81 +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.

95 +== 4.1 Can i use other devices to connect to PC if i don't have LA66 USB? ==
96 +
97 +If user doesn't have LA66 USB Adapter, they can still use other Dragino Device to connect to PC for OTA update. Steps:
98 +
99 +* Find the suitable mode which base on LA66 chip ( All LoRaWAN model with LB or LS suffix , such as SN50v3-LB)
100 +* Update the LA66 USB OTA firmware to the device.
101 +* Connect the device to PC via UART interface.
102 +* 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.
