Edwin Chen 22.1 49 * **.bin** : original firmware file.
50 * **.hex** : file with control / meta info.

Mengting Qiu 45.1 68 (% style="color:blue" %)**Step2:**(%%)**  Modify Bluetooth host parameters to support Dragino Sensor Management Tool** **v1.4**
Ellie Zhang 2.1 69
Mengting Qiu 45.1 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.
kai 32.2 71
Mengting Qiu 45.1 72 If your Bluetooth host's baud rate is already 115200, please refer to (% style="color:blue" %)**Step3**(%%) directly.
kai 32.2 73
Mengting Qiu 45.1 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.
kai 34.2 75
Mengting Qiu 45.1 76 An example diagram is as follows:

Mengting Qiu 45.1 80 (% style="color:red" %)**Note:**
kai 33.1 81
Mengting Qiu 46.1 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.**
kai 34.2 83
Mengting Qiu 45.1 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.**
kai 34.2 85
Mengting Qiu 45.1 86 * If the serial command sending fails, please modify the sending settings of the serial assistant as below:

Mengting Qiu 56.1 148 **How to operate:**
Mengting Qiu 55.1 149
kai 42.1 150 1. After the upgrade is interrupted, you need to close the wireless upgrade tool and reopen it later.
151
kai 43.1 152 2. Before restarting the upgrade, you need to reset the Bluetooth host, otherwise the upgrade may not be possible.
kai 42.1 153
Mengting Qiu 56.1 154 * If your Bluetooth host has a RESET button, you can use the RESET button to reset it.
Mengting Qiu 57.1 155 * 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.
