56 There are two kind of firmware:
57
58 * **.bin** : original firmware file.
59 * **.hex** : file with control / meta info.

62 Please note that user needs to use (% class="mark" %)**.bin**(%%) file for update.
63
64 (% class="wikigeneratedid" %)
65 The **.bin** firmware of the -NB model products is placed in the (% class="mark" %)BC660 Wireless upgrade NB & NS firmware(%%) directory of each product.

79 = 3. How to use PC to upgrade via BLE? =
80
81
82 (% class="lead" %)
83 (% style="color:blue" %)**Step1:**(%%)** Connect a BLE USB to TTL Host into PC**
84
85 Below is the example BLE to USB TTL adapter. Insert it to PC

89
90 (% class="lead" %)
91 (% style="color:blue" %)**Step2:**(%%)**  Modify Bluetooth host parameters to support Dragino Sensor Management Tool** **v1.4**
92
93 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.
94
95 If your Bluetooth host's baud rate is already 115200, please refer to (% style="color:blue" %)**Step3**(%%) directly.
96
97 * Check if the Bluetooth host is functioning properly.
98
99 Open the serial assistant and send **AT+INQ** (remember to bring carriage return and line feed).
100
101 Seeing this interface proves that the host is working properly:
102
103 [[image:image-20240912174330-9.png||height="528" width="674"]]
104
105 * 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.
106
107 An example diagram is as follows:
108
109 [[image:image-20240912174428-10.png||height="554" width="704"]]
110
111 (% style="color:red" %)**Note:**
112
113 (% 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.**
114
115 (% 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.**
116
117 * If the serial command sending fails, please modify the sending settings of the serial assistant as below:

129 (% style="color:blue" %)**Step4:**(%%)** Update .bin Firmware**
130
131 (% 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).**
132
133 * Select the** **Dragino Sensor Management Tool parameter:
134
135 [[image:image-20240912165247-1.png]]
136
137 * Before clicking "Start", make sure that the switch of the node is in **FLASH**.

139 [[image:image-20240912170209-3.png||height="351" width="616"]]
140
141
142 * 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.
143
144 The following screen indicates that the Bluetooth host has successfully connected to the node and started the upgrade

150 1. (% style="color:red" %)**Reset the node: Hold down the ACT key for 3s or press the Reset key to reset the node, then  the node's Bluetooth will turn on.**
151 1. (% style="color:red" %)**If the node has been restarted before the upgrade, wait two minutes before the upgrade.**
152 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.**
153 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.**

175 == 5.1 What should I do if the upgrade process is automatically interrupted? ==
176

178 Example:
179
180 [[image:image-20240912172143-6.png||height="445" width="460"]]
181
182 **How to operate:**
183
184 1. After the upgrade is interrupted, you need to close the wireless upgrade tool and reopen it later.
185
186 2. Before restarting the upgrade, you need to reset the Bluetooth host, otherwise the upgrade may not be possible.
187
188 * If your Bluetooth host has a RESET button, you can use the RESET button to reset it.
189 * 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.
190
191 == 5.2 Why does the node keep resetting even though the firmware upgrade is successful? ==
192
193
194 If the user burns the firmware with a boot loader, the following situation may occur.
195 Therefore, users need to select firmware without boot loader when burning firmware.
