【RW007系列综合实战3】柿饼派上怎样更新RW007固件和驱动？
前面已經(jīng)分享過部分關(guān)于 RW007 模塊如何更新的帶 BLE 功能的方法，這里也再次分享一下在柿餅派上怎樣更新 RW007 固件和更新 RW007 的驅(qū)動，并且測試 RW007 的 BLE 功能。
步驟一：柿餅派更新 RW007 的固件
在柿餅派上更新 RW007 的固件，可以參考官方提供的 RW007 通過 UDP_OTA 工具升級 RW007 固件的文檔，進(jìn)行操作。
1. RW007 模塊需要和 PC 電腦連在同一個局域網(wǎng)
2. 打開升級工具配置升級
（1）雙擊運(yùn)行 udp_ota.exe軟件
3. 升級完成
等待進(jìn)度條完成，然后重啟板子。
步驟二：柿餅派修改 SDK 更新 RW007 的驅(qū)動
由于需要使用新版本的 RW007 模塊的 BLE 功能，所以需要對應(yīng)更新主機(jī)端柿餅派的 RW007 驅(qū)動，主要是替換SDK中project\firmware\packages目錄下的rw007-latest目錄先刪除，然后拷貝提供的rw007-v2.0.1文件夾，即可完成替換更新RW007 的驅(qū)動。
替換驅(qū)動文件后，通過 env 編譯柿餅派的固件，然后通過persimmon mod工具更新柿餅派的固件，即可。
步驟三：柿餅派測試 RW007 的 BLE 功能
當(dāng)按照前面的步驟進(jìn)行操作后，可以通過調(diào)試串口的 msh命令行進(jìn)行調(diào)試。因?yàn)樵赗W007驅(qū)動包里面默認(rèn)開啟了相關(guān)的功能測試示例，可以在MSH命令行中通過rw007_ble查詢。下面的內(nèi)容來自于官方提供的 RW007 BLE 功能使用說明操作。

1msh?/>rw007_ble?init?central 2122?-?ble_cmd_init 3start?ble?central 4msh?/>2. RW007BLE 設(shè)備初始化為從機(jī)設(shè)備
注意：目前不支持使用從機(jī)模式。
BLE 功能獲取本機(jī)的BLE設(shè)備地址
由于BLE設(shè)備的地址分為public公共地址和random隨機(jī)地址。
1rw007_ble?get_addr測試示例
1msh?/>rw007_ble?get_addr 2273?-?ble_cmd_get_addr 3msh?/>resp_type:?0,?len:?12 4RW007_BLE_RSP_TYPE_ADDR_GET 5public_id_addr?=?48:00:42:8c:47:c9 6random_id_addr?=?00:04:5c:43:00:00BLE 功能掃描設(shè)備
目前RW007BLE 功能支持通過 scan命令，掃描周圍的BLE設(shè)備。
1.執(zhí)行掃描周圍BLE設(shè)備
1rw007_ble?scan測試示例：
1msh?/>rw007_ble?scan 2176?-?ble_cmd_scan 3msh?/>resp_type:?1,?len:?65 4RW007_BLE_NTF_TYPE_DISCOVER 5received?advertisement;?event_type=0?rssi=-60?addr_type=0?addr=4c:ed:fb:00:04:b1 6resp_type:?1,?len:?56這里的 addr地址內(nèi)容可以為后面連接設(shè)備使用，由于目前沒有直接顯示對應(yīng) BLE 設(shè)備的名稱，需要先人工確定 BLE 設(shè)備的地址。
2.停止掃描周圍BLE設(shè)備
該指令用于 RW007模塊正在執(zhí)行scan掃描操作過程中，馬上停止掃描的動作，可以執(zhí)行此命令。
BLE 功能設(shè)備連接
目前 RW007 BLE 功能設(shè)備支持通過 BLE設(shè)備的類mac地址來連接設(shè)備,該命令僅支持主機(jī)模式去連接從機(jī)設(shè)備的類mac地址,連接成功后會有對應(yīng)的conn_handle值，這個conn_handle值在其他功能沿用。
1rw007_ble?connect?xx:xx:xx:xx:xx:xx測試示例
1msh?/>rw007_ble?connect?4c:ed:fb:00:04:b12198?-?ble_cmd_connect3str_addr:?4c:ed:fb:00:04:b14mac?addr:?b1:?4:?0:fb:ed:4c5msh?/>resp_type:?1,?len:?526RW007_BLE_NTF_TYPE_CONNECT7type:?0,?status:?0,?conn_handle:?189resp_type:?1,?len:?44 10RW007_BLE_NTF_TYPE_CONNECT_DESC 11our_id_addr:?c9:47:8c:42:00:48 12peer_id_addr:?b1:04:00:fb:ed:4cBLE 功能設(shè)備斷開連接
目前RW007BLE 功能設(shè)備支持主動斷開從設(shè)備的連接。

測試示例中的 [conn_handle]為 1，[UUID]為ebe0ccbe7a0a4b0c8a1a6ff2997da3a6,[data]為 0x00(這里是使用 hex 值)
BLE 功能更新notify 參數(shù)
目前 RW007 BLE 功能支持修改接收 notify參數(shù)。
