Hi3863 WiFi/BLE Combo 编译构建
1、获取OH master系统底座
repo init -u git@gitcode.com:openharmony/manifest.git -b master --no-repo-verify repo sync -c repo forall -c 'git lfs pull' bash build/prebuilts_download.sh (如执行不成功，可加上sudo权限)
2、iot connect 组件集成
1、使用git命令克隆communication_iot_connect复制到foundation/communication目录下，将文件夹名称修改为iot_connect。
2、在foundation/communication/iot_connect/iotc.gni修改如下配置
declare_args() {
iot_connect_ble_support = true
iot_connect_wifi_support = true
iot_connect_kv_support = true
iotc_connect_ble_net_cfg_support = true
iotc_connect_wifi_cloud_support = true
其他设置为false
如
iot_connect_ailife_support = false
iot_connect_mbedtls_v2_support = false
iot_connect_mbedtls_psk_support = false
iot_connect_mbedtls_ccm_support = false
}
if (defined(ohos_lite)) {
iot_connect_ble_support = true
iot_connect_sle_support = false
}
3、在foundation/communication/iot_connect/adapter/adapter.gni中修改mbedtls库路径，
将gni文件内的所有的device/soc/hisilicon/hi3863v100/sdk_liteos/open_source/mbedtls/mbedtls_v3.1.0/include路径修改为 device/soc/hisilicon/ws63v100/sdk/open_source/mbedtls/mbedtls_v3.1.0/include
4、修改foundation/communication/iot_connect/adapter/os/cmsis2/iotc_os.c文件中，MS_PER_SECOND 常量修改为100（此tick频率是100Hz而非常见的1000Hz）
#ifndef MS_PER_SECOND #define MS_PER_SECOND 100
5、进入foundation/communication/iot_connect/adapter/kv/oh_lite/iotc_kv.c进行如下修改，避免创建文件报错（hi3863不支持多级目录直接创建，需要手动创建目录）
uint32_t tagLen = strlen(tag);
if (tagLen > MAX_TAG_LEN) {
IOTC_LOGE("tagLen[%u] out of range", tagLen);
return IOTC_ERR_PARAM_INVALID;
}
int ret = fs_adapt_mkdir("/data"); //添加此处
ret = fs_adapt_mkdir("/data/app"); //添加此处
ret = fs_adapt_mkdir("/data/app/iotc"); //添加此处
ret = fs_adapt_mkdir(tag); //添加此处
6、进入foundation/communication/iot_connect/core/infrastructure/utils/utils_mutex_ex.c,注释互斥锁创建，直接return（ws63v100锁的资源有限，若创建锁的话会导致编译失败，此处return）
bool UtilsExMutexLockInner(UtilsExMutex *mutex, uint32_t timeout, const char *func)
{
return true; //添加此处
if (mutex == NULL || func == NULL || mutex->mutexId == NULL) {
IOTC_LOGW("param invalid");
return false;
}
…………
}
void UtilsExMutexUnlockInner(UtilsExMutex *mutex, const char *func)
{
return;//添加此处
if (mutex == NULL || func == NULL || mutex->mutexId == NULL) {
IOTC_LOGW("param invalid");
return;
}
…………
}
7、进入foundation/communication/iot_connect/core/wifi/infrastructure/transport/coap/endpoint/coap_endpoint.c注释掉如下代码。（ws63v100锁的资源有限，若创建锁的话会导致编译失败，此处return）
/*
endpoint->mutex = UtilsCreateExMutex();
if (endpoint->mutex == NULL) {
IOTC_LOGW("mutex create error");
break;
}
*/
8、进入foundation/communication/iot_connect/core/wifi/application/cloud/biz/m2m_cloud_ctl.c可以参考如下改法（云端下发的控制报文解析失败问题修改）：
static int32_t BuildCloudCtlRespMsg(CoapEndpoint *endpoint, const CoapPacket *req, const SocketAddr *addr,
