	41	+
	42	+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:
	43	+
	44	+ **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially.
	45	+
	46	+ **Step2**: Press **Reset** button, the module will then boot into program mode.
	47	+
	48	+ **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4.
	49	+
	50	+ **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software.
	51	+
	52	+
	53	+Below is the method for how to update via **TremoProgrammer:**
	54	+
	55	+1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
	56	+
	57	+2.  Run** TremoProgrammer.**
	58	+
	59	+3.  Choose software and set the address to **0x0800D000**
	60	+
	61	+4. Rember to set BOOT Switch to FLASH after update
