150
151 Dragino Bootloader is a customizer made bootloader which support below features:
152
153 * OTA Update via LoRa
154 * OTA Batch update configure via LoRa
155
156 All Dragino End Devices base on LoRa ST v4 supports Dragino Bootloader.
157
158
159 === 3.1.2 How can i know if my device already have bootloader? ===
160
161
162 If a device has a bootloader. it will output bootloader info to UART when boot. As below:

230
231 == 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
232
233
234 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.
235
236
237 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:
238
239 ~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)
240
241 2. Use **TremoProgrammer **to update firmware. [[Insturction>>||anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
242
243 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.)
244
245
246 == 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
247
248
249 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).

302
303
304 **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.