const M2mCloudContext *ctx, IotcJson *respJson)
{
int32_t ret = IOTC_OK;
do {
uint32_t seg = 0;
const CoapOption *reqIdOpt = CoapUtilsFindOption(req,COAP_OPTION_TYPE_REQ_ID, &seg);
if(reqIdOpt == NULL || seg != 1 || reqIdOpt -> value.data == NULL || reqIdOpt -> value.len == 0){
ret = IOTC_CORE_WIFI_M2M_ERR_CLOUD_GET_OPT_REQ_ID;
break;
}
const CoapOption *devIdOpt = CoapUtilsFindOption(req,COAP_OPTION_TYPE_DEV_ID, &seg);
if(devIdOpt == NULL || seg != 1 || devIdOpt -> value.data == NULL || devIdOpt -> value.len == 0){
ret = IOTC_CORE_WIFI_M2M_ERR_CLOUD_GET_OPT_DEV_ID;
break;
}
const CoapOption *userIdOpt = CoapUtilsFindOption(req,COAP_OPTION_TYPE_USER_ID, &seg);
if(userIdOpt == NULL || seg != 1 || userIdOpt -> value.data == NULL || userIdOpt -> value.len == 0){
ret = IOTC_CORE_WIFI_M2M_ERR_CLOUD_GET_OPT_USER_ID;
break;
}
const CoapOption *seqIdOpt = CoapUtilsFindOption(req,COAP_OPTION_TYPE_SEQ_NUM_ID, &seg);
if(seqIdOpt == NULL || seg != 1 || seqIdOpt -> value.data == NULL || seqIdOpt -> value.len == 0){
ret = IOTC_CORE_WIFI_M2M_ERR_CLOUD_GET_OPT_SEQ_NUM_ID;
break;
}
const CoapOption options[] = {
{COAP_OPTION_TYPE_ACCESS_TOKEN_ID, {(const uint8_t *)ctx->tokenInfo.access, strlen(ctx->tokenInfo.access)}},
{COAP_OPTION_TYPE_REQ_ID, {(const uint8_t *)reqIdOpt->value.data, reqIdOpt->value.len}},
{COAP_OPTION_TYPE_DEV_ID, {(const uint8_t *)devIdOpt->value.data, devIdOpt->value.len}},
{COAP_OPTION_TYPE_USER_ID, {(const uint8_t *)userIdOpt->value.data, userIdOpt->value.len}},
{COAP_OPTION_TYPE_SEQ_NUM_ID, {(const uint8_t *)seqIdOpt->value.data, seqIdOpt->value.len}},
};
CoapServerRespParam respParam = {
.req = req,
.type = COAP_MSG_TYPE_NCON,
.code = COAP_RESPONSE_CODE_CONTENT,
.opNum = ARRAY_SIZE(options),
.options = options,
.payload = NULL,
.payloadBuilder = CoapUtilsBuildJsonPayloadFunc,
.payloadUserData = respJson,
.preSize = 0,
};
CoapPacket packet;
ret = CoapServerSendResp(endpoint, &respParam, addr, &packet);
if (ret != IOTC_OK) {
IOTC_LOGW("send e2e ctrl resp msg error %d", ret);
}
} while (false);
return ret;
}
/*
CoapResponeNode *respInfo = M2mCloudCreateCoapNode(endpoint, req, addr, ctx);
if (respInfo == NULL) {
IOTC_LOGW("create cloud resp node error");
return IOTC_ERROR;
}
*/
9、进入foundation/communication/iot_connect/core/wifi/infrastructure/transport/socket/trans_socket_udp.c（加入套接字会失败，且配网走的是tcp），注释掉以下内容：
/*
ret = JoinMulticastGroup(fd, param);
if (ret != IOTC_OK) {
return ret;
}
*/
10、进入foundation/communication/iot_connect/adapter/log/hilog_m/iotc_log.c（添加日志换行，日志才会规则显示）
void IotcLogOutputImpl(uint8_t level, const char *fileName,
const char *funcName, uint32_t line, const char *fmt, ...)
