嗨，我们有N5244 PNAx。我必须使用具有10dB源衰减器的Ecal套件进行全双端口校准。校准后得到的回波损耗约为-25dB。现在我改变源衰减器20db，回波损耗变化-10dB。任何人都可以告诉为什么这是在讨价还价？ 以上来自于谷歌翻译 以下为原文hi we have N5244 PNAx. I have to full two port calibration Using Ecal kit with source attenuator of 10dB. after calibration got the return loss is about -25dB. Now i m changing source attenuator 20db, Return loss change -10dB. can any one tell why this is happing?

你好，IM使用434 3W在莱尔德英镑LWB的WWER载体板与STM32 F411发现板。链接：英镑LWB Wi-Fi+蓝牙低能耗（BLE）模块并且IM使用Wide IDE V1.1。问题是它不起作用。使用的应用程序是“SNIP.APSTA”和“SNIP .SCAN”，APSTA有更多的UART调试输出，因此我在这里张贴：启动VWICEDY0.60.1.0.0.0.00 85平台LSRSTELLIN 900950初始化启动th5.x v5.8初始化NETX V5.10Sp3创建包池用DE/0初始化WSDD SDIO接口不能设置国家代码WSDD SDIO接口初始化失败：结果20020000 00:00: 0 WICED测井系统初始化加入：这里没有1986：事件（接口、类型、状态、原因）：WWDJSTAI接口未知的WLCKEYSTATESUX成功WLCKEYwwd_sdpcm_send_ioctl（wlc_disassoc）失败：2011年WWDJWiFixJoin：不准备收发（Err 1006）；左网络失败连接（Err 1006）未能加入：这里没有加入：这里没有wwd_sdpcm_send_ioctl（wlc_disassoc）失败：2011年WWDJWiFixJoin：不准备收发（Err 1006）；左网络失败连接（Err 1006）未能加入：这里没有加入：这里没有wwd_sdpcm_send_ioctl（wlc_disassoc）失败：2011WWDJWiFixJoin：不准备收发（Err 1006）；左网络失败连接（Err 1006）未能加入：这里没有0001 00∶00：每1000毫秒21.230次打0.0.0次，每次3毫秒，超时900毫秒。23201：事件（接口、类型、状态、原因）：WWDYAPAPI接口未知的WLCKEYSTATUSSIN成功WLCKEY错误：wwd_wifi_start_ap失败0002 00:00: 21.273未能提出“界面它不能设置国家代码，我认为错误是由国家代码错误引起的。WiFi固件被下载到Flash（构建字符串中的DeLoad应用程序），Logic分析器显示这个Fimware被发送到WiFi芯片。设置国家到美国也没有。ResultCode 2002意味着“wwd_wlan_badarg”。在我读过的源代码中，设置国家代码是第一次需要WiFi芯片来响应。看来这不是问题，因为逻辑分析仪显示芯片正在响应。在AalayZER上，我可以看到命令被发送到WiFi芯片，芯片通过拉低DAT1引脚请求中断。在STM32读取响应。没有人知道那会是错的吗？我非常感谢你的帮助。问候语马丁 以上来自于百度翻译 以下为原文Hello,im using the 4343W on a Laird Sterling-LWB for WICED Carrier Board with the STM32F411 Discovery Board.Link: Sterling-LWB Wi-Fi + Bluetooth Low Energy (BLE) Module And im using the WICED IDE v6.1. The Problem is that it doesnt work.The used apps are "snip.apsta" and "snip.scan", apsta has more UART debugoutputs therefore i post it here: Starting WICED vWiced_006.001.000.0085Platform LSRSTERLING_00950 initialisedStarted ThreadX v5.8Initialising NetX v5.10_sp3Creating Packet poolsWWD SDIO interface initializing with DE/0 Could not set Country code WWD SDIO interface initialization FAILED: result 20020000 00:00:00.000 wiced logging system is initialized Joining : nothinghere1986: Event (interface, type, status, reason): WWD_STA_INTERFACE Unknown WLC_E_STATUS_SUCCESS WLC_E_REASON_INITIAL_ASSOCwwd_sdpcm_send_ioctl(WLC_DISASSOC) failed:2011wwd_wifi_join: not ready to transceive (err 1006); left network Failed join (err 1006) Failed to join : nothinghere Joining : nothingherewwd_sdpcm_send_ioctl(WLC_DISASSOC) failed:2011wwd_wifi_join: not ready to transceive (err 1006); left network Failed join (err 1006) Failed to join : nothinghere Joining : nothingherewwd_sdpcm_send_ioctl(WLC_DISASSOC) failed:2011wwd_wifi_join: not ready to transceive (err 1006); left network Failed join (err 1006) Failed to join : nothinghere0001 00:00:21.230 Pinging 0.0.0.0 3 times every 1000ms with a 900ms timeout.23201: Event (interface, type, status, reason): WWD_AP_INTERFACE Unknown WLC_E_STATUS_SUCCESS WLC_E_REASON_INITIAL_ASSOCError: wwd_wifi_start_ap failed0002 00:00:21.273 Failed to bring up the softAP interface It cannot set the countrycode and i think the errors after that arise from the countrycode error.The WIFI Firmware is downloaded to the flash (download_apps in the Buildstring) and the Logicanalyzer shows that this Fimware is send to the WIFI Chip.Setting the Countrycode to the United States also fails.The Resultcode 2002 means "WWD_WLAN_BADARG". In the Sourcecode I had read, that setting the Countrycode is the first time there the WIFI chip is required to respond.It seems that this is not the problem, because the Logicanalyzer shows that the Chip is responding.On the Analayzer I can see that the Command is send to the WIFI Chip and the Chip is requesting an Interrupt by pulling the DAT1 Pin LOW.After that the STM32 reads the Response. Does anyone know thats going wrong?I really appreciate your help. GreetingsMartin
