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