{
const char *tag[6] = {"IC_FATAL", "IC_ERROR", "IC_WARN", "IC_NOTICE", "IC_INFO", "IC_DEBUG"};
(void)fmt;
if (funcName != NULL) {
printf("%s:%s:%u, ", tag[level - 1], funcName, line);
} else {
printf("%s:%s:%u, ", tag[level - 1], fileName != NULL ? fileName : "NULL", line);
}
printf("\r\n"); //添加换行，方便后面查看日志
}
3、ble 接口适配
1、clone communication_nearlink,将communication_nearlink中的openharmony/device/soc/hisilicon/hi3863v100/hi3863_adapter/hals/communication/bluetooth文件夹复制到OpenHarmony源码的device/soc/hisilicon/ws63v100/adapter/hals/communication目录下。
2、在\device\soc\hisilicon\ws63v100\sdk\BUILD.gn中更改为如下配置
lite_component("sdk") {
features = []
deps = [
"//build/lite/config/component/cJSON:cjson_static",
"//device/soc/hisilicon/ws63v100/adapter/hals/communication/bluetooth/services:btservice",
"//device/soc/hisilicon/ws63v100/adapter/hals/communication/sle_lite",
"//device/soc/hisilicon/ws63v100/adapter/hals/communication/wifi_lite/wifiservice",
# "//device/soc/hisilicon/ws63v100/adapter/kal",
]
}
3、在\device\soc\hisilicon\ws63v100\adapter\hals\communication\bluetooth\services\BUILD.gn中，将文件内所有的//device/soc/hisilicon/hi3863v100路径改为//device/soc/hisilicon/ws63v100，例如将//device/soc/hisilicon/hi3863v100/sdk_liteos/include/middleware/services/bts/ble改为//device/soc/hisilicon/ws63v100/sdk/include/middleware/services/bts/ble"，文件路径都要对应起来。
4、lwip协议栈适配
1、foundation/communication/iot_connect/adapter/socket/iotc_socket.c路径下将原头文件替换成以下头文件
#include "lwip/inet.h" #include "lwip/netifapi.h" #include "lwip/sockets.h" #include "iotc_socket.h" #include <stdio.h> #include <stdlib.h> #include <stdbool.h> #include <string.h> #include <sys/socket.h> #include <netdb.h> #include "securec.h" #include "iotc_errcode.h" #include "iotc_network.h" #include "iotc_mem.h" #include "iotc_log.h" #include <sys/time.h> // #include <arpa/inet.h> // #include <unistd.h> // #include <fcntl.h>
如果遇到fcntl或close接口未定义，把fcntl改为lwip_fcntl，close改为lwip_close
2、foundation/communication/iot_connect/adapter/socket/iotc_socket.c文件中的IotcSelect方法中，修改select为lwip_select （改为使用ws63v100 sdk实现的lwip_select去监听套接字，而不是直接使用系统的Select）
int32_t ret = select(maxFd + 1, (readSet == NULL) ? NULL : &read, (writeSet == NULL) ? NULL : &write, (exceptSet == NULL) ? NULL : &except, &timeout); 修改为 int32_t ret = lwip_select(maxFd + 1, (readSet == NULL) ? NULL : &read, (writeSet == NULL) ? NULL : &write, (exceptSet == NULL) ? NULL : &except, &timeout);
5、ws63 sdk适配
1、进入device/soc/hisilicon/ws63v100/sdk/build/config/target_config/ws63/menuconfig/acore/ws63_liteos_app.config（hi3863不支持多级目录直接创建，需要手动创建目录，需要修改CONFIG_LFS_PARTITION_ID为0x21，手动创建才能生效）
