Kuhlelo lokusebenza lwe-Bluetooth Data Module, inobudlelwano phakathi kwe-Master and Slave Mode
1. Ithini I-Master Mode kanye ne-Slave Mode?
I-Master Mode: Idivayisi ye-Bluetooth ekwi-Master Mode, ingaskena amanye amadivaysi e-Bluetooth ukuthi yimaphi amadivaysi akwiModi yesigqila. Ngokuvamile, i-Feasycom Bluetooth Master Module ingaxhuma idivayisi yesigqila ye-Bluetooth engu-10. I-Bluetooth Master idivayisi ebizwa nangokuthi isithwebuli noma i-Initiator.
I-Slave Mode: Idivayisi ye-Bluetooth ku-Slave Mode, ayisekeli idivayisi ye-Bluetooth yocwaningo. Isekela kuphela ukuxhunywa idivayisi eyinhloko ye-Bluetooth.
Lapho i-Master nedivaysi yesigqila ixhuma, ingathumela futhi yamukele idatha kusuka komunye nomunye nge-TXD, RXD.
2. Iyini i-TXD ne-RXD:
I-TXD: ukuphela kokuthumela, ngokuvamile kudlalwa njengesidlulisi sabo, ukuxhumana okuvamile kufanele
uxhumeke kuphinikhodi ye-RXD yenye idivayisi .
I-RXD: indawo eyamukelayo, evame ukudlalwa njengendawo yokwamukela, ukuxhumana okuvamile kufanele kuxhunywe ku-TXD Pin yolunye idivayisi.
I-Loop Test (TXD Xhuma ku-RXD):
Ukuze uhlole ukuthi imojuli ye-Bluetooth inekhono elivamile lokuthumela nokwamukela idatha, ungasebenzisa idivayisi ye-Bluetooth(i-smartphone) ukuze uxhume kumojula ye-Bluetooth, bese i-TXD Pin yemojula ye-Bluetooth ixhume ku-RXD Pin, ithumele idatha nge-Smartphone Bluetooth. uhlelo lokusebenza losizo, uma idatha etholiwe ifana nedatha ethunyelwe ngohlelo lokusebenza losizo lwe-Bluetooth, lokho kusho ukuthi imojuli ye-Bluetooth isebenza esimweni esihle.
