410 +=== 3.2.2 Combined image ===
411 +
412 +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.
413 +
414 +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.
415 +
416 +Open WinHex to open the combined image data file.
