Loaʻa nā huahana Bluetooth āpau i ka MCU, akā pehea e hana ai i ka kamaʻilio ma waena o ka MCU a me ka Module Bluetooth? I kēia lā e aʻo ʻoe pehea.
Lawe i ka BT906 ma ke ʻano he laʻana:
1. Hoʻohui pono i ka MCU a me ka module Bluetooth.
ʻO ka maʻamau, ʻike paha ʻoe e hoʻohana wale iā UART (TX / RX) a laila hiki ke kamaʻilio .
Kou MCU TX pili i BT906 module's RX. E ʻoluʻolu e nānā inā ʻoe e hana like me kēia?
Inā ua hōʻoia ʻoe ʻaʻohe pilikia kaapuni, a laila hele mākou i ka ʻanuʻu 2
2. E hōʻoia ua maikaʻi ka ʻāpana Lako.
1) Hoʻohui i ka TX RX o ka module i ke kamepiula ma o ka 3.3V USB Transfer i Serial Port
2) Wehe 'Feasycom Serial Port', koho i ke awa pili, Baurd Rate:115200, Koho: New Line
3) E hoʻouna i ka ''AT+VER', inā he pane:+VER=xxxxx,ʻo ia hoʻi, ua maikaʻi ka hardware.
3.E hōʻoia i ka ʻāpana lako polokalamu ua maikaʻi.
1) E hoʻouna i ka '' AT + MODE = 2, a laila e hoʻololi i ke ʻano huna
2) E hoʻohana i ke kelepona pili i ka mea huna i kapa ʻia ʻo Feasycom
3) E wehe i ka faila txt e koho i ka pihi
4) Hoʻouna hexadecimal
41 54 2B 48 49 44 53 45 4E 44 3D 32 2C 00 04 0D 0A. A laila e loaʻa ke kelepona: a
A T + H I D S END = 2 , \r \n
00: 'Kī hoʻomalu'' waiwai
04: "waiwai huna" o "a"
No nā kikoʻī hou aku e pili ana i ka loaʻa ʻana o ke kamaʻilio modula bluetooth me MCU, e ʻoluʻolu e kelepona i ka hui feasycom
Makemake ʻoe e ʻike pehea e hoʻonui ai i ka firmware o ka MCU me ke kelepona ʻole? E ʻoluʻolu e kipa ma aneʻi: https://www.feasycom.com/how-to-upgrade-mcus-firmware-wirelessly.html
