13.1 | 40 | == General Instruction for UART update firmware == |
| 41 | |||
| 42 | 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: | ||
| 43 | |||
| 44 | **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially. | ||
| 45 | |||
| 46 | **Step2**: Press **Reset** button, the module will then boot into program mode. | ||
| 47 | |||
| 48 | **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4. | ||
| 49 | |||
| 50 | **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software. | ||
| 51 | |||
| 52 | |||
| 53 | Below is the method for how to update via **TremoProgrammer:** | ||
| 54 | |||
| 55 | 1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]] | ||

| 59 | 3. Choose software and set the address to **0x0800D000** | ||
| 60 | |||
| 61 | 4. Rember to set BOOT Switch to FLASH after update | ||
