118 Enter the IMEI (DEV EUI) of the upgraded device, enter the password (PIN), click "SELECT UPGRADE FILE" to find the file you want to upgrade**(The firmware upgrade file format only supports .bin files)**, and then click "START". While waiting for the upgrade, let the device reset once. If it keeps stopping on the download screen, you can try pressing the reset button of your device.**If the user does not wish to open the casing, they can press and hold the KEY until the device flashes a green light; this action is equivalent to pressing the reset button.**
119
120 **Note: The password check function will only take effect if the DRAGINO NB bootloader is v1.3. If the version is earlier than 1.3, whether the password is entered correctly does not affect the NB upgrade.**

140 (% class="lead" %)
141 (% style="color:blue" %)**Step1:**(%%)** Connect a BLE USB to TTL Host into PC**
142
143 Below is the example BLE to USB TTL adapter. Insert it to PC

148 (% class="lead" %)
149 (% style="color:blue" %)**Step2:**(%%)**  Modify Bluetooth host parameters to support Dragino Sensor Management Tool** **v1.4**
150
151 The default baudrate of the general Bluetooth host is 9600, we can use the three commands: **AT+BAUD7; AT+TIMEINQ40; AT+RESET** to change the baudrate of the Bluetooth host to 115200, in order to support the use of Dragino Sensor Management Tool V1.4 to download the firmware faster.
152
153 If your Bluetooth host's baud rate is already 115200, please refer to (% style="color:blue" %)**Step3**(%%) directly.
154
155 * Check if the Bluetooth host is functioning properly.
156
157 Open the serial assistant and send **AT+INQ** (remember to bring carriage return and line feed).
158
159 Seeing this interface proves that the host is working properly:
160
161 [[image:image-20240912174330-9.png||height="528" width="674"]]
162
163 * Connect to Bluetooth host through serial port and send **AT+BAUD7; AT+TIMEINQ40; AT+RESET** successively, confirm that each command returns OK, and finally disconnect the serial port connection.
164
165 An example diagram is as follows:
166
167 [[image:image-20240912174428-10.png||height="554" width="704"]]
168
169 (% style="color:red" %)**Note:**
170
171 (% style="color:red" %)**1. Because the baudrate of the unmodified Bluetooth host is 9600, the serial port baud rate needs to be selected 9600 when sending the above three instructions.**
172
173 (% style="color:red" %)**2. These commands need to be used only once. After successful modification, the Bluetooth host baud rate is changed to 115200 and this change is maintained.**
174
175 * If the serial command sending fails, please modify the sending settings of the serial assistant as below:

188
189 (% style="color:red" %)**Note: Before upgrading, it is necessary to ensure that the baud rate of the Bluetooth host is 115200(Refer to Step 2).**

192
193 [[image:image-20240912165247-1.png]]
194
195 * Before clicking "Start", make sure that the switch of the node is in **FLASH**.

197 [[image:image-20240912170209-3.png||height="351" width="616"]]
198
199
200 * Click "Start", then reset the node, and the node's Bluetooth will turn on. Dragino Sensor Management prints the Bluetooth information searched by the Bluetooth tool.
201
202 The following screen indicates that the Bluetooth host has successfully connected to the node and started the upgrade

209 1. (% style="color:red" %)**If the node has been restarted before the upgrade, wait two minutes before the upgrade.**
210 1. (% style="color:red" %)**The Bluetooth of the node will be enabled for 8~~15seconds. If the operation is not timely, reset the Bluetooth tool and node again.**
211 1. (% style="color:red" %)**Ensure that the IMEI entered is correct, and the firmware upgrade will only be performed when the Bluetooth host scans the Bluetooth of the corresponding node.**

233 == 5.1 What should I do if the upgrade process is automatically interrupted? ==
234
235
236 Example:
237
238 [[image:image-20240912172143-6.png||height="445" width="460"]]
239
240 **How to operate:**
241
242 1. After the upgrade is interrupted, you need to close the wireless upgrade tool and reopen it later.
243
244 2. Before restarting the upgrade, you need to reset the Bluetooth host, otherwise the upgrade may not be possible.
245
246 * If your Bluetooth host has a RESET button, you can use the RESET button to reset it.
247 * If your Bluetooth host does not have a RESET button, you can directly unplug the Bluetooth tool from the computer to power it off, and then reconnect it to the computer.
248
249 == 5.2 Why does the node keep resetting even though the firmware upgrade is successful? ==
250
251
252 If the user burns the firmware with a boot loader, the following situation may occur.
253 Therefore, users need to select firmware without boot loader when burning firmware.
