15.3 | 55 | |
| |
13.1 | 56 | 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: |
| 57 | |||
| |
15.4 | 58 | (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially. |
| |
13.1 | 59 | |
| |
15.4 | 60 | (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode. |
| |
13.1 | 61 | |
| |
15.4 | 62 | (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4. |
| |
13.1 | 63 | |
| |
15.4 | 64 | (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software. |
| |
13.1 | 65 | |
| 66 | |||
| |
15.4 | 67 | Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:** |
| |
13.1 | 68 | |
| 69 | 1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]] | ||

| |
13.1 | 72 | |
| |
15.4 | 73 | 3. Choose software and set the address to (% style="color:blue" %)**0x0800D000** |
| |
13.1 | 74 | |
| |
15.4 | 75 | 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update |
