Kusan duk samfuran Bluetooth suna da na MCU, amma Yaya ake yin Sadarwa Tsakanin MCU da Module na Bluetooth? A yau za ku koyi yadda.
Ɗaukar BT906 a matsayin misali:
1.Haɗa MCU da na'urar Bluetooth da kyau.
Yawancin lokaci kuna iya sanin cewa kawai kuna buƙatar amfani da UART (TX / RX) sannan ana iya sadarwa.
MCU TX ɗinku ya haɗa da BT906 module's RX. Da fatan za a duba idan kun riga kun yi haka?
Idan kun tabbatar da cewa babu matsalolin da'ira, to sai mu je mataki na 2
2. Tabbatar da Sashin Hardware yayi kyau.
1) Haɗa TX RX na module ɗin zuwa kwamfutar ta hanyar Canja wurin USB na 3.3V zuwa Serial Port.
2) Buɗe ''Feasycom Serial Port', zaɓi tashar tashar jiragen ruwa mai alaƙa, Baurd Rate: 115200, Zaɓi: Sabon Layi
3) Aika ''AT+VER'', idan akwai amsa:+VER=xxxxx, to yana nufin hardware ba laifi.
3. Tabbatar cewa sashin software ba shi da kyau.
1) Aika ''AT+MODE=2 , sannan zai canza zuwa yanayin ɓoye
2) Yi amfani da wayar hannu da aka haɗa zuwa na'urar ɓoye mai suna Feasycom
3) Bude fayil ɗin txt don zaɓar siginan kwamfuta
4) Aika hexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. Sannan wayar salula za ta karbi: a
A T + H I D S KARSHEN = 2 , \r \n
00: ''maɓallin sarrafawa'' ƙima
04: '' boye darajar '' '' a ''
Don ƙarin cikakkun bayanai game da yadda ake samun sadarwar module bluetooth tare da MCU, kawai jin daɗin tuntuɓar ƙungiyar feasycom
Kuna son sanin yadda ake haɓaka firmware na MCU ba tare da waya ba? Da fatan za a ziyarci nan: https://www.feasycom.com/how-to-upgrade-mcus-firmware-wirelessly.html
