| 30 | == General Instruction for UART update firmware == | ||
| 31 | |||
| 32 | 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: | ||
| 33 | |||
| 34 | **Step1**: Set BOOT Switch to **PROG** mode. PROG mode is for update firmware specially. | ||
| 35 | |||
| 36 | **Step2**: Press **Reset** button, the module will then boot into program mode. | ||
| 37 | |||
| 38 | **Step3**: Use **TremoProgrammer** to update the firmware to LoRaST v4. | ||
| 39 | |||
| 40 | **Step4**: Set BOOT Switch to **FLASH** position. Press Reset button again and module will run the new software. | ||
| 41 | |||
| 42 | |||
| 43 | Below is the method for how to update via **TremoProgrammer:** | ||
| 44 | |||
| 45 | 1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]] | ||
| 46 | |||
| 47 | 2. Run** TremoProgrammer.** | ||
| 48 | |||
| 49 | 3. Choose software and set the address to **0x0800D000** | ||
| 50 | |||
| 51 | 4. Rember to set BOOT Switch to FLASH after update | ||
