10 There are some new models of Dragino sensors support OTA update via Private LoRa Protocol, (Even the sensor runs LoRaWAN protocol by default).
11
12 User can use the OTA update to update the configure file or firmware to the sensors.

112
113 When the OTA Tool displays “**LA66 is scanning for sensor Dev EUI ‘(% style="color:blue" %)DevEUI(%%)’. Please reset the sensor for connection and update**”, press and hold the ACT button on the terminal node for 5 seconds to perform a terminal node reset so that the OTA Tool can connect successfully.
114
115 [[image:image-20250121093705-3.png]]
116
117 In every reboot/ reactivate, the end node will check if there is update request. If end node gets the update request from LA66. End node will check if the Dev EUI and Password match. If match, End node will establish connection with LA66 USB for OTA update.

136 = 4. FAQ =
137
138 == 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
139
140
141 If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
142
143 (% style="color:blue" %)**Steps:**
144
145 * Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
146
147 * Update the LA66 USB OTA firmware to the device.
148
149 * Connect the device to PC via UART interface.
150
151 * Make sure power off or update the firmware back to original firmware , because the LA66 USB OTA fimware is not low power consumption firmware. it will consume the battery very fast.
152
153 == 4.2 Where to find OTA Password? ==
154
155
156 Each device has a shipped label with OTA Password which is 16 chars. like below. If user don't find this, please send us a photo for the device with Dev EUI to [[support@dragino.com>>mailto:support@dragino.com]] . and we will search the password for you.

159
160
161 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
162
163
164 OTA update is done via Bootloader and only change the firmware partition. So update a crash firmware via OTA update won't destroy bootloader and user can use OTA method to update again.
165
166 (% style="color:red" %)**Here are notice:**
167
168 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
169
170 2. OTA update require a reset or reactivate action. If the crash firmware doesn't have them work, user need to manuall push the physic reset button on the PCB or power off/on device.

181 == 4.5 Will OTA update effect the Local LoRaWAN Network. ==
182
183 User can configure the OTA_Frequency.txt file to change the Update frequency point so it won't conflict with the general LoRa Frequency. See below for the file as reference and explain. The OTA update also use a none-use SF (SF=5) which won't conflict with the current use SF.
184
185 (% class="mark" %)#Define the OTA frequency use for OTA.
186 #End Node has FRE1 and SF=5. So don't change FRE1 settings
187 #FRE2 include several frequencies point.
