| 53 | |||
| 54 | |||
| 55 | 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: | ||
| 56 | |||
| 57 | (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially. | ||
| 58 | |||
| 59 | (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode. | ||
| 60 | |||
| 61 | (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4. | ||
| 62 | |||
| 63 | (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software. | ||
| 64 | |||
| 65 | |||
| 66 | Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:** | ||
| 67 | |||
| 68 | 1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]] | ||
| 69 | |||
| 70 | 2. Run** (% style="color:blue" %)TremoProgrammer.(%%)** | ||
| 71 | |||
| 72 | 3. Choose software and set the address to (% style="color:blue" %)**0x0800D000** | ||
| 73 | |||
| 74 | 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update | ||

| 81 | |||
| 82 | Below shows the SIB board UART connection, reset button and BOOT Switch (Program Jumper) position. They can be used for firmware upgrade reference. | ||
