47 +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:
48 +
49 + (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
50 +
51 + (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
52 +
53 + (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
54 +
55 + (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
56 +
57 +
58 +Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
59 +
60 +1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
61 +
62 +2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
63 +
64 +3.  Choose software and set the address to (% style="color:blue" %)**0x0800D000**
65 +
66 +4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update