1rw007_ble?notify_change?[conn_handle]?[char_value]?[UUID]參數(shù)說明：
[conn_handle]為 RW007連接設(shè)備時生成的對應(yīng)值
[char_value] 為配置參數(shù)，具體如下
10：disable?indication¬ification 21：enable?notification，disable?indication 32：enable?indication，?disable?notification 43：enable?indication?¬ification[UUID]為對應(yīng) BLE設(shè)備的特征參數(shù)值。
BLE 功能關(guān)于廣播包類型的說明
目前 RW007 ?BLE 功能中可以關(guān)于廣播包 event的類型可以分為下面幾種。

步驟四：柿餅派讀取米家藍(lán)牙溫濕度計數(shù)據(jù)顯示在界面上
感謝能堅持看到這里的每一個你，下面將會通過添加編寫部分功能代碼和創(chuàng)建 UI 工程，實(shí)現(xiàn)柿餅派讀取米家溫濕度計數(shù)據(jù)顯示在界面上的功能。接下來會貼一部分實(shí)現(xiàn)代碼和代碼說明，可能會有點(diǎn)乏味，但是盡可能把實(shí)現(xiàn)步驟描述得具體些，避免采坑。
1. 添加測試文件，參考代碼
2. 編譯固件，驗(yàn)證功能
3. 創(chuàng)建 UI 工程，簡單布局
4. c-js 之間互通說明
5. UI 工程修改，驗(yàn)證功能
1.添加測試代碼
在官方提供的 SDK中的project\firmware\applications目錄下添加ble_example.c文件，然后參考project\firmware\packages\rw007-v2.0.1\src\ble_cmd_rw007.c文件，主要拷貝幾個對應(yīng)的函數(shù)。通過前面的可以了解到，需要（1）RW007 初始化為 BLE 主機(jī)模式 （2）RW007 連接米家藍(lán)牙溫濕度計2代設(shè)備 （3）RW007 通過 UUID 讀取米家藍(lán)牙溫濕度計2代設(shè)備的數(shù)據(jù) ，所以需要參考 BLE功能初始化、連接、通過 UUID 讀取數(shù)據(jù)的功能實(shí)現(xiàn)函數(shù)。
（1）在ble_example.c中添加 RW007 初始化為BLE主機(jī)模式的函數(shù)
1static?int?ble_example_init(void)2{3????rt_kprintf("ble_example_init\n");4????rt_uint8_t?roles?=?0;5????roles?=?RW007_BLE_INIT_ROLE_CENTRAL;67????rw007_ble_init(roles);89????rw007_ble_resp_handle_cb_reg(rw007_ble_resp_handle); 10????rw007_ble_ntf_handle_cb_reg(rw007_ble_ntf_handle); 11????return?0; 12 13}由于在初始化函數(shù)中，需要注冊兩個回調(diào)函數(shù)rw007_ble_resp_handle 和 rw007_ble_ntf_handle,所以也要從project\firmware\packages\rw007-v2.0.1\src\ble_cmd_rw007.c文件中對應(yīng)拷貝過來。

（3）RW007 通過 UUID 讀取米家藍(lán)牙溫濕度計2代設(shè)備的數(shù)據(jù)
?由于前面通過 BLE 測試連接上米家藍(lán)牙溫濕度計2代設(shè)備后，會主動收到來自米家藍(lán)牙溫濕度計2代設(shè)備的溫濕度數(shù)據(jù)的notify,并在rw007_ble_ntf_handle函數(shù)中打印輸出，現(xiàn)在需要解析接收到的溫濕度數(shù)據(jù)，在rw007_ble_ntf_handle的函數(shù)中添加解析數(shù)據(jù)的功能。
c case RW007_BLE_NTF_TYPE_NOTIFY_RX: { struct rw007_ble_gap_event_notify_rx *notify_rx; char cRes[50] = {0}; ¨K60K
(4) 添加通過命令啟動函數(shù)，測試功能
1static?int?ble_example_start(void)2{3????ble_example_init();4????rt_thread_delay(1000);5????ble_example_connect();6????rt_thread_delay(5000);7????return?0;89} 10MSH_CMD_EXPORT(ble_example_start,ble_example_start)說明：這里加了一些延時是考慮到連接設(shè)備需要一些時間。
(5)編譯固件，燒錄驗(yàn)證功能
編譯固件，給柿餅派升級固件后，通過在調(diào)試串口 msh中輸入ble_example_start命令進(jìn)行啟動，啟動后便會連接米家藍(lán)牙溫濕度計2代設(shè)備，并把獲取到溫濕度數(shù)據(jù)進(jìn)行解析，打印出來。
添加把數(shù)據(jù)傳遞到界面的實(shí)現(xiàn)函數(shù)（C-To-JS）
