Phantse zonke iimveliso zeBluetooth zineeMCU, kodwa Ulwenziwa Njani unxibelelwano phakathi kweMCU kunye neBluetooth Modyuli? Namhlanje uya kufunda malunga nendlela.
Ukuthatha iBT906 njengomzekelo:
1.Qhagamshela i-MCU kunye nemodyuli yeBluetooth ngokufanelekileyo.
Ngesiqhelo unokwazi ukuba ufuna nje ukusebenzisa i-UART (TX/RX) emva koko unokunxibelelana.
I-MCU TX yakho iqhagamshelwe kwi-RX yemodyuli ye-BT906.Nceda ukhangele ukuba sele uyenza ngolu hlobo?
Ukuba uqinisekisile ukuba akukho zingxaki zesekethe, ngoko siya kwinyathelo lesi-2
2. Qinisekisa ukuba iNdawo yeHardware ilungile.
1) Qhagamshela i-TX RX yemodyuli kwikhompyuter nge-3.3V Ugqithiselo lwe-USB ukuya kwi-Serial Port.
2) Vula ''Izibuko leFeasycom Uthotho '', khetha izibuko eliyeleleneyo ,Inqanaba leBaurd :115200 ,Khetha :Umgca omtsha
3) Thumela u-''AT+VER '' ,Ukuba kukho impendulo :+VER=xxxxx, ngoko kuthetha ukuba ihardware ilungile.
3.Qinisekisa ukuba inxalenye yesoftware ilungile.
1)Thumela ''AT+MODE=2, emva koko iya kutshintsha ibe kwimo efihlakeleyo
2)Sebenzisa iselula eqhagamshelwe kwisixhobo esifihliweyo esigama linguFeasycom
3) Vula ifayile ye-txt ukukhetha ikhesa
4)Thumela ihexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. Emva koko iselula iya kufumana: a
A T + H I D S END = 2 , \r \n
00: ''iqhosha lokulawula'' ixabiso
04: ''ixabiso elifihliweyo'' le'' a ''
Ukufumana iinkcukacha ezithe vetshe malunga nendlela yokufumana unxibelelwano lwemodyuli yebluetooth kunye ne-MCU, vele uzive ukhululekile ukuqhagamshelana neqela le-feasycom
Ngaba uyafuna ukwazi ukuba ungayiphucula njani i-firmware ye-MCU ngaphandle kwamacingo? Nceda undwendwele apha: https://www.feasycom.com/how-to-upgrade-mcus-firmware-wirelessly.html
