20 (% style="color:blue" %)**LA66 USB LoRaWAN Adapter**(%%) is designed to fast turn USB devices to support LoRaWAN wireless features. It combines a CP2101 USB TTL Chip and LA66 LoRaWAN module which can easy to add LoRaWAN wireless feature to PC / Mobile phone or an embedded device that has USB Interface.

24 (% style="color:blue" %)**LA66**(%%) is a ready-to-use module that includes the (% style="color:blue" %)**LoRaWAN v1.0.3 protocol**(%%). The LoRaWAN stack used in LA66 is used in more than 1 million LoRaWAN End Devices deployed world widely. This mature LoRaWAN stack greatly reduces the risk to make stable LoRaWAN Sensors to support different LoRaWAN servers and different countries' standards. External MCU can use AT command to call LA66 and start to transmit data via the LoRaWAN protocol.

344 == 1.10  Upgrade Firmware of LA66 USB LoRaWAN Adapter ==
345
346
347 === 1.10.1 Update method: For LA66 with bootloader ===
348
349
350 * We ship the LA66 USB LoRaWAN Adapter with a boot loader by default, and the latest boot loader is V1.4. Users can download the new version of the boot loader by clicking on this [[link>>https://www.dropbox.com/scl/fo/ztlw35a9xbkomu71u31im/AFhmjtEOaipfBAFrpMCoWrI/LoRaWAN%20End%20Node/LA66%20LoRaWAN%20module/Firmware/OTA_Firmware?dl=0&rlkey=ojjcsw927eaow01dgooldq3nu&subfolder_nav_tracking=1]].

353
354 (% style="color:red" %)**Note: Upgrading the boot loader requires using the upgrade method described in section 1.10.2.**
355
356
357 * For the bootloader V1.4, compared to V1.3, his role is to support OTA configuration for T68DL (D let Gino product model).
358
359 So if your LA66 doesn't need this feature, you can also just follow the below to upgrade the firmware instead of the bootloader:

371
372
373 === 1.10.2 Update method: For LA66 without bootloader ===
374
375
376 * Explanation:
377
378 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 .
379
380 Therefore, you can use this method to download the firmware with the boot loader directly or upgrade your boot loader (address from (% style="color:blue" %)**0x08000000**(%%)).

388
389 * Upgrade Details:
390
391 The LA66 USB LoRaWAN Adapter is the same as the LA66 LoRaWAN Shield update method.
392
393 Just use the yellow jumper cap to short the BOOT corner and the RX corner, and then press the RESET button (without the jumper cap, you can directly short the BOOT corner and the RX corner with a wire to achieve the same effect).
394
395 (% style="color:red" %)**Notice: If upgrade via USB hub is not sucessful. try to connect to PC directly.**
396
397 [[image:image-20220723150132-2.png||height="514" width="506"]]
398
399
400 (% style="color:blue" %)**For the LA66 USB LoRaWAN Adapter v1.2, the hardware design has eliminated the reset button, so the first step we need to use the DuPont wire to connect the BOOT pin to the RX pin. Second, connect the LA66 USB LoRaWAN Adapter v1.2 to a USB hub or computer USB port so that it will enter burn mode. Then follow the steps below to burn the firmware.**
401
402 (% style="color:red" %)**Note: After the successful burning need to unplug the LA66 USB LoRaWAN Adapter v1.2, and then reconnect the computer interface, so that it will exit the burning mode.**
