CHT_Client_NB-IOT

Python client application SIM7000C of NB-IOT module on Raspberry Pi, SIM7000C終端應用運行在樹莓派上, SIM7000C NB-IoT/LTE/GPRS 擴展板模組, CHT SIM card(大卡) 採用中華電信CAT. M1(門市申請即可, 據說已經改為企業才可申請) 我使用的SIM7000C NB-IoT HAT串口似乎有問題(/dev/ttyAMA0), 無法使用UART只能用USB port(/dev/ttyUSB3) SIM7000C NB-IoT HAT與Raspberry pi通訊時要注意SIM7000C模組速度較慢, 注意反饋訊息的檢查, 否則會採坑!!!

1. Close power-saving of the display on Raspberry Pi

先關閉視窗下螢幕休眠功能(當然也可以不用關閉)

sudo nano /etc/lightdm/lightdm.conf

• [SeatDefaults]
• ...
• #xserver-command=X #Change to as below
• xserver-command=X -s 0 –dpms
• ...

2. Auto run application after log-in termainal in the X-Windows mode.

視窗模式下自動開啟一個終端機模式(用戶登入或自動登入), 並運行應用程序

sudo nano /home/pi/.config/autostart/autoboot.desktop

• ...

• [Desktop Entry]

• Type=Application

• Name=MyApplicationRun

• #Exec = lxterminal -e /home/pi/autorun.sh #運行掛機 applivcation close aftern run 5day

• Exec = lxterminal -e "bash -c /home/pi/autorun.sh;bash" #運行測試(Stay Bash)
