4g模組使用配置步驟
一.聯網設定（ppp模式）
1.輸入lsusb檢視4g模組是否連線成功(bus 003 device 002: id 2c7c:0125為4g模組)
root@bpi-iot-ros-ai:~# lsusb
bus 004 device 001: id 1d6b:0003 linux foundation 3.0 root hub
bus 003 device 002: id 2c7c:0125
bus 003 device 001: id 1d6b:0002 linux foundation 2.0 root hub
bus 002 device 001: id 1d6b:0003 linux foundation 3.0 root hub
bus 001 device 001: id 1d6b:0002 linux foundation 2.0 root hub

1.配置linux服務端
鍵入ssh -fncr 2333:localhost:22 [email protected]
root@bpi-iot-ros-ai:~# ssh -fncr 2333:localhost:22 [email protected]2.配置阿里雲服務端
鍵入ssh -fncl 2555:localhost:2333 localhost
鍵入密碼：zhou1996.
3.本地計算機ssh設定

幾種2 4G無線數傳模組電路
一 幾種2.4g無線數傳模組介紹 無線數傳按傳輸速率區分,分為低速數傳模組和高速數傳模組兩大類,低速數傳模組使用的載頻均較低，一般都在 315mhz,433mhz 和915mhz 這幾個頻段，所以一般最高傳輸速率均不大於150kb s。但這些使用在uhf頻段無線裝置，載波仍具有一定的穿透和繞射能力，...
Arduino 2 4G模組做航模遙控器
萌新第一次發文，多多關照 玩航模估計有七八年了，玩arduino和各類微控制器也有一兩年啦，今年回家以後因為疫情被困在家裡回不去，就尋思著用arduino做個2.4g的遙控和接收。閒話不多說，開始正文。接線還有其他的基礎介紹可以參考凌順實驗室的介紹和示意，我感覺很不錯 arduino 2.4g通訊實...
