+## Troubleshooting
 For troubleshooting the issues that might have arose following the tutorial, you can use following tips to solve the issue. 
+
 - If it logs there has been an issue with Wi-Fi module, means the device may have suffered from losing the Wi-Fi firmware partition. To solve this, you will have to use **PortentaWiFiFirmwareupdater** sketch found on Arduino IDE examples to fix the issue. 
 - QSPI storage may throw error -3 while running Portenta H7 OTA QSPI example. To fix this you can use this guide of [Reading and Writing Flash Memory](https://docs.arduino.cc/tutorials/portenta-h7/por-ard-flash/) in the section **Programming the QSPI Flash**. After this, run the example and it should have been solved by eliminating error -3 (OTA Storage initialization error).

 With the access point set up you create a client server architecture where the board provides a web server communicating with the client devices over HTTP. The connected devices can then make HTTP GET requests to the server to retrieve web pages served by the web server on the board. This makes the Portenta H7 an ideal board for developing IoT solutions where external client devices can send and receive information while more complex processing tasks take place on the server.
