26.24	74
24.1	75	Dragino Bootloader is a customizer made bootloader which support below features:
	76
	77	* OTA Update via LoRa or BLE
	78	* OTA Batch update configure via LoRa or BLE
	79
	80
	81
28.1	82	=== 3.1.2 How can i know if my device already have bootloader? ===
26.26	83
28.1	84	If a device has a bootloader. it will output bootloader info to UART when boot. As below:

	98
	99
	100	=== 3.2.2 Update a firmware via TremoProgrammer ===
	101
	102	Make sure your device already bootloader while use this update. Other device won't be able to boot ( can be solve by upload a bootloader to the device).

13.1	104	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:
	105
15.4	106	(% style="color:blue" %)Step1(%%): Set BOOT Switch to (% style="color:blue" %)PROG(%%) mode. PROG mode is for update firmware specially.
13.1	107
15.4	108	(% style="color:blue" %)Step2(%%): Press (% style="color:blue" %)Reset(%%) button, the module will then boot into program mode.
13.1	109
15.4	110	(% style="color:blue" %)Step3(%%): Use (% style="color:blue" %)TremoProgrammer(%%) to update the firmware to LoRaST v4.
13.1	111
15.4	112	(% style="color:blue" %)Step4(%%): Set BOOT Switch to (% style="color:blue" %)FLASH(%%) position. Press Reset button again and module will run the new software.
13.1	113
	114
15.4	115	Below is the method for how to update via (% style="color:blue" %)TremoProgrammer:
13.1	116
	117	1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
	118
15.4	119	2. Run (% style="color:blue" %)TremoProgrammer.(%%)
13.1	120
23.1	121	3. Choose software and set the address to (% style="color:blue" %)0x0800D000(%%). (% style="color:red" %)VERY IMPORTANT: USE THIS ADDRESS FOR FIRMWARE WITHOUT BOOTLOADER
13.1	122
15.4	123	4. Rember to set BOOT Switch to (% style="color:blue" %)FLASH(%%) after update
