  • Re: WISE-1520 and Azure IoT

    Yes, you can download Azure IoT agent from MS website and develop what your need by our WISE-DK1520 SDK, the WISE-PaaS/RMM is our default offering to help you easy development your web application by RESTAPI. 

    The WISE-PaaS/RMM is also running on the Azure IaaS, you can host and operate that VM by yourself as well, I highly recommend you to leverage it to mitigate future maintenance problem. such as change cloud provider or private cloud demand. 
  • Re: 眾多發展中的物聯網標準,專家的看法如何?

    研華就這些在物和物之間互通性的標準協定有幾種看法~~

    1. 就使用應用面來看,工業務聯網中會以OIC/OCF和Thread比較接近工業的應用,但是這兩個的標準推出較晚,使用並未達到廣泛應用的程度,就這一方面來說,研華會持續將兩個標準列入高度觀察名單,並且等市場的成熟度達到,這等待也是讓這些所謂標準聯盟自行能達到共識,另如今年OIC就成立OCF將UPnP等標準納入,並且微軟和Qualcomm等原本是Allseen創立成員加入OCF的聯盟內,由此可見這IoT的標準也在做統一的轉變,可以預見未來Allseen和OIC會有互通性的可能。

    2. 廣泛面來看,Allseen的Alljoyn是現階段使用者和開發者就完整的一個標準,在研華的IoT geatway中也推出Win10 和 Yocto的兩個不同作業系統的Alljoyn解決方案,研華在Alljoyn上也開發了IoT gateway的加值軟體服務,另如研華Alljoyn上整合研華SUSI API針對研華的硬體可以做監測和控制的Alljoyn service, 也在gateway 中的 node-red上開發出Alljoyn的service nodes。讓購買研華的gateway starter kit 的使用者能快速開發IoT專案。

    而就 Thread來說,研華也和ARM mbed結為聯盟,在mbed上也將 Thread列入最新的mbed OS標準,如此一來研華推出的M2.COM的 sensor node未來會標準搭載 mbed OS,在sensor端的thread標準也能支援。
    最後就Apple Homekit來說,因為此標準為smart home and moblie的應用,並且開放程度較低,研華並未將此標準列入賢先期的考量。
  • Re: 淺論MQTT通訊協定

    The specification does not specify the meaning of "small code foot print" or the meaning of "limited network bandwidth". Thus, the protocol's availability for use depends on the context. In 2013, IBM submitted MQTT v3.1 to the OASIS specification body with a charter that ensured only minor changes to the specification could be accepted. MQTT-SN is a variation of the main protocol aimed at embedded devices on non-TCP/IP networks, such as Zigbee, Z-wave and so on.

    Base this background, Advantech has been adapted the MQTT-SN on the RTOS system specially on resource constricted MCU devices. futher information will be described this section soon.
