36.1	81	* OTA Update via LoRa
	82	* OTA Batch update configure via LoRa
24.1	83

	105	LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
	106
	107	(% style="color:blue" %)Step1(%%): Set BOOT Switch to (% style="color:blue" %)PROG(%%) mode. PROG mode is for update firmware specially.
	108
	109	(% style="color:blue" %)Step2(%%): Press (% style="color:blue" %)Reset(%%) button, the module will then boot into program mode.
	110
	111	(% style="color:blue" %)Step3(%%): Use (% style="color:blue" %)TremoProgrammer(%%) to update the firmware to LoRaST v4.
	112
	113	(% style="color:blue" %)Step4(%%): Set BOOT Switch to (% style="color:blue" %)FLASH(%%) position. Press Reset button again and module will run the new software.
	114
	115
	116	Below is the method for how to update via (% style="color:blue" %)TremoProgrammer:
	117
	118	1. TremoProgrammer download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
	119
	120	2. Run (% style="color:blue" %)TremoProgrammer.(%%)
	121
	122	3. Choose software and set the address to (% style="color:blue" %)0x08000000(%%).
	123
	124	4. Rember to set BOOT Switch to (% style="color:blue" %)FLASH(%%) after update finish. And you should be about to see Bootloader info in output after update

	152
47.6	153
42.1	154	You can just upload the bootloader again.
	155
	156
	157	== 4.2 How to recover if upgrade wrong firmware via Dragino Sensor Manager Utility.exe? ==
	158
47.6	159
42.1	160	The UART upgrade via Dragino Sensor Manager Utility.exe is base on Dragino Bootloader. So if you are able to upgrade some file via this tool. It means the device has bootloder.
	161
	162
	163	The upgrade via Dragino Sensor Manager Utility is base on firmware level and won't effect the bootloader. If you upgrade a wrong firmware file, you can try below:
	164
	165	~1. UART upgrade via Dragino Sensor Manager Utility again to the correct version. The password should use the AT PIN for the wrong firmware. (This method is not 100% work, depends which wrong firmware you have upgraded)
	166
43.1	167	2. Use TremoProgrammer to update firmware. [[Insturction>>\|\|anchor="H4.3HowtouseTremoProgrammertoupdatefirmwareifthereisbootloaderinthedevice3F"]]
42.1	168
	169	3. Use [[OTA update>>http://wiki.dragino.com/xwiki/bin/view/Main/Firmware%20OTA%20Update%20for%20Sensors/]], this is base on Bootloader so it will work. Make you choose the correct frequency band (base on the firmware version in the sensor or use EU868 which is the default setting.)

	171
	172	== 4.3 How to use TremoProgrammer to update firmware if there is bootloader in the device? ==
	173
47.6	174
42.1	175	Make sure your device already bootloader while use this update. Otherwise device won't be able to boot ( can be solve by upload a bootloader to the device).
	176
13.1	177	LoRaSTv4 Base hardware support UART update firmware. the UART connection is the same as AT Command connection, with the need for two extra action. See below for the steps:
