Pafupifupi zida zonse za Bluetooth zili ndi ma MCU, koma Mungapangire Bwanji Kulankhulana Pakati pa MCU ndi Bluetooth Module? Lero mukadaphunzira momwe.
Kutengera BT906 monga chitsanzo:
1.Lumikizani MCU ndi gawo la Bluetooth moyenera.
Nthawi zambiri mutha kudziwa kuti muyenera kungogwiritsa ntchito UART (TX / RX) ndiye mutha kulumikizana.
MCU TX yanu yolumikizidwa ku RX ya module ya BT906.Chonde onani ngati mwatero kale?
Ngati mwatsimikizira kuti palibe vuto la dera, ndiye tipita ku sitepe 2
2. Onetsetsani kuti Gawo la Hardware lili bwino.
1) Lumikizani TX RX ya gawolo ku kompyuta kudzera pa 3.3V USB Transfer kupita ku seri Port
2) Tsegulani '' Feasycom Serial Port '', sankhani doko lofananira, Mlingo wa Baurd:115200, Sankhani: Mzere Watsopano
3) Tumizani ''AT+VER'',Ngati pali yankho:+VER=xxxxx, ndiye kuti hardware ili bwino.
3.Make kuonetsetsa kuti pulogalamu mbali bwino.
1) Tumizani '' AT + MODE = 2 , ndiye idzasintha kukhala yobisika
2) Gwiritsani ntchito foni yam'manja yolumikizidwa ku chipangizo chobisika chotchedwa Feasycom
3) Tsegulani fayilo ya txt kuti musankhe cholozera
4) Tumizani hexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. Kenako foni yam'manja ilandila: a
A T + H I D S END = 2 , \r \n
00: mtengo wa '' control key''
04: ''mtengo wobisika'' wa '' a ''
Kuti mudziwe zambiri za momwe mungapezere Bluetooth gawo kulankhulana ndi MCU, omasuka kulankhula ndi gulu feasycom
Mukufuna kudziwa momwe mungasinthire firmware ya MCU opanda zingwe? Chonde pitani kuno: https://www.feasycom.com/how-to-upgrade-mcus-firmware-wirelessly.html
