 2 deprecated Elmo-Terminal-App

Elmo Terminal provides functionality to test Lora radio and access SX1272 chip registers delivered with Elmo board. This firmware allows the user to control the LoRa radio parameters (eg. frequency, bandwidth, spreading factor etc.) by entering console commands via serial terminal. Application also contains "Ping-Pong" and data transmission functionalities.

Dependencies:   SX1272lib mbed
