	471	+Once all the data has been uploaded to the TTN platform, the subsequent step involves concatenating each packet in sequential order and saving it into a new TXT file. It is important to note that the first 8 bytes of each packet should be removed before concatenation.
466	466
	473	+When you combine all the packets, you need to convert the data inside to binary. Here the conversion is demonstrated using the [[WinHex>>http://www.x-ways.net/winhex/index-m.html]] software.
