Nyob zoo sawv daws.

Nov yog Cov Lus Qhia Txog Yuav Ua Li Cas Hais Lus Bluetooth Siv Raspberry Pi. Qhov no tau ua tom qab kev teeb tsa tshiab ntawm Raspbian tshiab (raws li ntawm 2020-10-31.) Hauv Cov Lus Qhia no peb yuav hloov pauv Raspberry Pi kom tau txais lub suab hla Bluetooth thiab tso tawm nws los ntawm kev ua hauv 3.5 lub suab tso. Yog tias koj siv Raspberry Pi 1 lossis 2 ces koj yuav tau siv cais Bluetooth Adapter. Txog qhov Qhia Qhia no peb yuav siv Raspberry Pi 3B.

Khoom siv

Raspberry Pi 1, 2, 3 lossis 4.

Hais lus nrog 3.5 lub suab tso suab.

Lub hwj chim muab rau Raspberry Pi.

Mouse thiab Keyboard rau Raspberry Pi (lossis koj tuaj yeem SSH nrog lwm lub khoos phis tawj).

Bluetooth dongle yog siv Raspberry Pi 1 lossis 2.

Kauj ruam 1: Nkag mus rau Raspberry Pi

Cov kauj ruam no yog tus kheej-nkag siab zoo!

Koj yuav tsum tau nkag mus rau hauv Raspberry Pi los ntawm SSH lossis nrog tus saib xyuas, nas thiab keyboard. Yog tias koj nyob hauv Raspian GUI ces qhib Terminal. Yog tias koj yog SSH'ing ces koj yuav nyob ntawd.

Ua ntej koj mus nrog cov kauj ruam tom ntej nws raug nquahu kom paub tseeb tias koj tau hloov kho koj lub system.

sudo apt-tau hloov tshiab

sudo apt-tau hloov tshiab

Qhov no yuav siv ob peb feeb.

Kauj ruam 2: Txheeb tawm Bluetooth

Yog koj nkag mus

sudo systemctl xwm txheej xiav*

ces nws yuav zaum rov qab qee yam zoo li hauv qab no.

pi@raspberrypi: ~ $ sudo systemctl xwm txheej xiav*

Koj yuav pom tias muaj tus lej yuam kev. Peb yuav xub txheeb xyuas cov no.

Thawj qhov peb yuav txheeb yog "Sap tsav tsheb pib ua tsis tiav." thiab "sap-server: Tsis pub ua haujlwm". Nkag mus

sudo nano /lib/systemd/system/bluetooth.service

mus rau hauv lub davhlau ya nyob twg. Nws yuav los nrog qhov no.

[Chav]

Kev piav qhia = Kev pabcuam Bluetooth Cov ntaub ntawv = tus txiv neej: bluetoothd (8) ConditionPathIsDirectory =/sys/class/bluetooth [Service] Hom = dbus BusName = org.bluez ExecStart =/usr/lib/bluetooth/bluetoothd NotifyAccess = main #WatchdogSec = 10 #Restart = on-failure CapabilityBoundingSet = CAP_NET_ADMIN CAP_NET_BIND_SERVICE LimitNPROC = 1 ProtectHome = true ProtectSystem = full [Install] WantedBy = bluetooth.target Alias = dbus-org.bluez.service

Ntxiv

--noplugin = sap

tom qab

ExecStart =/usr/lib/bluetooth/bluetoothd

kom nws zoo li hauv qab no.

[Chav]

Nqe lus piav = Bluetooth kev pabcuam Cov ntaub ntawv = tus txiv neej: bluetoothd (8) ConditionPathIsDirectory =/sys/class/bluetooth [Service] Hom = dbus BusName = org.bluez ExecStart =/usr/lib/bluetooth/bluetoothd --noplugin = sap NotifyAccess = main # WatchdogSec = 10 #Restart = on-failure CapabilityBoundingSet = CAP_NET_ADMIN CAP_NET_BIND_SERVICE LimitNPROC = 1 ProtectHome = true ProtectSystem = full [Install] WantedBy = bluetooth.target Alias = dbus-org.bluez.service

Txuag thiab tawm. (ctrl-x, y, nkag). Ces

sudo rov pib dua

Thaum koj rov qab los ntawm lub davhlau ya nyob twg nkag

sudo systemctl xwm txheej xiav*

Qhov yuam kev yuav tsum tau daws, tshwj tsis yog ib qho.