通過前面的步驟，已經(jīng)成功解析到了米家藍(lán)牙溫濕度計2代設(shè)備的溫濕度數(shù)據(jù)，現(xiàn)在需要把這些數(shù)據(jù)顯示到 LCD 屏上，需要在 SDK 中參考示例代碼中的docs\src\PersimM3_JS_GUI_C_TransData\js_message_test.c進(jìn)行數(shù)據(jù)的封裝傳到GUI 中。
（1）創(chuàng)建 module并初始化
需要創(chuàng)建添加module初始化便于 JS 中導(dǎo)入該模塊。
1static?js_object_t?js_message_obj?=?JS_ECMA_VALUE_UNDEFINED;2static?void?js_message_info_free(void?*native)3{4????js_message_obj?=?JS_ECMA_VALUE_UNDEFINED;5????rt_kprintf("==>?js_message_obj?=?JS_ECMA_VALUE_UNDEFINED;\n");6}78static?const?js_object_native_info_t?js_message_info?=9{ 10????.free_cb?=?js_message_info_free 11}; 12 13 14js_object_t?example_module_init(void) 15{ 16????js_object_t?obj?=?js_create_object(); 17 18????if?(js_resolve_error(obj)) 19????????return?js_create_null(); 20????rt_kprintf("==>?module_init\n"); 21 22????js_message_obj?=?obj; 23????js_emitter(js_message_obj,?js_create_undefined()); 24????js_set_property_native_pointer(js_message_obj,?"_free_cb",?NULL,?&js_message_info); 25 26????return?obj; 27} 28JS_MODULE(example_module,example_module_init)注意：這里的example_module在 js 中
（2）封裝數(shù)據(jù)傳輸函數(shù)
在 C代碼層到JS腳本層主要是通過事件監(jiān)聽機(jī)制異步上報數(shù)據(jù)或觸發(fā)JS邏輯主動到C層取數(shù)據(jù)；當(dāng)前異步機(jī)制是通過GUI的消息隊列實(shí)現(xiàn)，先往GUI的消息隊列發(fā)送消息，然后GUI收到對應(yīng)消息后觸發(fā)監(jiān)聽回調(diào)，所以需要js_message_send_data和js_callback_message函數(shù)，可以直接從示例代碼中拷貝過來使用。
（3）在解析數(shù)據(jù)后把數(shù)據(jù)傳到界面顯示
在rw007_ble_ntf_handle的函數(shù)中添加把解析數(shù)據(jù)后把數(shù)據(jù)傳到界面顯示的功能，只需要使用js_message_send_data函數(shù)進(jìn)行傳輸數(shù)據(jù)即可。
說明：
需要注意js_message_send_data("mi_data", value);這里的mi_data,后面UI界面中將通過這個屬性來接收數(shù)據(jù)。
（4）編譯固件，燒錄程序。
根據(jù)前面的步驟操作，這里柿餅派的固件已經(jīng)準(zhǔn)備好了，下面需要創(chuàng)建 UI 工程進(jìn)行界面顯示米家藍(lán)牙溫濕度計2代設(shè)備的溫濕度數(shù)據(jù)。
創(chuàng)建 UI 工程顯示米家藍(lán)牙溫濕度計2代設(shè)備的溫濕度數(shù)據(jù)
關(guān)于UI界面工程的創(chuàng)建，這里不做具體說明，可以參考 SDK 目錄下docs\2-PersimM3_UI_Quick_Start.pdf文檔的操作，這里只說明核心部分的操作。
(1) UI 工程界面控件布局
由于這里只做數(shù)據(jù)顯示，所以僅需要放置幾個 Label控件，為了美觀些這里也特意放置了一些圖標(biāo)和設(shè)置背景圖片。
(2) JS 代碼的編寫
主要通過require導(dǎo)入example_module，這里的example_module是前面C代碼中初始化過的，然后通過this.example_module.on("mi_data",function(data){});進(jìn)行數(shù)據(jù)解析，并把數(shù)據(jù)更新到UI界面中。這里的mi_data也是需要與C代碼中配對使用的。
