+### Updating the LoRa® Module Firmware
+To be able to use the LoRa® functionality, we need to first update the firmware on the LoRa® modem. This can be done through Arduino IDE by running a sketch included in the examples from the MKRWAN library.
+
+1. Connect the Portenta H7 and the Portenta Vision Shield to your computer and open the Arduino IDE. 
+2. Install/update the **MKRWAN** library from Arduino IDE menu  **Tools > Manage Libraries**. Type "MKRWAN" to find the library and click 'Install' or 'Update' if necessary. This library provides all the APIs to communicate with LoRa® and LoRaWAN® networks.
+3. Open the **MKRWANFWUpdate_standalone** sketch from the Arduino IDE  menu: **File > Examples > MKRWAN**.
+
+4. Upload the sketch.

 ## Connecting to the TTN
 
 The Portenta Vision Shield - LoRa® can be connected to the TTN and can transmit data to other devices connected to this network through a secure channel. This channel is nothing but an applicaiton on the TTN network dedicated for your board. In this tutorial, you will be guided through a step-by-step process of setting up your Portenta board and the Vision Shield LoRa® to communicate with a TTN application. As stated before, to be able to follow this guide, to be under coverage of one of the TTN gateways. You can check for [the coverage](https://www.thethingsnetwork.org/map) now if you have not done so yet.
