| 29 | ~1. Use a general serial tool. | ||
| 30 | |||
| 31 | 2. Connect PC to device's UART interface | ||
| 32 | |||
| 33 | 3. Set up serial tool with : BaudRate: 9600, databit:8, No parity, No flow control. | ||

| 66 | === 3.1.1 What is Dragino Bootloader? === | ||
| 67 | |||
| 68 | |||
| 69 | Dragino Bootloader is a customizer made bootloader which support below features: | ||
| 70 | |||
| 71 | * OTA Update via LoRa or BLE | ||
| 72 | * OTA Batch update configure via LoRa or BLE | ||

| 83 | === 3.1.2 How can i know if my device already have bootloader? === | ||
| 84 | |||
| 85 | If a device has a bootloader. it will output bootloader info to UART when boot. As below: | ||

| 90 | === 3.1.3 How to upload bootloader to device? === | ||
| 91 | |||
| 92 | |||
| 93 | |||
| 94 | == 3.2 Update Firmware (Assume the device already have a bootloader) == | ||
| 95 | |||
| 96 | === 3.2.1 Update a firmware via Dragino bootloader === | ||
| 97 | |||
| 98 | |||
| 99 | |||
| 100 | |||
| 101 | === 3.2.2 Update a firmware via TremoProgrammer === | ||
| 102 | |||
| 103 | Make sure your device already bootloader while use this update. Other device won't be able to boot ( can be solve by upload a bootloader to the device). | ||
| 104 | |||
| 105 | 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: | ||
| 106 | |||
| 107 | (% style="color:blue" %)**Step1**(%%): Set BOOT Switch to (% style="color:blue" %)**PROG**(%%) mode. PROG mode is for update firmware specially. | ||
| 108 | |||
| 109 | (% style="color:blue" %)**Step2**(%%): Press (% style="color:blue" %)**Reset**(%%) button, the module will then boot into program mode. | ||
| 110 | |||
| 111 | (% style="color:blue" %)**Step3**(%%): Use (% style="color:blue" %)**TremoProgrammer**(%%) to update the firmware to LoRaST v4. | ||
| 112 | |||
| 113 | (% style="color:blue" %)**Step4**(%%): Set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) position. Press Reset button again and module will run the new software. | ||
| 114 | |||
| 115 | |||
| 116 | Below is the method for how to update via (% style="color:blue" %)**TremoProgrammer:** | ||
| 117 | |||
| 118 | 1. Software download link: [[https:~~/~~/www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0>>url:https://www.dropbox.com/sh/j0qyc7a9ejit7jk/AACtx2tK4gEv6YFXMIVUM4dLa?dl=0]] | ||
| 119 | |||
| 120 | 2. Run** (% style="color:blue" %)TremoProgrammer.(%%)** | ||
| 121 | |||
| 122 | 3. Choose software and set the address to (% style="color:blue" %)**0x0800D000**(%%). (% style="color:red" %)VERY IMPORTANT: USE THIS ADDRESS FOR FIRMWARE WITHOUT BOOTLOADER | ||
| 123 | |||
| 124 | 4. Rember to set BOOT Switch to (% style="color:blue" %)**FLASH**(%%) after update | ||