1var?page?=?{23????/*?此方法在第一次顯示窗體前發(fā)生?*/4????onLoad:?function?(event)?{5????????this.example_module?=?require("example_module");6????????console.dir(this.example_module);7????????var?that?=?this;8????????function?insertStr(soure,?start,?newStr)?{9????????????return?soure.slice(0,?start)?+?newStr?+?soure.slice(start); 10????????} 11 12????????this.example_module.on("mi_data",function(data){ 13 14????????????//temp=3205mC,hum=54%,v_bat=2766mV 15????????????//data_length:32 16????????????s_l1?=?data.indexOf(',') 17????????????temp_data?=data.substring(0,s_l1) 18????????????temp_value_l?=?temp_data.indexOf('=') 19????????????temp_value1?=?temp_data.substring(temp_value_l+1,temp_data.length?-2?) 20????????????temp_value=insertStr(temp_value1,2,"."); 21????????????s_l2?=?data.lastIndexOf(',') 22????????????hum_value?=?data.substring(s_l1+5,s_l2) 23????????????vbat_data?=??data.substring(s_l2+7,data.length?-2) 24????????????vbat_value=insertStr(vbat_data,1,"."); 25????????????that.setData({temp_value?:?temp_value+'℃'}); 26????????????that.setData({hum_value?:?hum_value}); 27????????????that.setData({bat_value?:?vbat_value+'V'}); 28????????}); 29????}, 30 31????/*?此方法展示窗體后發(fā)生?*/ 32????onResume:?function?(event)?{ 33 34????}, 35 36????/*?當(dāng)前頁狀態(tài)變化為顯示時觸發(fā)?*/ 37????onShow:?function?(event)?{ 38 39????}, 40 41????/*?當(dāng)前頁狀態(tài)變化為隱藏時觸發(fā)?*/ 42????onHide:?function?(event)?{ 43 44????}, 45 46????/*?此方法關(guān)閉窗體前發(fā)生?*/ 47????onExit:?function?(event)?{ 48 49????}, 50}; 51 52Page(page); 53 54page?=?0;(3) 下載 UI 工程到柿餅派，體驗(yàn)效果
UI 工程下載完成后，在 調(diào)試串口的msh命令行中輸入ble_example_start，然后觀察UI界面的效果。
1msh?/>ble_example_start2ble_example_init3ble_example_connect4str_addr:?A4:C1:38:35:52:945mac?addr:?94:52:35:38:c1:a46ble?data?input?packet?resp_type:?1,?len:?467RW007_BLE_NTF_TYPE_CONNECT8connect?event?status:?0,?conn_handle:?19our_id_type:0?our_id_addr:?48:00:42:8c:47:c9 10peer_id_type:0?peer_id_addr:?a4:c1:38:35:52:94 11conn_itv:80,?conn_latency:0,?conn_suptout:256,?role:0 12msh?/>ble?data?input?packet?resp_type:?1,?len:?13 13RW007_BLE_NTF_TYPE_NOTIFY_RX 14conn_handle:1,?attr_handle:54,?rcv?(notification)?length:5,?data: 1500000000:?28?0B?42?A9?0A???????????????????????????????????(.B.. 16temp=2856?mC,hum=66%,v_bat=2729mV 17cres=temp=2856mC,hum=66%,v_bat=2729mV? 18==>?js_message_send_data?start 19==>?js_message_send_data?end 20value: 21==>?js_callback_message?start 22==>?js_callback_message?end此時，柿餅派的界面就顯示米家藍(lán)牙溫濕度計2代設(shè)備的溫濕度和電量的數(shù)據(jù)。
總結(jié)
經(jīng)過這次使用柿餅派上的 RW007 WIFI 模塊學(xué)習(xí) BLE 功能的使用和讀取米家溫濕度計數(shù)據(jù)顯示在界面上的過程中，學(xué)會 RW007 上如何使用 BLE 功能和鞏固了柿餅派JS與C 之間的數(shù)據(jù)交互的操作，在這次僅是使用了BLE 的初始化和連接功能，希望在后面使用更多的功能制作更多有趣的作品與大家分享。
