47 User can find the firmware in the [[**NB-IoT Product Share directory**>>https://www.dropbox.com/sh/qasyy7n8631lve2/AABZFontYtyj6Meyxd7Tar7Ta?dl=0]]: There are two kind of firmware:
48
49 * **.bin** : original firmware file.
50 * **.hex** : file with control / meta info.
51
52 (% class="wikigeneratedid" %)
53 Please note that user needs to use (% class="mark" %)**.bin**(%%) file for update.

61
62 Below is the example BLE to USB TTL adapter. Insert it to PC

65
66
67 (% class="lead" %)
68 (% style="color:blue" %)**Step2:**(%%)**  Modify Bluetooth host parameters to support Dragino Sensor Management Tool** **v1.4**
69
70 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.
71
72 If your Bluetooth host's baud rate is already 115200, please refer to (% style="color:blue" %)**Step3**(%%) directly.
73
74 * 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.
75
76 An example diagram is as follows:

79
80 (% style="color:red" %)**Note:**
81
82 (% 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.**
83
84 (% 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.**
85
86 * If the serial command sending fails, please modify the sending settings of the serial assistant as below:

99
100 (% 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).**
101
102 * Select the** **Dragino Sensor Management Tool parameter:

105
106 * Before clicking "Start", make sure that the switch of the node is in **FLASH**.

109
110
111 * 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.

117 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.**
118 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.**
119 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.**

147
148 **How to operate:**
149
150 1. After the upgrade is interrupted, you need to close the wireless upgrade tool and reopen it later.
151
152 2. Before restarting the upgrade, you need to reset the Bluetooth host, otherwise the upgrade may not be possible.
153
154 * If your Bluetooth host has a RESET button, you can use the RESET button to reset it.
155 * 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.
