 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.
 
-In this tutorial we will go through the steps on how to setup both the Linux and Arduino side. 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.

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.

 ## Instructions
 
-To showcase the ability of the Linux layer and Arduino layer extended by M4 Core, we will build a mult-protocol gateway that will receive MQTT protocol packets using EMQX as the broker, retrieve the data from a local sensor attached to Portenta via RPC mechanism, wrap the data together and send to The Things Netowork using LoRa connectivity within Cayenne Low Power Payload Encoder.

 This will help you get a better understanding of how the Portenta X8 and the Portenta Max Carrier helps you develop a multi-protocol gateway.
 
 ### Hardware Setup 
 
-First things first, we will need to configure the hardware to be able to develop and work on the Multi-Protocol gateway. We will attach the Portenta X8 to the Portenta Max Carrier with High-Density Connectors, and we will make sure to attach an antenna for LoRa connectvity. The Portenta X8 also needs to have the WiFi antenna attached to it.

 ### Setting Up The Things Network
 
-We now have the pre-requisites for the Portenta X8 ready, but as we are using the LoRa connectivity, we will need a platform that has the capability to receive data transmitted from the Portenta X8 and Max Carrier. **The Things Network** will be the platform we are going to use communicate using LoRaWAN. On the platform, we will need to create an application to add the Portenta Max Carrier as an End-Device.

-When adding the End-Device, at the moment we will have to use the **Manual** option. The Portenta Max Carrier will be added under Arduino SA in the near future to be included in the LoRaWAN Device Repository. The LoRaWAN version and parameters compatible with the Portenta Max Carrier are as follows. The frequency plan will depend on the region in which you are going install the device.
