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.

148
149 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
150
151
152 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.
153
154 (% style="color:red" %)**Here are notice:**
155
156 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
157
158 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
173 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.

198 == 4.6 The old version LA66 is different from the new version LA66. Can OTA_Tool be used for both versions? ==
199
200
201 The most obvious hardware difference between LA66 V1 and LA66v2 when burning is the presence of a "RESET "button, and the RESET operation is only for LA66 without a boot loader, you can refer to this link to learn how to upgrade LA66 without a boot loader：[[LA66 USB LoRaWAN Adapter User Manual - DRAGINO>>url:https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]]
202
203 [[image:image-20250122134752-6.png||height="288" width="543"]]
204
205 In summary, as long as your LA66 has a boot loader, either LA66 V1 or LA66 V2 can use OTA_Tool.
206
207
208 == 4.7 Why can't LA66 burn its own working firmware after it is used for OTA upgrade of -LB products? ==
209
210
211 We are sorry for the inadequacy of LA66 for OTA updates in the past.
212
213 * In the past, the download address of LA66 OTA DONGLE V1.0 was (% style="color:blue" %)**0x08000000**(%%), and the address of the bootloader that existed by default when the LA66 was shipped was also (% style="color:blue" %)**0x08000000**(%%).
214
215 Therefore, when you burn OTA_Firmwar v1.0 (LA66 OTA DONGLE v1.0) for the LA66 in order to use the LA66‘s ability to perform OTA upgrades for -LB products, the LA66’s bootloader is overridden.
216
217 So if you need to switch back to the LA66's working firmware, you'll need to refer to this [[link>>https://wiki.dragino.com/xwiki/bin/view/Main/User%20Manual%20for%20LoRaWAN%20End%20Nodes/LA66%20USB%20LoRaWAN%20Adapter%20User%20Manual/#H1.10.2Updatemethod:A0ForLA66withoutbootloader]] for instructions to burn firmware with a bootloader for the LA66.
218
219 [[image:image-20250122113225-5.png||height="336" width="798"]]
220
221 * For the new version of LA66 OTA DONGLE V1.1, we have changed the supported download address to (% style="color:blue" %)**0x0800D000**(%%) the same as other working firmware addresses, so you can simply use OTA_Tool to burn LA66 OTA DONGLE V1.1 and LA66 working firmware for LA66.
