 ## Overview
 
-Portenta X8 has the NXP® i.MX 8M Mini MPU (Linux) and STM32H747XI dual Cortex®-M7+M4 32bit low power ARM® MCU (Arduino) stacked together and can be used to design different work loads for these two different microprocessors. We will use the Portenta Max Carriers onboard CMWX1ZZABZ-078 LoRaWAN® module from Murata®, and the WiFi connectivity from Portenta X8 to build a Multi-Protocol Gateway.

A device collecting sensor data will transfer the data via WiFi, receive the data and exchange it between the Arduino and Linux layers, to then use LoRaWAN® to finally send the information to The Things Network. We will also configure and expose a local communication lane to further expand its capability if a local sensor is desired.

 We will use a python script that will configure and handle the connectivity modules and its sensor data. The RPC calls will be used to expose the received sensor data to the Arduino layer, setting up data exchange configuration to further expand the capability of the Portenta X8 and Max Carrier. The process can also be done vice-versa if the Arduino layer is to transmit the data to the Linux layer from the local end-device.

A sensor can be attached directly communicating via Arduino layer to receive the data, wrap it, and send it to The Things Network. Meanwhile, we will also need to have a mechanism that will be able to intercept data sent over WiFi connectivity using a MQTT protocol.

You have built the gateway that will connect the The Things Network to send the desired data. Also, the gateway is capable of exchanging data between Arduino and Linux layer using RPC, in which you have exposed the ports to be able to receive data from the local sensor to be sent directly to The Things Network.

 * If the sketch upload process fails, check if your Portenta X8 is in bootloader mode. To put the Portenta X8 into Bootloader mode, double-press its RESET button and verify that the green LED is blinking. After this, you can try re-uploading the sketch for the Arduino layer.
 * Check the position of the BOOT DIP switch of the Portenta Max Carrier. If the Portenta X8 gets into bootloader mode immediately after powering-on, including when connected via USB-C, change the position of the BOOT DIP switch to OFF. This case applies to the Arduino layer.
 * If you encounter an issue regarding terminal input inconvenience, please enter `export TERM=xterm` as the command in the terminal to get readable inputs.
