73 === 3.1.1 What is Dragino Bootloader? ===
74
75
76 Dragino Bootloader is a customizer made bootloader which support below features:
77
78 * OTA Update via LoRa
79 * OTA Batch update configure via LoRa
80
81 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
82
83
84 === 3.1.2 How can i know if my device already have bootloader? ===
85
86 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

89
90
91 === 3.1.3 How to upload bootloader to device? ===
92
93 If your is LoRa ST v4 base hardware and doesn't have bootloader. You can upload a bootloader to it.

98 **Update a firmware via TremoProgrammer:**
99
100 LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
101
102 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
103
104 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
105
106 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
107
108 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
109
110
111 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
112
113 1.  **TremoProgrammer** download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
114
115 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
116
117 3.  Choose software and set the address to (% style="color:blue" %)**0x08000000**(%%).
118
119 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update finish. And you should be about to see Bootloader info in output after update

125 == 3.2 Update Firmware (Assume the device already have a bootloader) ==
126
127 === 3.2.1 Update a firmware via Dragino Sensor Manager Utility.exe ===
128
129 ~1. Download **[[OTA Tool>>https://www.dropbox.com/sh/bqepfzvusv6ig8e/AACKB4J9pdY1I7s5kcKfCUGHa?dl=0]]**
130
131 2. Use below schedule to update:

142
143 == 4.1 How to recover if upgrade wrong file to bootloader? ==
144
145 You can just upload the bootloader again.
146
147
148 == 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
149
150 The UART upgrade via Dragino Sensor Manager Utility.exe is base on Dragino Bootloader. So if you are able to upgrade some file via this tool. It means the device has bootloder.
151
152
153 The upgrade via Dragino Sensor Manager Utility is base on firmware level and won't effect the bootloader. If you upgrade a wrong firmware file, you can try below:
154
155 ~1. UART upgrade via Dragino Sensor Manager Utility again to the correct version. The password should use the AT PIN for the wrong firmware.  (This method is not 100% work, depends which wrong firmware you have upgraded)
156
157 2. Use **TremoProgrammer **to update firmware. [[Insturction>>||anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
158
159 3. Use **[[OTA update>>http://wiki.dragino.com/xwiki/bin/view/Main/Firmware%20OTA%20Update%20for%20Sensors/]]**, this is base on Bootloader so it will work. Make you choose the correct frequency band (base on the firmware version in the sensor or use EU868 which is the default setting.)
160
161
162 == 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
163
164 Make sure your device already bootloader while use this update. Otherwise device won't be able to boot ( can be solve by upload a bootloader to the device).
165
166 LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
167
168 **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially.
169
170 **Step2**: Press **Reset** button, the module will then boot into program mode.
171
172 **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4.
173
174 **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software.
175
176 Below is the method for how to update via **TremoProgrammer:**
177
178 1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
179
180 2.  Run** TremoProgrammer.**
181
182 3.  Choose software and set the address to **0x0800D000**. (% class="mark" %)VERY IMPORTANT for this address(%%).
183
184 4. Rember to set BOOT Switch to **FLASH** after update
