146 === 3.1.1 What is Dragino Bootloader? ===
147
148
149 Dragino Bootloader is a customizer made bootloader which support below features:
150
151 * OTA Update via LoRa
152 * OTA Batch update configure via LoRa
153
154 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
155
156
157 === 3.1.2 How can i know if my device already have bootloader? ===
158
159
160 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

226 You can just upload the bootloader again.
227
228
229 == 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
230
231
232 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.
233
234
235 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:
236
237 ~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)
238
239 2. Use **TremoProgrammer **to update firmware. [[Insturction>>||anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
240
241 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.)
242
243
244 == 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
245
246
247 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).

299 == 4.5 Why does the serial Assistant print ERROR: 104/ERROR~=104 when using the AT command? ==
300
301
302 **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.
