64 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:
65
66 (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially.
67
68 (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode.
69
70 (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4.
71
72 (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software.
73
74
75 Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:**
76
77 1.  Software download link:  [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]]
78
79 2.  Run** (% style="color:blue" %)TremoProgrammer.(%%)**
80
81 3.  Choose software and set the address to (% style="color:blue" %)**0x0800D000(%%)**. (% style="color:red" %)VERY IMPORTANT: USE THIS ADDRESS FOR FIRMWARE WITHOUT BOOTLOADER(%%)
82
83 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update
