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.

105
106
107 Upon re-plugging, the LA66 USB will reboot and broadcast the update process using the Dev EUI and passcode

109
110 === (% style="color:blue" %)**Step4:** (%%)Press reset button on the end node, or re-activate the end node. ===
111
112 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.
113
114 [[image:image-20250121093705-3.png]]
115
116 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.

127 = 4. FAQ =
128
129 == 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
130
131
132 If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
133
134 (% style="color:blue" %)**Steps:**
135
136 * Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
137
138 * Update the LA66 USB OTA firmware to the device.
139
140 * Connect the device to PC via UART interface.
141
142 * 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.
143
144 == 4.2 Where to find OTA Password? ==
145
146
147 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.

150
151
152 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
153
154
155 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.
156
157 (% style="color:red" %)**Here are notice:**
158
159 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
160
161 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.

172 == 4.5 Will OTA update effect the Local LoRaWAN Network. ==
173
174 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.
175
176 (% class="mark" %)#Define the OTA frequency use for OTA.
177 #End Node has FRE1 and SF=5. So don't change FRE1 settings
178 #FRE2 include several frequencies point.
