Edwin Chen 7.1 77
Xiaoling 10.2 78
Edwin Chen 7.1 79 After press reset button, LA66 USB will restart and broadcast update process with the Dev EUI and Password.

Edwin Chen 7.1 83
Xiaoling 10.2 84
Edwin Chen 7.1 85 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.

Edwin Chen 14.1 96 = 4. FAQ =
Edwin Chen 7.1 97
Edwin Chen 14.1 98 == 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
99
100
Xiaoling 20.2 101 If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update.
102
103 (% style="color:blue" %)**Steps:**
104
Edwin Chen 14.1 105 * Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
Xiaoling 20.2 106
Edwin Chen 14.1 107 * Update the LA66 USB OTA firmware to the device.
Xiaoling 20.2 108
Edwin Chen 14.1 109 * Connect the device to PC via UART interface.
Xiaoling 20.2 110
Edwin Chen 14.1 111 * 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.

Edwin Chen 19.1 115 == 4.2 Where to find OTA Password? ==
116
Xiaoling 20.2 117
Edwin Chen 19.1 118 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.

Edwin Chen 20.1 123 == 4.3 How about if i upgrade a crashed firmware via OTA update? ==
Edwin Chen 19.1 124
Edwin Chen 20.1 125
Xiaoling 20.2 126 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.
Edwin Chen 20.1 127
Xiaoling 20.2 128 (% style="color:red" %)**Here are notice:**
Edwin Chen 20.1 129
Xiaoling 20.2 130 ~1. OTA update frequency depend on the firmware frequency. If there is no frequency in the firmware. Bootloader will use EU868 as default frequency.
Edwin Chen 20.1 131
Xiaoling 20.2 132 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.
