藍牙技術作為一種穩定可靠的2.4G無線射頻技術，，在短距離的數據傳輸方面有著廣泛的應用。在工控、數控自動化、切割機等設備上大多用串口數據傳輸。將 PC機電腦軟件通過串口線與設備進行通信數據交換，是一個全雙工的數據傳輸。串口線采用DB9接口，RS232協議，一般情況在1米長度。
    由于串口電纜有著長度限制以及在布線上受到一些約束，采用深圳紅果電子技術有限公司的藍牙模塊RG-BT10-04/RG-BT10-06（藍牙串口線）則能有著串口線可靠，雙工，數據 不丟包 ，同時能在室內10m通信距離，不受位置，布線等的影響，成為了新型數控機床等設備的首選配件。
紅果電子藍牙工業數控自動化方案操作簡單，完全封裝藍牙協議和串口協議，你只需要在模塊外圍配置IO口高低電平，就能進行波特率設置，通道設置，可以在同一個空間范圍能使用63套設備，互不干擾。本方案采用2個藍牙模塊，一塊是主模塊，通過MAX3232 TTL轉RS232 連接到PC機串口；一塊是從模塊，則可以通過MAX3232連接到設備的RS232接口。設置好模塊的波特率和通道之后，兩邊模塊上電之后則會自動連接形 成透明串口線。PC機往串口發的數據，另外一端則會接收到數據。操作簡單，是理想的替代串口線方案，無需修改現有PC機軟件。
