13.1	63	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:
	64
15.4	65	(% style="color:blue" %)Step1(%%): Set BOOT Switch to (% style="color:blue" %)PROG(%%) mode. PROG mode is for update firmware specially.
13.1	66
15.4	67	(% style="color:blue" %)Step2(%%): Press (% style="color:blue" %)Reset(%%) button, the module will then boot into program mode.
13.1	68
15.4	69	(% style="color:blue" %)Step3(%%): Use (% style="color:blue" %)TremoProgrammer(%%) to update the firmware to LoRaST v4.
13.1	70
15.4	71	(% 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	72
	73
15.4	74	Below is the method for how to update via (% style="color:blue" %)TremoProgrammer:
13.1	75
	76	1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
	77
15.4	78	2. Run (% style="color:blue" %)TremoProgrammer.(%%)
13.1	79
15.4	80	3. Choose software and set the address to (% style="color:blue" %)0x0800D000
13.1	81
15.4	82	4. Rember to set BOOT Switch to (% style="color:blue" %)FLASH(%%) after update
