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.

103
104
105 === (% style="color:blue" %)**Step3:**(%%) Press Start in OTA Tool and then Press Reset button to restart LA66 USB ===
106
107
108 After press reset button, LA66 USB will restart and broadcast update process with the Dev EUI and Password.
109
110
111 === (% style="color:blue" %)**Step4:** (%%)Press reset button on the end node, or re-activate the end node. ===
112
113
114 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.
115
116
117 === (% style="color:blue" %)**Step5:**(%%) Check result. ===

133 = 4. FAQ =
134
135 == 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
136
137
138 If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
139
140 (% style="color:blue" %)**Steps:**
141
142 * Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
143
144 * Update the LA66 USB OTA firmware to the device.
145
146 * Connect the device to PC via UART interface.
147
148 * 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.
149
150 == 4.2 Where to find OTA Password? ==
151
152
153 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.

156
157
158 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
159
160
161 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.
162
163 (% style="color:red" %)**Here are notice:**
164
165 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
166
167 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.
168
169
170 == 4.4 Will OTA update effect the Local LoRaWAN Network. ==
171
172 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.
173
174 (% class="mark" %)#Define the OTA frequency use for OTA.
175 #End Node has FRE1 and SF=5. So don't change FRE1 settings
176 #FRE2 include several frequencies point.
177 #PC first use FRE1 to create connection to end node, then use one of FRE2 frequencies to process downlink.