CONFIG_LFS_PARTITION_ID=0x21
2、进入device/soc/hisilicon/ws63v100/sdk/open_source/lwip/lwip_adapter/liteos_207/src/arch/sys_arch.c注释掉加锁的地方（ws63v100锁的资源不够，创建锁会失败），如下所示
mbox->first = 0; mbox->last = 0; mbox->is_full = 0; mbox->is_empty = 1; mbox->is_autoexpand = is_auto_expand; // ret = osal_mutex_init(&(mbox->mutex)); //注释掉这行 ret = 0; //添加ret = 0
3、进入device/soc/hisilicon/ws63v100/sdk/open_source/lwip/lwip_v2.1.3/src/api/tcpip.c为保证有足够时间清理tcpip资源，需要添加休眠时间，进行如下修改：
static void tcpip_timeouts_mbox_fetch(sys_mbox_t *tbox, void **msg) { u32_t sleeptime, res; again: LWIP_ASSERT_CORE_LOCKED(); sleeptime = sys_timeouts_sleeptime(); if (sleeptime == SYS_TIMEOUTS_SLEEPTIME_INFINITE) { UNLOCK_TCPIP_CORE(); sys_arch_mbox_fetch(tbox, msg, 0); LOCK_TCPIP_CORE(); return; } else if (sleeptime == 0) { sys_check_timeouts(); /* We try again to fetch a message from the mbox. */ UNLOCK_TCPIP_CORE(); //新增 sys_msleep(100); //新增 LOCK_TCPIP_CORE(); //新增 goto again; } UNLOCK_TCPIP_CORE(); res = sys_arch_mbox_fetch(tbox, msg, sleeptime); LOCK_TCPIP_CORE(); if (res == SYS_ARCH_TIMEOUT) { /* If a SYS_ARCH_TIMEOUT value is returned, a timeout occurred before a message could be fetched. */ sys_check_timeouts(); /* We try again to fetch a message from the mbox. */ goto again; } } #endif /* !LWIP_TIMERS */static void tcpip_thread(void *arg) { struct tcpip_msg *msg; LWIP_UNUSED_ARG(arg); LWIP_MARK_TCPIP_THREAD(); LOCK_TCPIP_CORE(); if (tcpip_init_done != NULL) { tcpip_init_done(tcpip_init_done_arg); } tcpip_init_finish = 1; //@@@add 新增 while (1) { /* MAIN Loop */ #if defined(LWIP_HI3861_THREAD_SLEEP) && LWIP_HI3861_THREAD_SLEEP UNLOCK_TCPIP_CORE(); hi_cpup_load_check_proc(hi_task_get_current_id(), LOAD_SLEEP_TIME_DEFAULT); LOCK_TCPIP_CORE(); #endif LWIP_TCPIP_THREAD_ALIVE(); /* wait for a message, timeouts are processed while waiting */ TCPIP_MBOX_FETCH(MBOXPTR, (void **)&msg); if (msg == NULL) { LWIP_DEBUGF(TCPIP_DEBUG, ("tcpip_thread: invalid message: NULL\n")); LWIP_ASSERT("tcpip_thread: invalid message", 0); UNLOCK_TCPIP_CORE(); //新增 sys_msleep(100); //新增 LOCK_TCPIP_CORE(); //新增 continue; } tcpip_thread_handle_msg(msg); } }
4、进入device/soc/hisilicon/ws63v100/adapter/hals/communication/wifi_lite/wifiservice/source/wifi_device.c文件。（修改扫描信道和按wifi名扫描，才能扫描到wifi）
AdvanceScan修改如下：
params->freqs = 2 ; //新增 sp.ssid_len = params->ssidLen; sp.scan_type = params->scanType; sp.channel_num = params->freqs; sp.scan_type = 2; //新增 hiRet = wifi_sta_scan_advance(&sp); //添加这个修改才能扫描到wifi
ConnectTo函数修改如下（增加启动dhcp，获取ip地址）：
if (StaConnect(0, &assocReq, g_wifiConfigs[networkId].wapiPskType) != WIFI_SUCCESS) {
if (UnlockWifiEventLock() != WIFI_SUCCESS) {
