--=== 1.10.2 Update method: For LA66 without bootloader ===
++== 3.2  Features ==
--* Explanation:
++* LoRaWAN USB adapter base on LA66 LoRaWAN module
++* Ultra-long RF range
++* Support LoRaWAN v1.0.4 protocol
++* Support peer-to-peer protocol
++* TCXO crystal to ensure RF performance on low temperature
++* Spring RF antenna
++* Available in different frequency LoRaWAN frequency bands.
++* World-wide unique OTAA keys.
++* AT Command via UART-TTL interface
++* Firmware upgradable via UART interface
++* Open Source Mobile App for LoRaWAN signal detect and GPS tracking.
--For LA66 without a bootloader, we can only burn a bootloader for it in the following way. Because using OTA_Tool to upgrade the firmware of LA66 this address is (% style="color:blue" %)**0x0800D000**(%%) by default, but our bootloader needs to be burned at address .
