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.

101
102 === (% style="color:blue" %)**Step3:**(%%) Press Start in OTA Tool and then Press Reset button to restart LA66 USB ===
103
104
105 After press reset button, LA66 USB will restart and broadcast update process with the Dev EUI and Password.
106
107
108 === (% style="color:blue" %)**Step4:** (%%)Press reset button on the end node, or re-activate the end node. ===
109
110
111 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.
112
113
114 === (% style="color:blue" %)**Step5:**(%%) Check result. ===

127 OTA Update Configure is good for batch update configure in same type of sensors.

130 = 4. FAQ =
131
132 == 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
133
134
135 If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
136
137 (% style="color:blue" %)**Steps:**
138
139 * Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
140
141 * Update the LA66 USB OTA firmware to the device.
142
143 * Connect the device to PC via UART interface.
144
145 * 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.
146
147 == 4.2 Where to find OTA Password? ==
148
149
150 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.

153
154
155 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
156
157
158 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.
159
160 (% style="color:red" %)**Here are notice:**
161
162 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
163
164 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.
165
166
167 = 5. OTA Tool Known Bug: =
168
169
170 ~1. If user click "(% style="color:blue" %)**Start**"(%%) but there is issue during update. User may need to close and open the tool again.
