Cishe yonke imikhiqizo ye-Bluetooth inama-MCU, kodwa Kwenziwa Kanjani Ukuxhumana Phakathi kwe-MCU ne-Bluetooth Module? Namuhla uzofunda ukuthi kanjani.
Ukuthatha i-BT906 njengesibonelo:
1.Xhuma i-MCU kanye nemojuli ye-Bluetooth kahle.
Imvamisa ungazi ukuthi udinga nje ukusebenzisa i-UART (TX/RX) bese ukwazi ukuxhumana.
I-MCU TX yakho ixhume ku-RX yemojuli ye-BT906. Sicela uhlole ukuthi usuvele wenza kanje ?
Uma uqinisekise ukuthi azikho izinkinga zesekethe, siya esinyathelweni sesi-2
2. Qiniseka ukuthi Ingxenye Yezingxenyekazi Zekhompyutha ilungile.
1) Xhuma i-TX RX yemojula kukhompyutha ngokusebenzisa i-3.3V USB Transfer to Serial Port
2)Vula i-''Feasycom Serial Port '', khetha imbobo ehlobene ,Isilinganiso se-Baurd :115200 ,Khetha :Umugqa Omusha
3) Thumela u-''AT+VER '' ,Uma kukhona impendulo :+VER=xxxxx, kusho ukuthi ihadiwe ilungile.
3.Qinisekisa ukuthi ingxenye yesofthiwe ilungile.
1)Thumela okuthi ''AT+MODE=2, khona-ke izoshintsha ibe imodi efihliwe
2)Sebenzisa umakhalekhukhwini oxhunywe kudivayisi efihliwe ebizwa nge-Feasycom
3) Vula ifayela le-txt ukuze ukhethe ikhesa
4)Thumela i-hexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. Khona-ke umakhalekhukhwini uzothola: a
A T + H I D S END = 2 , \r \n
00: ''ukhiye wokulawula'' inani
04: ''inani elifihliwe'' le-''a ''
Ukuze uthole imininingwane eyengeziwe mayelana nendlela yokuthola ukuxhumana kwemojuli ye-bluetooth ne-MCU, vele ukhululeke ukuxhumana nethimba le-feasycom
Uyafuna ukwazi ukuthi ungayithuthukisa kanjani i-firmware ye-MCU ngaphandle kwentambo? Sicela uvakashele lapha: https://www.feasycom.com/how-to-upgrade-mcus-firmware-wirelessly.html
