123 === 3.1.1 What is Dragino Bootloader? ===
124
125
126 Dragino Bootloader is a customizer made bootloader which support below features:
127
128 * OTA Update via LoRa
129 * OTA Batch update configure via LoRa
130
131 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
132
133
134 === 3.1.2 How can i know if my device already have bootloader? ===
135
136
137 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

140
141
142 === 3.1.3 How to upload bootloader to device? ===
143
144
145 If your is LoRa ST v4 base hardware and doesn't have bootloader. You can upload a bootloader to it.

151
152 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:
153
154 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
155
156 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
157
158 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
159
160 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
161
162
163 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
164
165 1.  **TremoProgrammer** download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
166
167 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
168
169 3.  Choose software and set the address to (% style="color:blue" %)**0x08000000**(%%).
170
171 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

200 == 4.1 How to recover if upgrade wrong file to bootloader? ==
201
202
203 You can just upload the bootloader again.
204
205
206 == 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
207
208
209 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.
210
211
212 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:
213
214 ~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)
215
216 2. Use **TremoProgrammer **to update firmware. [[Insturction>>||anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
217
218 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.)
219
220
221 == 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
222
223
224 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).
225
226 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:

252
253 ~1. Please use lowercase letters.
254 2. You need to add line breaks when entering commands.
255 3. Upgrade the firmware to  display password firmware
256
257 Upgrade steps:

263
264 After updating the firmware, run the firmware.
265 Press the restart button and the password will be printed in the serial port output.
266 Save the password and re-upgrade the firmware to the original firmware.
267
268 (% style="color:red" %)**Note: When upgrading to the original firmware, you need to add the Bootloader firmware**.

276 == 4.5 Why does the serial Assistant print ERROR: 104/ERROR~=104 when using the AT command? ==
277
278
279 **ERROR: 104/ERROR=104** usually indicates that there is a problem when communicating with a sensor via a USB-TTL device. This error can be due to a variety of reasons, such as communication parameter setting errors, hardware connection problems, etc.