Ua tsis tiav kev ceev ntiag tug: Tsis lees paub (0x0b)

Nkag mus

sudo systemctl rov pib dua xiav*

kho.

Peb tseem tsis tau tiav. Peb tseem yuav xav tau ntxiv tus neeg siv "pi" rau bluetooth siv

sudo adduser pi bluetooth

pi@raspberrypi: ~ $ sudo adduser pi bluetooth Ntxiv cov neeg siv 'pi' rau pawg `bluetooth '… Ntxiv cov neeg siv pi rau pab pawg bluetooth Ua tiav.

Tom ntej no peb yuav tsum muab bluealsa lub peev xwm los ua suab ntws los ntawm Raspberry Pi lub suab cuam tshuam (uas yog 3.5 lub suab tso).

sudo nano /lib/systemd/system/bluealsa.service

Nws yuav tsum tuaj nrog

[Chav]

Nqe lus piav qhia = BluezALSA tus neeg thov yuav tsum = bluetooth.service Tom qab = bluetooth.service [Kev pabcuam] Hom = tus neeg siv yooj yim = hauv paus ExecStart =/usr/bin/bluealsa

Ntxiv

-p a2dp-qhov chaw -p a2dp-dab dej

tom qab

ExecStart =/usr/bin/bluealsa

ua

[Chav]

Nqe lus piav qhia = BluezALSA tus neeg yuav tsum tau = bluetooth.service Tom qab = bluetooth.service [Kev pabcuam] Hom = tus neeg siv yooj yim = hauv paus ExecStart =/usr/bin/bluealsa -p a2dp -source -p a2dp -sink

Txuag thiab tawm (ctrl-x, y, nkag mus).

Ces

sudo rov pib dua

Qhov no ua rau peb Bluetooth ntau dua lossis tsawg dua npaj tau. Tam sim no peb yuav khub thiab txuas rau peb Raspberry Pi.

Kauj Ruam 3: Pairing, Txuas thiab Ntseeg Siab

Tam sim no peb tau tso tawm cov hauv paus los ua Bluetooth Hais Lus. Tab sis peb tseem yuav tsum muaj peev xwm txuas mus ua suab paj nruag los ntawm nws.

Ua ntej tshaj, nkag mus

sudo bluetoothctl cov

ces

zog on

ces

luam theej duab

ib yam dab tsi zoo li no yuav tsum tuaj

pi@raspberrypi: ~ $ sudo bluetoothctl

hauv qhov piv txwv no peb yuav ua khub thiab txuas rau lub cuab yeej hu ua FarthingsLaptop.

Yog li (hloov chaw nyob mac nrog lub cuab yeej koj yuav txuas rau).

Txog ntawm no koj yuav tsum tau txuas nrog tab sis koj yuav pom tias yog koj ua suab paj nruag, nws tsis ua si los ntawm tus hais lus txuas nrog Raspberry Pi. Qhov ntawd yog qhov peb yuav ua nyob rau theem tom ntej.

Kauj Ruam 4: Ua Si Suab Nkauj

Txog tam sim no koj yuav tsum txuas nrog koj li Raspberry Pi, tab sis tsis muaj suab paj nruag ua si los ntawm tus hais lus.

Koj tuaj yeem kho qhov no los ntawm cov lus txib

bluealsa-aplay 00: 00: 00: 00: 00: 00

Tam sim no koj yuav tsum hnov lub suab los ntawm koj tus neeg hais lus thaum koj tshaj tawm xov xwm, tab sis koj tsis xav kom ua raws cov lus txib no txhua lub sijhawm koj xav ua nkauj, yog li peb yuav ua kom nws khiav ntawm khau raj.

Nkag mus

Ces

sudo rov pib dua

Thaum nws khau raj, txuas thiab ntaus nkauj!

Tam sim no koj yuav tsum muaj lub mloog pob ntseg Bluetooth ua haujlwm tau zoo!

Yog tias koj muaj lus nug dab tsi tawm hauv qab cov lus thiab kuv yuav muab rau lawv sai li kuv tuaj yeem ua tau.

Tsaug rau saib.
