IoT software engineer

谷林運算股份有限公司(Goodlinker)

主要負責物聯網閘道的軟體開發和API連線。 一開始這項工作主要是對系統進行重構，利用docker技術解決嵌入式系統中交叉編譯CMAKE函式庫不穩定的問題。 比較有挑戰性的部分是如何將即時的modbus連接狀態傳輸到前端，因為連接是否成功最初是由底層modus驅動程式庫lmodbus API決定的。 有趣的是底層的連結狀態如何向上層傳遞，而WEB層也必須能夠知道連線狀態是否成功。

Eng/ Ver. 

Mainly responsible for the software development and API connection of the IoT gateway. At the beginning, this work was mainly to restructure the system, and use docker technology to solve the problem of unstable cross-compiled CMAKE libraries in embedded systems. The more challenging part is how to transmit the real-time modbus connection status to the front end, because the success of the connection is originally determined by the underlying modus driver library lmodbus API. What is interesting is how to transfer the underlying connection status to the upper layer, and the WEB layer must also be able to know whether the connection status is successful or not.

Familiar Technology:

a. AWS mqtt API
b. C++ web OATPP rest API
d. Modbus
e. Docker
f. Embedded Linux
g Qt5
