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]]
