313 +To get the AIS current image on the PC, you can  connect AIS to your PC with TTL to send commands through the serial port to obtain relevant data packets.

316 316  
317 -**Step 1**:  Create a device in TTN V3 with the OTAA keys from AIS Sensor.
317 +Select the corresponding baud rate and serial port number through the serial port tool, select HEX display and HEX send, and continuously receive data from the AIS Sensor
318 318  
319 -Each AIS Sensor is shipped with a sticker with the default DEV EUI as below:

321 +In the serial port to send data C0 5A 00 00 00 00 04, and then send C0 5A 00 00 00 00 09, AIS Sensor will send a real-time image of the data packet, and then stop sending. Start with FFD8 and put it in TXT file
322 322  
323 -Enter these keys in the LoRaWAN Server portal. Below is TTN V3 screen shot:

329 -Add APP KEY and DEV EUI
328 +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.