return ERROR_WIFI_UNKNOWN;
}
return ERROR_WIFI_UNKNOWN;
}
if (UnlockWifiEventLock() != WIFI_SUCCESS) {
return ERROR_WIFI_UNKNOWN;
}
StaSetWifiNetConfig(WIFI_CONNECTED); //添加这行，才能启动dhcp，成功获取ip地址
return WIFI_SUCCESS;
5、进入device/soc/hisilicon/ws63v100/adapter/hals/communication/wifi_lite/wifiservice/source/wifi_device.c文件
这里的sdk的DispatchScanStateChangeEvent没有定义，注释掉DispatchScanStateChangeEvent函数调用
for (int i = 0; i < WIFI_MAX_EVENT_SIZE; i++) {
if (g_wifiEvents[i] == NULL) {
continue;
}
// DispatchScanStateChangeEvent(NULL, g_wifiEvents[i], WIFI_STATE_NOT_AVAILABLE);
}
6、进入device/soc/hisilicon/ws63v100/sdk/open_source/lwip/lwip_v2.1.3/src/include/lwip/sockets.h文件，ws63v100中将lwip_select重定向到了系统select。这样调用的就是系统select而不是自身实现的lwip_select了，需要将重定向注释掉。
// #define lwip_select select 将这行注释掉，否则lwip_select调用的是系统select而不是ws63 SDk 自身实现的lwip_select
6、mbedtls修改
在third_party/mbedtls/port/config/config_liteos_m.h这个头文件中，打开MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES宏
#define MBEDTLS_NO_DEFAULT_ENTROPY_SOURCES
7、集成WifiBleCombo的demo
获取hi3863平台 WiFi/BLE Combo demo，将wifi_ble_combo/hi3863文件夹复制到applications/sample/wifi-iot/app 目录下并改名为wifi_ble_demo
8、编译配置
1、\vendor/hihope/nearlink_dk_3863目录下的config.json中添加iot_connect模块
{
"subsystem": "communication",
"components": [
{ "component": "iot_connect", "features":[] }
]
}
2、\device/soc/hisilicon/ws63v100/sdk/build/config/target_config/ws63/config.py
添加如下配置，并删除’ble_lite‘ 、 'sle_lite'
{
'ws63-liteos-app': {
...
'ram_component': {
...
'iotc','wifi_ble_combo','btservice',
}
}
}
3、\device/soc/hisilicon/ws63v100/sdk/libs_url/ws63/cmake/ohos.cmake
添加如下配置，并删除’ble_lite‘ 、'sle_lite'
(${TARGET_COMMAND} MATCHES "ws63-liteos-app")
set(COMPONENT_LIST
... "btservice" "iotc" "wifi_ble_combo" )
endif()
4、\applications/sample/wifi-iot/app/BUILD.gn添加如下配置
lite_component("app") {
features = [ "startup" ]
features += [ "./wifi_ble_demo:wifi_ble_combo" ] //添加这行
}
5、\build\lite\components\communication.json添加如下配置
{
"component": "iot_connect",
"description": "iot_connect based on liteos-m and liteos-a.",
"optional": "true",
"dirs": [
"foundation/communication/iot_connect"
],
"targets": [
"//foundation/communication/iot_connect:iotc_static"
],
"rom": "",
"ram": "",
"output": [ ],
"adapted_kernel": [ "liteos_m", "liteos_a" ],
"features": [],
"deps": {
"third_party": [
],
"kernel_special": {},
"board_special": {},
"components": [
]
}
}
6、工具链添加到环境变量
vim ~/.bashrc # 编辑环境变量 export PATH=~/device/soc/hisilicon/ws63v100/sdk/tools/bin/compiler/riscv/cc_riscv32_musl_100/cc_riscv32_musl/bin # 在环境变量的最后添加一行编译工具链路径信息 source ~/.bashrc # 应用环境变量
9、编译和烧录
